Do you have any other questions about eyeglasses? Please let me know! Here is a beginner's guide to glasses in case you want to learn more. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k2dqcCIKQG4.html
Mild myopia & glasses since my mid 20's. No more myopia after cataract surgery a few years ago at age 81. But still have presbyopia (+3.25) and current prescription includes +0.50 sphere correction. Definitely need glasses for reading/close-up, but why is it so comfortable wearing them full time rather than not (progressive lenses), even though my distance vision is 20/20?
Do you remember where you got the glasses you're wearing in the video? I really like that style but haven't been able to find something like it anywhere
Thank you! Yes, I have had many other doctors in the field suggest that too. I would enjoy it but academia comes with a lot of politics and unfortunately, most professors don't get paid very well. Perhaps some day.
Perhaps a guest speaker at University. Of course there would be a fee for your services. You would give a new perspective since you actually work in the field and just don't teach about it.
Hey, i’m sorry for everything you’ve been through, God really wants to let you know that He loves you so much. He sent his one and only Son down, Jesus Christ, to die for you and i while we were still living in sin. With Him you can be made new, you are covered with the Precious Blood of Jesus. Following Him is not going to be easy, cutting off sin, changing ways that you live in sin and/or cutting off friends. Not living like the world can be hard in the beginning. But it really is worth it. Please start reading the Bible and pray to receive Him im in a way that is undeniable. Because He will make Himself known to you. i say this to you in love and compassion. Jesus loves you and start to live for Him. It will be the best opportunity of your life.

Thank you for making this video. I had emergency eye surgery for a detached retina back in December and I'm finally reviewing my old prescription to my new one to see how much of a change it really is.
This is great - super helpful. In 10 years of going to the same eye doctors office, they've never offered to share my vision or prescription measurements. I finally asked this year as I'm trying to wear bifocals and wanted to understand how they're configured. Would love to see content on how bifocals/progressives are configured and measured - and if you haven't already, how glasses should fit, eg when do you need to have the ear pieces adjusted, or the angles of the ear pieces to the lens frames. And - curious how many visits to the eye doc should it take to get the right vision correction? Every year I have to go back multiple times - strength of prescription given is often far too strong. I'm trying really hard to learn as much as I can to help 'correct' when the script is off (and truth be told I don't have time to go to the eye doc 5 and 6 times a year just for 1 pair of glasses)
With a comment like that, I seriously doubt you went to medical school. With nominal research and reading, these prescriptions are easily understood. Anyone who went to medical school would be smart enough to accomplish such self-education. Perhaps you meant some other schooling but certainly not medical school. No offense.
Great information, great video! This video is exactly what we need! The explanation is very easy to understand! Thank you for sharing about Glasses Prescription Explained - How to read your prescription for glasses!

Thanks so much for your expertise. It is just easier that I make my own refractive measurements myself, using my own Snellen and test Lenses. Measurement: 20/20. Refractive STATE IS +0.5 Diopters. Better if you measure yourself.
Thanks great video, but you lost me at the conversion section at the end. What I'd really like to figure out is how to determine the Sphere or Add numbers to correct a mismatched focal length in a pair of specs. For example, a computer screen at arms length is sharp for the Left eye yet I need to lean forward about half that distance for it to be sharp for the Right eye. Do I need to increase the SPH + number or reduce it to enable the Right eye to see text sharp at arms length? Thx :)
My eye doctor still can’t get my right eye prescription right after 3 times. Seems we can get it right in the office, but when the glasses come….blurry vision at certain distances that don’t match my left eye. They check the glasses and the prescription matches. I do use line bi-focals. After 3 times I gave up and will wait until December when I can get new glasses.
What can cause an axis value to change over a 5-month period? I am experiencing poorly corrected vision in my left eye. I had the 5-month-old glasses validated by my ophthalmologist and he tells me they are spot on from the Feb 2024 script. I had another refraction performed today (7/29) and the axis has changed from 171 to 010. The technician performing the refraction told me that this was likely the reason for the poor vision. Thanks in Advance
I suppose I should pay attention to prescription numbers. I have two pairs of glasses. One pair is slightly curved/mostly flat. The other is curved oakley prescription sunglasses. I only truly noticed recently that the oakley sunglasses shift my left eye inward. They move letters ever so slightly inward. (astigmatism left eye only). I'm thinking they are acting like prism glasses given the information presented in the video. Probably explains the random headaches I get when going between the two.
TIL that a prism exists and it may have been a solution for my lazy eye all along.... joy... On the plus side, I did point out the far/nearsightedness based on how big or small glasses make someones eye to several people over the years and my bf has complained about not being able to UNSEE that now
Many people refer to 'perfect' vision as '6/6' or '20/20' (US notation measured in feet), but this is not strictly true - these terms refer to 'average' vision. If you achieve a vision measurement of 6/6, this means that you can see at a distance of 6m what an average person also sees at the same distance.
Hey I have an interesting question So assume that you have two patient with -20.00D (patientA)and +20.00D(patientB ) respectively Without any accommodation power Do they see the same blurry image at far distance ?? Is the image of a -20.00D equivalent to +20.00D?
Hi Good Morning And Thank You For Sharing I Have A Question I Recently Went To Have An Eye Exam I Continue To Get Blepharitis I Get The Sensation Of Something Gritty In My Eye My Doctor Prescribed A Medication Call Xdemvy Will This Help And My Other Question Is Sometimes I Can Look At Certain Objects They Look Like Wavy What Is That ?
Thank you so much! Blepharitis is very common and some people are more prone to getting it than others. Xdemvy is specifically for a certain type of blepharitis that is challenging to get rid of. But in my experience, Xdemvy works like a charm. For the other question, wavyness in the vision can occur for multiple reasons, from anything such as an unstable tear film to migraine headaches to more serious retinal conditions. I wish I could help more but this is something to ask a local doctor about so they can examine the eyes and give a diagnosis. Hope that helps.
Not a medical person. Struggling to understand in layman's terms how one exam produces glasses for bifocals. Having trouble with close up vision even after cataract surgery. I assumed the surgery lenses would have both adjustments for far and near vision. Any extra tweak's would be done with eye glasses. If one of your other videos can help please advise.
Dear Lord 😭 explain like I'm 5😭🥹 I am either looking at my prescription wrong, or I have a very complicated perception. Idk. I know my astigmatism got better, the doc was surprised and mentioned that.
My optician gave me a lens from stock. My axis is 76 and 80. Is this possible for him to have the right axis in stock . Shouldn't they have ordered the lens
❤hi dr what is the highest sphere and what number is the highest you can go on astigmatism cylinder and axis, want the most power, plus the eye muscles higher numbers thanks ❤❤
I have always wondered why eye doctors tell you to wear your distance glasses all day, every day, EVEN when doing close up work. What is the reason for this if people who are nearsighted can see up close?
Some people can take off the distance glasses but it depends on the status/ pull of the eye muscles. For myself, I’m so nearsighted that if I take my glasses off, or don’t wear my contact lenses, then I can see things up close near my face but to keep things single I have to close my eyes. Otherwise I go cross- eyed and start to see double .
During my eye exam, my PD was measured but not written down on my prescription. Before my exam, I checked online (College of Optometrists) that PD is part of the prescription. This may only be true depending where you live in the world. I reminded the staff, doctor, & optician that they are required to provide me with the PD since I paid for an eye exam & a pair of eyeglasses. They still did not give it to me. So I told them I am not leaving until I get it.😉 I got it. Then proceeded to walk through the shop & buy eyeglasses online.😁
Hi, Moving the frame of my single vision lens (-6 sph) down the nose, away from eyes, enables me to read more clearer. Does this mean I am adding plus power when I do this action?
Is there any type of correction when one eye focuses on a different location? This is especially frustrating for me when reading. A sudden change in location causes a disjointed stream of information. But other times the disjointed information is not easily detected which can lead to all kinds of problems.
I recently got a totally botched prescription when I tried to update. The new glasses were too strong and everything over about 20 feet was out of focus. Too late to get a re-do and can't return the glasses. It's so frustrating and I'm so confused about my prescription.
I have been a keratoconus patient since 2010 and currently wearing rgp contact lens on my right eye. My left eye has scarred cornea, can not tolerate Rgp lenses, could you please tell what the treatment of my left eye. Optometrist suggested me to wear Scleral lens.
I am an mbbs doctor and preparing myself for Australian Medical Council exam. I wish to work in Australia as a registered doctor. Will my eye issue cause any problems in my visa processing as a working doctor? Please reply....Love for Bangladesh❤
Hi i am 13 and sometimes get a large chunk of a white spot it can last for a few mins and come and go mabey you can tell me whats wrong so i know if i can get a eye test
Q uestion i went to an optometrist and she gave me axis number of 150/65 R/L three weeks later i saw an opthmalogist and he axis numbers where 35/170 R/L what should i do??
Sounds like the optometrist wrote the prescription in minus cylinder and the ophthalmologist wrote it in plus cylinder. The prescriptions are probably pretty similar. I do have a bias but optometrists study the theory and are trained specifically on refraction where most ophthalmologists study advanced surgery, not refraction. So I would try the prescription from the optometrist first.
Hello doctor I am from Nepal I am keratoconus patent I have done my cxl 2 years back on my left eye with scleral lenses hardly I can get 6/9 vision I don't know what should I do I am depressed please assest me 😭
Hi Dr. If PD is not included in the prescription, then how the glassmaker should know about it? I have heard that a glass with wrong PD can cause vertigo.
Hi. I noticed that you have quite a bit of a stigmatism -1.50 and -1.00 of astigmatism. I’m sure I’ve seen you wear -5.50 contacts before. Do you just wear spherical lenses or torics normally?
Could you make an in-depth video on how to do manifest refraction? I work as an ophthalmic technician and do refractions all day long. However, there would be patients who give the most obscure answers and have weird prescriptions. Or even trying to "fish" for cylinder.
That can be a multitude of reasons. Are you based in the USA? Every form of cataract can cause weird prescription, Keratokonus, it’s definitely something to look at and ask more question to narrow down the problem. At least that’s what I do and it works fine.
People often are hungry for minus. Since minus usually boosts the contrast. rule of thumb would be to only correct with more minus: Sphere -> if visus gets better zylinder -> reduces ghosting and or blurriness which is kinda easy with the right usage of a cross cylinder
Is it possible for a cylinder to go from +1.75, axis 80 to +1.25 axis 70 in a year, and then a year later back to + 1.75, but with an axis at 70, or is it more likely one or both of the last two prescriptions are off? These are not done by professionals but by helpers who don't stay long at the practice. They are either part-time and/or temporary. Some are good. Some are terrible. If my axis is really 80 and off 10 degrees, will this cause vision problems or is my astigmatism low enough that it won't matter? (They did put it years ago at 90, and I was unable to see out of the glasses. I had terrible ghosting.) I will order a cheap pair of glasses online to see, but since my records got screwed up this time too, I'm not sure what axis I'm going to end up with: the 70 one on the prescription or a different one. I'd just like your opinion. I understand you can't give medical advice. Thanks.
I'm an engineer so bear with my geekiness please. I get a prescription and I need additional correction for reading (ADD). But, I don't like the "reading prescription" focal distance being so close because I can't read the dash of my car while driving. If I push the focal point out to about arms length, then I find that the depth of field is so nice and long that I can read a book by holding it just a bit farther away; I can see the dash just fine; and bonus, I things at my feet are in focus. So, what is the formula to push the "reading prescription" focal point out another 12 inches? (I hacked it myself, but would love to check it from an expert).
example. If you are over 50 years old your lens which is used for accommodation for near distance will go stiff. Usually if we look at near objects we automatically accommodate to pushour far point to that thing. If you had no lens or it is not working anymore: +3 dpt of ADD. Reciprocal of that means 1/3 which means 0,33m or 33cm since 1/dpt is meter. To push your far point more to distance you need to take your ADD and reduce it. -> 1 dpt: 1/1 which means 1m.
Feel like nothing helps getting things under control. Tried different eye drops and been in IPL 5 times. Still getting inflammation 2 to 3 times a day. Help please 😭😭😭
I have nearsightedness on my left eye of -5.75 with axis of 010, cyl -0.75 and DIA of 14.5 and farsightedness on my right eye +0.50 with axis 189, cyl -2.25 and DIA of 14.5. Astigmatism in both my eyes. My glasses make it seem my one year is bigger than the other. Is there any other way around to making my glasses look even?
One way to achieve that in your situation would be to correct both of your eyes with contact lenses and wear glasses with 0 power on top of it. Or you could look into Ortho-K lenses. One Problem there would be that you might be out of range for those lenses because your high cylinder on the right. But you could try it. Else it's kinda rough to fix it since glasses who correct high - naturally come with reducing the size of the picture. Same the other way round.
Hi My name is Abdullah from Pakistan My right eye is damaged and the left one is -19 eye glasses no Should I go with the ICL surgery or wearing the high no glasses for just one eye plz give your suggestion Thank you!
I'm like your husband. I had bifocals, then trifocals and didn't like them, but got progressives and loved them. I remember when an astigmatism correction was first added to my prescription, the doc warned me to be careful with steps. I followed his advice and in a matter of days was totally comfortable with the new glasses.
I ordered progressive glasses on line and the part where the line would be if it were bifocals, was in the middle of my line of sight. They had me take a picture of myself with glasses on and they remade the glasses. Is there a way to get it right the first time? This is something that I have yet to see explained, and their explanation was less than helpful.
There you had to use a caculation which translate that which counts in the corneal vertex distance. There are usually Calculators online who can do that easily

Thank you so much for the convert minus to plus section at the end. I just got a new eye test and the new prescription was using the + instead of -. The numbers were very different and I thought my eyes must have changed a lot, but it turns out it's just written in a different form.
@@DoctorEyeHealth I have a further question regarding this conversion. Let's say my Sph is +1.50, Cyl is -3.50 and Axis 90, after the conversion, it becomes Sph -2.00, Cyl +3.50 and Axis 180. But since the Sph value changed from a positive value to a negative value, wouldn't that make me far-sighted in one form and near-sighted in the other form? But surely I can't be both far-sighted and near-sighted at the same time, so am I far-sighted or near-sighted in this case?

I was able to obtain 2 free eye exams. One from a private practice and one from the UCLA Mobile Eye Clinic that was at a local library one day. The private practice used all of the modern equipment, while the UCLA team used hand instruments. The private practice doctor was an optometrist and the UCLA doctor was an optomologist. Here are the measurements Private Practice = OD SPh +2.25 Cyl -.75 Ax 103 OS SPh +1.75 Cyl - .50 Ax 053 UCLA = OD Sph +1.75 Cyl DS OS Sph +1.50 Cyl +.50 Ax 155 Both NA +2.25 2019 Costco RX OD Sph +1.25. Cyl -.50 Ax 100 OS Sph +1.00 Cyl -.50 Ax. 044 NA +1.75 PAL ADD +2.00 I have only used readers and now need some help with distance. Before I buy glasses I want to find the correct RX. Not sure if there is a major difference, but would really appreciate your insights. Thanks
TY I have noticed about every four months my prescription needs to be changed but my insurance only pays for once a year. Do some people have acelerated changes? My near sightedness is going in reverse. I have gone backwards on it with each check up.
Hey thanks for asking! There can be some causes of a faster changing prescription. In a younger individual, I would be concerned about a condition called keratoconus - which is a progressive corneal disease that often causes frequent prescription changes. For people that are middle aged, the change in prescription could be related to early lens changes (the lens inside the eye begins to crystallize and this can change the power of the eye), which is very normal. in addition if someone had been over-minused in their glasses - they may experience this change to a faster degree as the power of the eye changes and the eye muscles cannot compensate as well. The one other major thing I would want to watch out for would be blood sugar changes such as with early uncontrolled diabetes. Higher blood sugars can cause a swelling of the lens inside the eye and can cause a shift in glasses prescriptions. Hope this helps.
@@DoctorEyeHealthI led a support group at hospital for 20 years for people with fibromyalgia and in myself and others noticed frequent eyeglass script changes happened. Thought maybe drug changes but seemed not on further research. Also the lupus support group I led few times had same question about eyeglass changes. Any ideas? . My degree in Health Ed retired now
Hello Dr Allen; Kudos and thumbs UP for a great tutorial for people who wear glasses to understand what it all means! As a licensed optician, I try to explain to my new wearers exactly what the doctor prescribed and how it's going to help. I wish your videos were available when I was starting my career (some 30+ years ago). It's quite possible I would have chosen optometry. I always enjoy seeing your new videos as well as old ones. I'm always trying to keep myself up-to-date. Thank you! -Mitch, Brooklyn, NY
Yeah, I am still not 100% sure why they use Plus vs Minus, I'm not sure if that's just an old custom that has never died or if its because they are in the mindset of removing tissue rather than applying a new lens in front of the eye. Either way, it all works out in the end.
@@DoctorEyeHealth ok thank you for reply. Not now, but maybe in 3 to 4 years, if there will be a treatment for eye floaters and doctors are working on it, I'll be happy 😁.
Thank you so much, I just got bifocals (and/or progressives) at 25 after never having more than maybe reading glasses as a kid 😭 It'd explain my horrible reading ability despite loving it, I have one axis at 10 and another at 75! So no wonder things felt blurred together lol! It's gotten almost constant in the last half a year in a few ways, so I'm excited to have some answers now.
I just got my eyes rechecked and need progressive lenses. My distance vision is not real bad but close up and midways is. I guess they'll give me a copy of my script when my glasses come and that they are working for me.
Hi Doc, a quick question, does astigmatism also have near and far sightedness? i.e. objects closeby might look blurry or objects far away might look blurry? Or does having astigmatism mean all objects might be blurry, if yes then why the signs(+,-) My prescription says -2 and -2.5 cylindrical does that mean I'll have to wear glasses 24*7 or only while looking at distant objects?
Does 050 in the axis field correspond to 50°? Im ordering lasses and my prescription says 050. On the glases website it lets you choose 0° up to 180° I think. I'm assuming 050 is 50° and not 5°
Hmmm. Perhaps that is another way to write Manifest Refraction (measured power) and the Final Refraction (Ordered Power?). In eye care, when someone does a subjective refraction (the better 1 or 2 test), the final result of the subjective component is not always what the doctor will prescribe. Because sometimes the subjective results would cause problems with the eyes, such as double vision, for example. That is a bit of a guess though, I have never heard of anyone writing Ordered Power and Measured Power. Can I ask what country you got the Prescription in? Perhaps its a regional thing.
Hey eye doctor when i was young like 7 years old i saw everything in 2x speed i siad it to my mom and brother but when i was playing games in phone it stopped is this a symptom or something?? It happened to me like 4or7 times im not joking i saw everything in 2x speed pls help me am i the only one but is it possible if you know?? I was sleeping on my grandfather car and i woke up i had a sick back then when i was in my grandfather car and i saw everything in 2x speed
I would LOVE to be a -5.5! I’m a -13 😐. Even with this eyesight, I’m thankful to God often that my vision can be corrected with contact lenses, but it’s so hard to find eyeglasses that I don’t dislike. I am also in the early stages of a cataract in my right eye. I’ll be trying to fight that with good/better nutrition. I feel certain God will help me with that. I’ve just recently found your channel. Keep up the good work! I’m learning so much. I’ll be praying you’ll be able to endure as long as God wants you to endure. 🙏🙂
I'll be praying for your eye health I am a -8 and -9 and can understand how difficult it can be. Thank God He has given men knowledge to make corrective glasses. He also heals and does what no man can do. Great video.
When a man @ an eye wear business took out my new glasses out of the case, he got a wow! The best and most expensive glasses I ever had! One insurance paid $100, my second insurance paid $100, and I paid $49.
Thanks Doctor, your videos over the years have been SO clutch for eyeglasses, Transitions and especially ordering prescription sunglasses! My new prescription at the bottom says: Active - Yes Usage - Multifocal The doctor said I wasn't getting progressive or bifocals, but it appears I am maybe? Idk. Thanks!
Hi, I would be curious tu know your opinion on Essilor Eyezen +. I’m in my late 20s and on my last prescription I had a facultative +0.75 on my prescription. A video on anti fatigue lenses would be great 😊 (I should receive my new glasses in a week, I hope those lenses really do help with headaches). Great video as always
Hey! Random question: Do you ever prescribe your patients “honeycomb lenses”? Someone I know got honeycomb lenses from their eye doctor “to help with myopia” (doctor’s words) and I was curious how the honeycombs actually help! I love this video btw. It’s quite helpful with my own glasses journey. Thank you!
I have a question: are blacklights bad for your eyes? I grew up loving blacklight posters and I have a blacklight in my bedroom that I use as somewhat like a nightlight. The bulb is not visible and it is pointed upward to light up my ceiling. It's only on while I'm getting ready for bed as ambient light. But could this be bad for my eyes if it's on a regular basis every night?
