What is the highest near sighted prescription for your contacts?

What is the highest near sighted prescription for your contacts?

Very high: Premade contacts occur up to about -16.00 diopters. But if you have a greater power need, then a gas permeable lens can be made to any power needed. So there is no highest prescription for any power. ...Read more

Buying pre-prescribed eyeglasses for nearsightedness, do I need a prescription?

Buying pre-prescribed eyeglasses for nearsightedness, do I need a prescription?

Depends: Over the counter reading glasses assume both eyes are the same without astigmatic error. This is rarely the case. Frames are also designed for the "average" face and cannot be custom fit to your interpupillary distance. That being sain, there is no harm in trying a pair to see if they work for you. ...Read more

I'm 46 yo with pathologic myopia. Recently my prescription jumped from -17 to -20! any treatment to stop/reverse it?

I'm 46 yo with pathologic myopia. Recently my prescription jumped from -17 to -20! any treatment to stop/reverse it?

Malignant myopia: Is associated with progressive increase in nearsighted correction, sometimes to a level that you are experiencing. Usually, the prescription doesn't progress that much at your age. You should have your ophthalmologist evaluate you to make sure that you're not developing cataracts. They can also cause progressive myopic changes. ...Read more

I have a corrective lens prescription for myopia. How do I derive the intermediate (computer) distance from a D.V. prescription?

Add a little plus: In most cases the prescription will be for distance indicating some degree of minus power. To adjust for computer screen distance, add +1.25 to this power and that usually works. Note however, that the pupillary distance (the space between each eye) is set for distance viewing (usually 57-63 mm) and needs to be adjusted closer for viewing of a video screen. ...Read more

What to do if I'm 46 yo with pathologic myopia. Recently my prescription jumped from -17 to -20! can any treatment stop/reverse it?

Pathologic Myopia: This high degree of myopia is generally because of two reasons. A staphyloma in the retina which is an outpouching in the back, making the eye effectively longer, or keratoconus, a disorder in the cornea. A rigid gas permeable contact lens can be used or, if you qualify, an intraocular contact lens (ICL) can be placed. You would need to see an ophthalmologist that has experience with placing ICLs. ...Read more

What level of myopia would cancel the need for reading glasses? What age would a -1.00 prescription normally need readers? I take glasses off to read.

Few more years: At your age a -1.00 rx is good for reading when you have your glasses off. In another 5-7 years you might feel the need for a mild prescription even when your glasses are off. If you keep your glasses on to read, you'll probably begin to have some problems pretty soon. ...Read more

Could using updated/strengthened prescription glasses encourage progression of myopia?

No definitely not.: Current glass correction will only make you see better, to say it will cause a worsening of myopia means that that source of information does not know the principles of optics. Be carefully these sources have an alternate agenda to get money from you for a unproven program. ...Read more

I currently am at a -5.5 prescription at 19 (also male) and I'm still encountering a progression in worsening vision. Does this mean I have pathological myopia?

I currently am at a -5.5 prescription at 19 (also male) and I'm still encountering a progression in worsening vision. Does this mean I have pathological myopia?

Pathologic myopia: Pathologic or degenerative myopia is high myopia (-6.00D), also known as near-sightedness, with any posterior myopia-specific pathology from axial elongation (meaning changes inside the eye/the retina due to the bigger eyeball length). Excessive computer work, near work is causing an epidemic of myopia & pathologic myopia. See: http://eyedoc2020.blogspot. Com/2016/11/pathologic-myopia-or-degenerati ...Read more

New optometrist changed myopia prescription to astigmatism prescription and have had a migraine ever since. My old glasses don't do that. What happened?

New optometrist changed myopia prescription to astigmatism prescription and have had a migraine ever since. My old glasses don't do that. What happened?

Go back to optom.: Glasses are sometimes made incorrectly.
Other times the refraction (measurements) are done incorrectly.
You shouldn't be having headaches from a prescription which is supposedly 'better' than the old one.
Go back to the optometrist. ...Read more

Within 1 week: Assuming your lasik surgery went well, you can go out and get computer glasses. If you are concerned your prescription might still change, get a temporary pair of over-the-counter glasses to start you off. ...Read more

Is it possible for contacts to slow or control nearsightedness?

Orthokeratology: Is a pseudoscience devoted to doing just this. As a corneal specialist I find this to be an absolutely terrible and dangerous practice. ...Read more

Do contacts lenses slow the progression of or even decrease nearsightedness?

Not really: Many practitioners will tell people in their twenties, when myopia naturally slows anyway, that if they fit them with their "special" (frequently expensive) lens, that the condition will not progress. Putting a piece of plastic on the eye surface will not change its evolution into whatever power it will end up at. ...Read more

Can some contacts actually slow or control nearsightedness?

Yes: Rigid contact lenses can stabilize the cornea and reduce the progression of nearsightedness. That being said, they are rarely prescribed for this purpose. Most people wear the contacts they like and change the prescription as their eyes change. ...Read more

What percent of the us population are near-sighted?

About 40%: There are many breakdowns of this statistic. Children rarely are near sighted (myopic) as it usually starts in the teen years. Population subgroups vary also for instance asians have a higher incidence of myopia. Fortunately this is mostly correctable and can be done with lasik as well. ...Read more

Is it possible to be near-sighted in only one of your eyes?

Is it possible to be near-sighted in only one of your eyes?

Yes: Eyes (like feet) can be of different size and different eyeglass needs. Many have some degree of near-signtedness in one eye while the other needs nothing. Occasionally the nearsightedness of one eye is extreme and it may actually lose vision due to this (termed amblyopia). See your ophthalmologist to sort this out. ...Read more

Is it possible to buy eyeglasses and then have the frames changed to near-sighted ones?

Is it possible to buy eyeglasses and then have the frames changed to near-sighted ones?

Change the glass: Frames are just to hold the corrective lenses in place, so changing the frame will have no effect on the power. If you find an eyeglass frame you like, an optical shop - with the proper prescription - can replace the old lenses with your prescription to fit the frames you like. ...Read more

Why can't I get near sighted eyeglasses in stores?

Why can't I get near sighted eyeglasses in stores?

Too many options: Stores carry reading glasses because these come in discrete steps with few possibilities. An inventory of near sighted glasses would require hundreds of eyeglasses to cover the most common powers, and that does not include the need for astigmatism correction. So glasses for these needs are fabricated through optical shops due to this complexity. ...Read more
