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
Depends: Most standard lenses are readily available up to -12. Higher powers are available by special order. ...Read more
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
Can prescription glasses worn all the time with wrong strength have -ve impact i.e make eye sight worse for a 4 yrs old? He is near sighted.
I have high myopia: -7.5, - 1.75 R; -8.0, -2.0 L is my specs prescription. My contacts prescription however is approx -1 stronger! Is this normal?
What do the numbers on my contact prescription mean in terms of how bad my myopia is? Is -3.75 and -3.50 a mild, moderate or worse degree of myopia?
Mild-mod: Not taht bad, its a mild to mod myopia. ...Read more
Depends: In many people, there will be no symptoms. In others, eye fatigue will occur, especially with close work. ...Read more
Can't answer: An eyeglasses prescription is a complex set of measurements. There are several combinations of these measurements that correct someone who is 20/200. ...Read more
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 was diagnosed with myopia and in my new glasses prescription there is no minus in front the number, are there any mistake?
Yes: This is probably a sign that was not placed there. Is there a plus sign before the numbers. Check with the eye doctor that gave you the prescription! ...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.
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
Please help! What happens if my glasses/lenses' prescription is slightly higher than my real myopia? Will that make my eyes worse?
I have myopia and astigmatism and now iam wearing prescription glasses can I use this glasses when reading books or in computer. Thank u?
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?
42 year old with a -0.75 eye prescription. Will I still need reading glasses at some point? Or will this level of myopia cancel it out?
You'll need them: Probably in another 4-5 years.Get a more detailed answer ›
Do all toric contacts correct both astigmatism and myopia? Some of them say they are for astigmatism and don't mention 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
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
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
Which vision correction surgery method would work for my nearsightedness and astigmatism? I'm tired of wearing contacts, and I'm curious about the different types of vision correction that are available. Is there one kind of surgery that can correct both
Which laser eye surgery correct both my nearsightedness and astigmatism? Do either of the popular types of laser eye surgery, lasik or prk, fix these issues so that i'll have 20/20 vision or close to it? I can't wear contacts; I've worn glasses since I wa
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
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
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
I play a lot of video games and I'm kinda near sighted. Anyway to get far sighted naturally? How?
I ve near sighted (myopic) vision and I wear glasses for that but should I wear these glasses while reading?
Easily: By definition, if you are nearsighted then without corrective lenses you can see well up close but not in the distance. For example you can read small print on a page if you hold it close, but you can't see road signs or text on a tv across the room. ...Read more
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
