New Glasses Same Prescription Dizzy
Can new reading glasses with stronger prescription for astigmatism deteriorate my sight when i take them off?
Bought new glasses with exact same prescription as last pair. Right eye has constant ache with new pair. Doc and optician can't figure out why.
Refraction: A cycloplegic refraction may disclose some hidden hyperopia that is one cause of prescriptions not working well. Furthermore, proper fitting, pupil centration, pantiscopic tilt, and base curve maintenance is helpful. Undiagnosed microtropias & astigmatism axis changes are other fatiguing or blurring symptoms discovered on examination. And of course something could be wrong with the lens grinding. ...Read more
Try dimestore: It sounds like mostly your have near vision issues. Were the lost glasses bifocals? With a distance correction you needed? If not you can buy $10 glasses and do very well by them. And if you just want something in the meanwhile, el cheapo glasses are not a major investment and can be used later as a back up. ...Read more
Different: They are different. Often the overall power will be similar or the same, but contact lenses require more specifications, such as the curvature of the lens as well as type of material. ...Read more
I have new poly lenses have same base curve as old lenses and same prescription, yet vision blurs toward the edges?
Lens quality: Some people have trouble with polycarbonate lenses leading to some distortion in their vision, but usually this is not a problem if they are made well. If you have never used poly before, this could be the problem. If the lenses are much wider that others you have had, this could be a problem even with the same curve. It could be a manufacturing error, so ask the vendor or prescriber to check them ...Read more
Used monovision contacts for years& now want improved clarity & less glare with night driving. Are bifocal contacts a good alternative & comfortable?
Night glares+starbursts worsened even after using artificial tears.Anti-glare glasses - no help.Eye power perfect.Not cataract/glaucoma. Cause/remedy?
Incipient cataract : Early lens changes typically cause glare and star bursts .However, at age 30 corneal pathology can cause visual symptoms. Tears are a treatment for dry eye but not a cure. Superficial punctuate keratitis seen in dry eye is rarely eliminated by artificial tears alone. Anti glare glasses may reduce visual symptoms due to ocular pathology but minimally. ...Read moreSee 1 more doctor answer
Can myopia improve? Went to new optometrist have new glasses with L-.5 R-2, vision problems. Before L-1 R-3, never vision problems or lot of headaches
Or worse...: Wearing contact lenses you got without a prescription puts you at risk for a very serious eye infection that could cause blindness. Contact lenses have to be fit to the eye based on the curvature of the cornea. The solution the contacts are bathed in also should be sterile, which may not be guaranteed in a non-prescription contact. ...Read more
Numbers game: Fitting cl is an art form as much as science. When the eyeglass refraction is placed in a cl if the number is large enough the strength of the contact may be different to cause good vision. The fit can also change the numbers. These are called "fudge factors'. The numbers are not as important as the ability to see wella nd comfortably. ...Read moreSee 2 more doctor answers
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
High index : Helps make lenses thinner, solution? To clean? Warm soap and water the best, dry with non scratch cloth. I like the sprays the optical stores have with soft cloth. ...Read more
