Optometry: Wore progressive lenses for years and then switched to single lens distance glasses for years. Cannot get used to new progressives. Why?

Optometry: Wore progressive lenses for years and then switched to single lens distance glasses for years. Cannot get used to new progressives. Why?

Confusing: Your question is confusing-- if you switches from a progressive to a single distance lens you would not have a reading power and near objects may be blurred. More lokely is that you have recdieved a progressive lens with more reading power,restricting your side to side vision. A teardrop shape bottom is important to capture all the reading power.Brands do make a difference. I like Zeiss/varilux ...Read more

I have progressive lenses. Looking to get prescription sunglasses. Is it ok to get single vision lenses in those b/c i only need them for distance?

I have progressive lenses. Looking to get prescription sunglasses. Is it ok to get single vision lenses in those b/c i only need them for distance?

Not a problem: It is unclear to me why at age 19 that you were prescribed progressive lenses since your powers of accomodation (near vision) should be normal. Go ahead and get the sunglasses with single vision lenses which should perfectly address your needs near and far. ...Read more

Use progressive lenses and monovision contacts . When I cover one eye objects appear larger in one eye than the other. Why is that?

Use progressive lenses and monovision contacts . When I cover one eye objects appear larger in one eye than the other. Why is that?

Accidental telescope: The eye with the more minus contact lens sees the larger image because a minus lens acts as an eyepiece in a Galilean telescope, while the progressive bifocals act as the objective lens. This is of theoretical, but little practical value clinically. Either switch to bifocal contact lenses or correct both eyes for distance with the lenses and use over-the counter readers. Aniseikonia fixed. ...Read more

I discarded 2 pairs of high cost progressive eyeglass lenses due to inaccurate astigmatism results by 2 optometrists. The 3rd one got it right. Why?

I discarded 2 pairs of high cost progressive eyeglass lenses due to inaccurate astigmatism results by 2 optometrists. The 3rd one got it right. Why?

3rd Times a charm: Is the question, why did the 3rd one get it right? That could be that the 3rd one got it right because he did a better job-Or that he saw the other 2's mistakes & did not repeat those mistakes. If you are asking why the other 2 optoms gave you glasses that your eyes were not comfortable with then it could be a few reasons. If you are asking why you discarded 2 pairs of glasses, that is a good "?" ...Read more

Why can't they make a progressive eye glass lens where the vision for intermediate and reading is wider... Even to the edge of the frame?

Not optically done: Progressive lenses have two issues: 1) giving a continuous grind to allow for several distances of clear vision and 2) cosmetic optics so that the continuous grind is not evident. They could make a lens with a much larger optic as you are hoping for but this would produce obvious optical distortions that would make the lens look odd and would not reach the edge of the lens anyway. ...Read more

I'm going to try multifocal contact lenses. Should my quality of vision with these be the same as progressive glasses?

I'm going to try multifocal contact lenses. Should my quality of vision with these be the same as progressive glasses?

No: The vision with glasses is better. However many people successfully wear multi-focal contact lenses. Be patient and work with your eye doctor. Th multi-focals generally require more time to adapt and more adjustments than other types of contact lenses. ...Read more

After wear progressive glasses 5 hrs. at computer I see ghost images vertically, 2 traffic lights, road signs. W/contact lens OK. Dr doesn't know why.

After wear progressive glasses 5 hrs. at computer I see ghost images vertically, 2 traffic lights, road signs. W/contact lens OK. Dr doesn't know why.

Accommodative spasm: Take more frequent breaks from near work: Rule of three "20's" Every 20 minutes, remove glasses, look at object st least 20 feet away, for at least 20 seconds. Consider using "single vision "drug store" reading glasses, not progressives, at computer. They are very inexpensive, ~ $10 at flea market. Start at +1.50, bring magazine to test at normal reading distance and go up or down in powers ...Read more

What are the best lenses for strabismus? (exo) are toric or multifocals better? Doctor said there can't be surgery at this stage. Also, are progressive/bifocal glasses better than single vision?

What are the best lenses for strabismus? (exo) are toric or multifocals better? Doctor said there can't be surgery at this stage. Also, are progressive/bifocal glasses better than single vision?

Lenses may not help: If you have a lazy eye, no lens will "fix" it. However, any lens that gets you to your best corrected vision will help but i usually recommend staying away from multifocals in lazy eyes. If you still have a muscle problem--this should be addressed by a strabismus surgeon. ...Read more
