Universal Trial Frame/ Compartments and adjustable settings 

Thank you, very helpful!

Great video. Thank you. I'm a bit confused with the high power lenses section. If someone was a high myope with astigmatism, are you saying we'd use 2 different spherical lenses and then the cylindrical lens in the 3rd compartment? Couldn't we just place the high minus lens in the 1st compartment and the cylindrical in the 2nd compartment? Thank you

Nice to See

Sir❤️

What is use of green red lens sir plz tell

Super sir😊😊, Thank you so much

Sir can u plz tell me one thing.. Recently I changed my prescription but when I see through my new glasses I feel binocular double vision... When I see through each of my eyes individually I see clearly with no double vision but when I see by opening both eyes at the same time i feel binocular double vision.. After that i tilt my glasses a bit and this removes my double vision..doctor saying it is due to new glasses.. It will take some time to adjust.. or is this due to pantoscopic tilt? What r ur views on this sir?
