is 20/50 vision good?

It's not ideal, but it's not horrid either.  20/50 means that you can see clearly at 20 feet what someone with 20/20 can see at 50 feet.

NO. JUST DO IT UNTIL YOU NEED GLASSES.\nYOU WILL BE FINE.

It happens very fast.  Most people see at20/20 almost immediately but some it takes longer.  It can take up to a year for your eyes to adjust and most people have at least some fluctuations in that year.  But most people have nearly perfect vision right away.

well i had a -4.25 in one eye and a -3.5 in the other and i had BAD vision, so you must be blind as a bat. Go get lasik surgery, i did. Best thing ever.

http://science.howstuffworks.com/question126.htm\n\n20/20 means that at 20 feet away, the person can see what a 'normal' person can see at 20 feet.  20/40 means that at 20 feet away, the person can see what a 'normal' person can see at 40 feet.  (Paraphrased from site.)\n\nNow:  not consulting the site anymore. . . .\n\nThe eye prescription is measuring something different, and you're missing part of it.  There should be minus signs or plus signs:\n\n-0.25 + 1.50 x 134\n\nThe first number is called the cylinder.  The second number is called the sphere, and the third number is called the axis.  If the first number is negative and the second number is positive, then the glasses are for a nearsighted person.  I'm not sure what the configuration is for a farsighted person.  My guess is that your friend is farsighted(?), or at least not very nearsighted at all.\n\nYou are trying to compare apples and oranges.  You need to know how well your friend sees on the 20/20 scale, or else you need to know your own eyeglass prescription in order to see who has the stronger prescription.  An optician told me that thicker glasses do not necessarily mean your vision is worse than the vision of someone else who does not have as strong a prescription as yours.\n\nThe defiinition of legal blindness includes the phrase "best corrected vision."  Neither of you seem to be anywhere near that threshold (20/200 in the better eye, best corrected vision).  But notice that visual acuity is measured on the 20/x scale and is not expressed in terms of sphere, cylinder or axis.  \n\nBy the way, my brother told me that the measurement for glasses (-13.75+0.75x010) is taken in diopters.  So if you're wondering minus 13.75 what, it's diopters.  And that was the prescription for my right eye at one time (I'm not sure what the latest prescription is).  The right eye is the worse eye, at least.  Oh, well.\n\nhttp://en.wikipedia.org/wiki/Diopter\n\nA dioptre, or diopter, is a measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in meters.\n\nAt any rate:  in order to make a fair comparison, you need to compare your prescription to your friend's prescription or your best corrected visual acuity to your friend's best corrected visual acuity.

Yes they can reduce the brightness and contrast level and set it to 40-50% of the maximum. Initialy you will not be comfertable but after few hours your eyes will adjust to it.

20:20 vision means that you can see an object from 20 feet that is supposed to be visible at 20 feet. 20:15 vision means that you can see an object from 20 feet that is supposed to be visible at a distance of 15 feet.

I think u should get better reading glasses to read from a good distance. If u r young, u may damage ur vision progressively by straining ur eye muscles,by reading from a close distance.

I had LASIK eye surgery about 4 years ago with no complications.  My vision improved to 20/15 and 20/20.  I would recommend it if you are a good candidate.  Look for a quality surgeon who has done hundreds if not thousands of these procedures and check their rate of complications.  My surgeon had a complications rate less than 1% so I felt fairly safe having it done.

I suggest you go for Zyoptix-100.It is far more advanced, accurate & safe as compared to Lasik.\n\nYou may be a good candidate if you: \n  \no Feel that spectacles/contact lenses are a nuisance in your job, sporting activities or personal life\no Suffer from the effect of scattered light (aberrations)\no Have been told that your pupils are too big, or your corneas too thin, for standard treatment\no Have healthy eyes, good general health and are not taking medication that affects the healing process\no Are older than 18 \n\nI had Zyoptix last year & got a 6/6 vision from a case of extreme Myopia! (I mean it when I say Extreme). My vision is better than my corrected vision before surgery. \n\nHowever if you have a mild case of Myopia then exercises & good diet can help you get 6/6 vision sans surgery, \n\nP.S In case you plan a vacation to Thailand or India in near future then thats the place to get this surgery done. Its very cheap & they use complete state of art faclities. It will cost you Appx $800 for the complete surgery & tests in India & $2000 in Thailand. \n\nI say Go for it!

Not normally unless you have a problem seeing at night.Especially when driving other than that, it is legal to drive a car with 20/40 eyesight with out wearing glasses.I know because that is what the people at the DMV told me.

I have the same problem, I just found out I need glasses for it, but also for distance and stigmatism.  Nice combo, basically I need bifocals at the age of 25. :(  But the doc did say the computer is bad for the eyes, so every 20 minutes, you should look 20 feet away and look at that place for 20 seconds. 20/20/20.  It is supposed to help your eyes refresh.  Sleeping a full night helps too, don't forget to blink, use drops if needed.  The problem with computer screens is that each tiny pixel in the screen is moving on its own, almost flickering.  We can't see it because the flicker and pixels are so so small, but the eye needs to use more energy to focus on that screen, thus damaging your eye sight.  Get glasses, computer glasses, they are supposed to help, I am waiting to buy mine because I don't have eye insurance in 2006, but will sign up for it in 2007.

I havent tried it but I have fitted people with ortho-k lenses before. To be honest I found it a bit hit and miss- about 40-50% of my patients liked it, the rest just couldn't get clear enough vision. It works best if you have a low myopic (short-sighted) prescription, and little or no astigmatism. The limit is -4.50D, and about -1.00D of astigmatism. \n\nThe effect DOESN'T work for life, you have to wear them every single night in order to be able to see clearly the next day. if you stop wearing them your eyes will go back to normal within a week or so.\n\nIf you're willing to persevere with it, and you can afford the non-refundable fitting fees, it's worth trying, in my opinion.

I had it done in 2003 for about $2400. Insurance did NOT cover it.\n\nHere's my bloggage from the time:\n\nhttp://www.xanga.com/home.aspx?user=stjnky&nextdate=4%2f6%2f2003+23%3a59%3a59.999\n\nI was 37 at the time. That's "gettin on up thar" in eyeball years, which means my prescription for nearsightedness had been stable for a good long time, which is a good thing in LASIKworld, but since I was approaching middle age, the warranty wouldn't be good for very long... meaning, LASIK may give you 20/20 vision *right now*, but your eyes are still likely to change as you get older and you *might* end up needing glasses again some day.\n\nI've been very happy with the results. The only downside is that, I guess since they are cutting through nerves in your cornea when they do this sort of thing, your eyes might end up being a little bit drier than they used to be (maybe you don't *feel* all the dust particles like you used to? I dunno.)\n\nOhyeah, and this year, at age 40, when I went for my eye exam, I was informed that my left eye is 20/20, but my right eye is 20/50.\n\nI still don't *need* glasses, but I find that it helps with night driving. The other interesting thing about LASIK and night vision is that, since your pupils get bigger in the dark, you're viewing things through more of the laser-scraped part of your cornea, so you're more likely to have slightly less-than-perfect vision at night. Have you ever heard about the "starbursts" some people report seeing around lights at night? It's probably due to that. I don't see starbursts, and the doc told me that's mostly a thing of the past as LASIK technology has improved over the years, but I do experience a bit of hard-to-describe distortion. It's not a *dealbreaker*, but the glasses *do* make it better.\n\n(Fun fact: note the monacle in the profile pic? That's for the 20/50 eye. :-)

Probably not.  There are no studies that have proven that it works.  A handful of the exercises are almost valid vision therapy techniques but they aren't going to improve your vision.  The rest of the exercises are really just plain silly.  Go ahead and try it if you really want to, but it will end up being a waste of your money and time.
