Excuse my ignorance. You don't have to be an optometrist to work in this field? Being an optician is something separate and doesn't require an expensive optometry degree?
Correct. In the US optician means something different than it does in many other parts of the world. Opticians here only make glasses, adjust glasses, repair glasses etc. Depending on the state little or no education requirements.
My shop says it uses "Industry standard tools" and I have disagreed about that since day one. But that's all they can get for the masses. Also, panel shops I worked in said they used industry standard too. And I disagreed then. A Philips screwdriver can not even get close to properly torque a Posidrive screw! Look at the screw-head imprint. Not a phillips! Now I have seen this video about a bit driver scraping the sides of the countersunk pocket of the flathead screw and I said Woah!-- Driver is too Wide! My shop supplies "Industy standard flip flop flatheads of 1.6 and 2.2 mm. That is not industry standard for our age. Using 1.6mm has not enough surface for good torque contact of a 2.0mm, and 2.2, that's why the bit scrapes the sides, if you even get to bite the sloted... I've seen people dig it out to get the slotted head to just bite. SMH. So. There was once an industry the 60's but now, we use Metric screw heads and threads. it's not a mixed bag. The (non)reasoning follows. Our Dads industial days they used flathead 1/16 and 3/32" imperial slotted screws and threads. Europe always used Metric. Now we are buying frames from china in this Metric World. We are needing tools for Flathead 1.5, 2.0 and 3 mm slotted head screws to work with (Same goes for philips). Now, 1/16 inch equates to 1.6 mm. 3/32 inch equates to 2.2 mm. That is all we have that we can buy. That is not even close. Then all the suppliers say "Yes we also sell metric equivalent bits, 1.6 and 2.2mm" Not trying to be close to the 1.5, 2.0 and 3.0mm standard we need today. So the "Industry Standard" taught us to Not to try to keep up, much less retool. The 1.6 and 2.2 mm only choice unless you get a graduated metric set (not an inside supply part) that has no interchangeable tips... I buy my own metric from WIHA and still get questioned about "Why, we give the tools you need" ... Told "A screwdriver's a screwdriver..." and get short with me. My shop does not care about frame waste or My feelings. (I have every colour Sharpie too, I hate shiners on my frames screwheads and of the ones others have sent my way. I see it, it's mine. I'll change out Gold Rayban's from replaced SS screws back to golds... even match the plus minus heads. I would have hated those if they were mine.
I’m training as an optician and the amount of times I have to say no is a lot. Lots of times people try to pick frames that don’t fit. I don’t let them buy those frames and at times people have become upset I won’t let them pick a frame that does not fit. Most of the time though, people are grateful for the help.
- 25.00 is extremely high and requires specialty work. Yes you would use high-index but also some specialty surfacing techniques as well. Most likely a lenticular perhaps with a bi-convex. Please email me through the OpticianWorks website and I can connect you with the lab who would know best.
@@MahmoudFayez-v7m Retail costs here in the US for something like that in single vision (lenses only) would be around $300 - $600. We are a wholesale lab not a retail store so hard for me to be exact.
John my optician has suggested office progressive but it's pricey and suggests I go for single lens if cost is an issue. I am wearing progressive for daily wear. Is this good advice?
Depending on your work situation a single vision is always the best choice. If you really sit staring at a computer all day go with SV. If you have a slightly more demanding role where you move around an office or cubicle you might want to consider the office lens. Video attached.
Hola Mr. K, tenia tiempo que no veia tus videos pero aqui estoy otra vez, tengo muchos anos de Optician, pero creeme, siempre se aprende algo...y de ti e aprendido mucho...🤓👍...
its true progressive cant do everything perfectly. i am about to get my second progressive and this time from zeiss and my optician suggested smaller frames for index 1.67. what he told me was zeiss progression is much better and distortion wont be as much. i love my current glasses just that right eye may have increase powers. i adapted to my first almost immediately. my question is it true what my optician said that better brands of lens provide better comfort?
Without knowing much more all I'll say is, "there isn't any magic pixie dust." Zeiss makes some great lenses and you should do fine. As to "much better and distortion won't be as much." Maybe, maybe not, probably. I'm guessing your power is quite high - hence the 1.67 and the advice on using a small frame so it sounds like your optician may know what they are doing.
@@LaramyKOptical thank you kindly for your reply. 1.50-0.5 R 2.5 0.75 L still under 3.0 limit I suppose. He suggested 1.5 index if I insisted on a larger frame or if my power was higher than 3.0. his logic was to keep the overall weight of the spectacles light. Plus 1.67 index was much cheaper to consider over the 1.5 index sir
@@guardian7keys 1.5? CR-39 or Trivex? Sounds like maybe things are bit backwards? Unless you are talking about the dinner plate special sized frames weight differences will be negligible. Trivex is great. CR-39 is cheap but thick. 1.67 is OK for powers like yours but a tad of overkill.
@@LaramyKOptical I am not sure if the plastic is c39 or trivex sir. 1.67 was the thickest in the Zeiss light progressive 2 series. Its all really confusing 😭 I am really looking for an all rounder progressive. My optician has suggested a reading or computer pair. But asked to try the zeiss first if it fits for me day to day activities.
@@guardian7keys Even with the best progressive possible an additional pair of single vision for computer distance is a wonderful thing. The rest sounds like a misunderstanding - I'm not sure how they could possibly know how thick the lens might be when finished (unless they are surfacing and finishing it there) and 1.67 should be thinner than any 1.5 not thicker - that is the entire point of a higher index lens.
@@LaramyKOptical no this comment was just for my personal reference nothing else. Excellent video. My intermediate vision clarity both in progressive and bifocal is poor. Therefore now I have to choose between office lens and single vision. Slightly difficult call for me to finalize for home computer use.
This is still not understood by optical sales teams(many) and properly communicated to Consumers.. Also pitch high index materials for standard Rx. And charge high pice. Thanks for bringing the fact to light.
doesnt seem like its easy or straightforward to purchase a single pair of lenses from the website. but im interested in trying them. i sometimes get pain behind my eyes when im working and driving at night. i think my left eye gets it worse because im on the left driver side (USA) and i think the headlights of oncoming traffic hit my left eye a bit more intensely. its like a pressure behind my eyes, sometimes it hurts or causes a headache ;(
I called McCray and was unable to source the jig/fixture. The customer service representative could not tell me exactly what it was called."Not looking to reinvent the wheel if it already exists ."😅 Would like to source the fixture any suggestions?
I would have to say, no. I doubt you can manually decenter for PD and then expect the edger to take care of an OC height. I guess it could work but you would have to experiment with the edger. The basics shown in the video assume no OC height = 1/2 the B. And OC heights are for higher powers and should be kept to around 0 - 5mm. If you need much more you have the wrong frame.
Hi - thank you for this refresher. As an Optom, I use resultant prism all the time. It's a shame that most DOs don't understand the notation. My question has to do with how to add two resultant prisms together. Ditto subtraction. Say I have RE 2.36@334 and wish to add 1.09@ 321 to it, is there a calculation that does it simply please? Thank you.
I'm not sure it answers your question. If not it might at least point you in the right direction for solving it yourself. Those two videos are my sum total of knowledge on the subject. John
On the practical exam practice test it’s asking for intermediate and near. I’ve always used 40 for near and infinity for distance what is intermediate? I can’t get any question right 😢
The pupilometer dial has 30,35,40,50,65,100,200 infinity. So I'd say 65 would be a likely intermediate. We never used the dial just intermediate -2 and near -4. Wish I could be more help. Must be a practice exam for prep? Answer it until you get it right and then you'll know?
Hi!! This is unrelated to this video but I was wondering if you could do a video on how to fix 180 degree temples on children’s glasses. I have a pair and I’ve never worked on something like this, it looks like it can be fixed but I’m having a hard time. Am I missing a tool? Am I going about it wrong? It’s a screw that’s missing please help
If it helps for prism, the way I understand it is; PT PD is Right eye or (OD) 31mm and it was received at 33mm, that 31-33= 2mm BO (base out) because the received PD is larger than the PT PD. In the OD the prescription is a minus lens (-) when the RX is minus we change the base to the opposite direction, in this case meaning BI. If the RX was in a plus lens (+), then we keep the same base direction meaning that our base would stay as BO (base out). Hope this helps! Great videos, I am refreshing my memory for my BOARDS!
Guys if it helps, the way I think about how to know what type of prism it is: PT PD is at 67 and Glasses were made at 60, so we know that is BI because the glasses came with a smaller PD than the one, they were supposed to have. Then I looked at my prescription in the eye that am I working on. If is a (+) plus lens, then the prism stays in the same direction BI. If is a (-) minus lens, then the prim is the opposite, in this case BO. Hope this helps! The videos are great and very helpful now that I am getting ready for my BOARDS and needed a refresher.
I'm not really sure how that approach is any easier/simpler than learning the rules and drawing things out - BUT - heck if it works for you keep doing it.
Trivex is WONDERFUL! Great optics, lightweight, great for drill mounts. It is what I use in all my glasses, family glasses, friends glasses. If you have a choice between Trivex and poly always go with Trivex. See the other videos about material choices.
speaking of minimum seg height (18), i also require that the patient has at least 9 mm from the fitting cross / center to the top of the frame for distance viewing (10 or more is ideal, 9 still ok in my experience). whether or not the frame has nosepads makes a huge difference in deciding if these factors will cause me to reject the frame, due to adjustability or lack thereof. NB (LDO)
Been wearing progressives for about 2 months -- took a few weeks to get used to them. I do a lot of work on my computer and my neck is absolutely killing me (from the constant moving my head to focus on different parts of the screen). I'm going back to dedicated reader glasses for working, and will keep the progressives when doing anything else (watching TV, being outside, driving, etc).
Hi, I am an optician from pakistan. I have a question that a person who have a prescription that, L eye 3 prism @90, and 3 prism @ 180. What is that mean, with DP os is +5.50/+1.00 80
Thank you for taking the concepts and simplifying them. I have been watching your videos for a year and learned how to do my optician job better and prepared for the ABO. You are a gem and I really enjoyed the process and have learned sooo much!!!
What is the outside temperature in this demonstration. As you know, temps have a lot to do with the efficacy of photochromic activations as well as exposure to sun
If I recall correctly it would all have been in the 70's inside and out. I'm literally sitting here waiting for a sunny day to shoot a new video on IOT's latest version of NeoChrome. So please stand by.
