Can Wearing A Weaker Prescription Damage Your Vision
Eye prescription is +0.25x-1.0. So my power is "+", but spherical equivalent is "-". Am i myopic or hyperopic? Is near or far vision better?
Depends...: +.25 is negligible, so you can say you're emmetropic. However you do have astigmatism, so you are astigmatic . Technically, you're hyperopic with astigmatism. With current data, i couldnt tell you whether near vision or distance vision is better, depends on whether you have presbyopia or not. If you don't have presybiopia, then they are equal. Hope that helps, but it can get confusing.... ...Read moreSee 1 more doctor answer
Counting fingers: A higher degree myopia at the -11 diopter level will not allow you to see the big, 20/400 e on the standard visual changes. The level below that is recorded as counting fingers at some distance (2 feet or 3 feet etc.). Remember that what counts is the corrected vision which should be normal when you wear your glasses or contact lenses. ...Read more
Presbyopia: Correcting for far vision allows the eyes to comfortably focus at distance. At your age, the ability of the eye to change focus begins to deteriorate and is called presbyopia. That's why you see so many people with bifocals where distance is corrected in the upper part and near vision helped in the lower part. ...Read more
How bad is my vision prescription: OD +1.00 -1.25X180 & OS +0.75 -1.75X167 Everywhere I go = a different response.I've heard mild,mod,severe.
Not too bad: You have astigmatism that is with the role axis. This means that your astigmatism is youthful which may correct it self with time as the lids get heavier with age. Your correction is mild-mod. Less than one diopter consider mild and 1-5 consider low-high moderate respectively ...Read moreSee 1 more doctor answer
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
Depends: Need to have more info, like your actual prescription, is it blurry for distance or close up or both, does it have bifocal, etc. Etc. Perhaps there was an error in your prescription and its not actually the same prescription. Also, it could be as simple as different shape and size of your lens. You really need to take it back to the provider and discuss your problem. ...Read more
Why is my vision blurry with my new contacts even though its the same prescription from last time?
Is it possible for you to correct vision to 20/20 also what is 20/40 can you express it as a prescription?
Yes mostly: If the optical and retinal elements of the eye are normal, then correction to 20/20 is the usual outcome with proper eyeglass correction. 20/40 is a level of vision two lines down from "normal" meaning a line of letters large enough that a person seeing 20/20 could read that line of print 40 feet away. The prescription depends on whether you are myopic, hyperopic or astigmatic. ...Read more
Should i be concerned if my vision prescription is -5.25. What does that stand for when you normally say/see 20/20. Does that mean 20/525?
Presciption number: Those are two different things, like how much you weigh compared to how fast you can run. Your glasses or contact lens presciption is measured in units called diopters. It is the power of the lens (how curved it is) required to correct your vision back to normal clarity, which is seeing at 20 feet what other normal balanced eyes can see at 20 feet. ...Read more
Depends: The cause of your decrease in vision needs to be identified before a solution can created. The most common cause of decreased vision is refractive error which can be corrected with glasses or contacts. If the decreased vision is from an eye health problem, other solutions maybe available. See your eye doctor. ...Read more
