Lots of things!  Here are just a few:\n\n-Uncorrected refractive error (fixed with glasses or contacts)\n-Corneal swelling\n-Other corneal problems\n-Cataracts\n-Retinal problems\n\nIf you're experiencing blurry vision, it's important that you see your eye doctor so that you can find out the specific cause and what to do about it.

You know you need glasses when you start seeing things in a blur. Or you start getting heachaches if you read to much.\n\nOnly the optican can give you a diffinite answer though

To much of anything will affect something!\n\nWill it affect blindness in a good way or make you blind?\nDon't belief everything you hear.

Yes, it leads to blindness.  I can only see out of one eye now due to excessive consumption during my youth.  If only Yahoo Answers had existed then!

That's a little scary... blurred vision is a sign of REALLY high blood pressure.

Gaming can be very harsh on the eyes! The light from the screen causes a lot of damage to the eyes and it may end up being serious. To avoid more trouble try to limit your gaming time. I know that is hard to do, especially now that it is summer, but to save you vision, I'd calm it down a bit! Go play outside some more! I get Migraine headaches which are a lot like over exposure to iridescent light....you start seeing spots and you get really dizzy and light headed. Then a stomach ache follows along with a POUNDING headache. I lie down for awhile and drink a lot of juice and the spots usually fade away. I also take Tylenol or another form of medicine. I am not sure if this will help you or not, but it is worth a try. Good luck to you and your brother!

Glasses, contact lenses or Lasik. You did not cause the eye problem, you were born that way. You cannot make your eyes near or far sighted by reading in the dark, using the computer too much, etc

Bilberry is a wonderful remedy for blurred vision and night blindness but it should only be taken for limited periods of time because it can and will cause liver damage. Ask your health food store what other remedies will be good for you.

1)  One cause could be overactive parathyroid glands. These glands controls the calcium in the body.  Too much calcium can cause what some call gritty eyes. Usually one can decrease calcium intake, especially if you are taking calcium supplements with vitamin D.  \n2)  Untreated high blood pressure can cause this problem as well. If not treated fat and calcium can easily build up along the artery walls causing plaque. This causes you blood vessels to become stiff and narrow therefore blocking blood flow to major organs. Over time this could lead to.....\nHeart disease \nIrregular heart beats\nKidney failure.  \nEye damage \nStroke and others \n   Either way, if you are having a problem like this you should really speak with your doctor.  This can be very serious.\nGood Luck

Astigmatism\n\nWhat is astigmatism?\nAstigmatism occurs when the front surface of your eye (cornea) or the lens inside the eye is slightly irregular in shape, resulting in vision being blurred at all distances. Astigmatism is not a disease, but is actually a vision condition that is quite common.\n\nWhat causes astigmatism?\nWhen the front of your eye or the lens inside the eye is more oval than round, light does not focus properly on the back of your eye (retina). The causes of this irregular shape are unclear. In some cases, it may be hereditary or it may result from such factors as pressure of the eyelids on the cornea.\n\nHow common is astigmatism?\nMost people have some degree of astigmatism. However, only moderate to highly astigmatic eyes may need corrective lenses.\n\nWhat are signs/symptoms of astigmatism?\nPeople with severe astigmatism will usually have blurred or distorted vision. Those with mild astigmatism may experience headaches, eye strain, fatigue or blurred vision at certain distances.\n\nHow is astigmatism diagnosed?\nA comprehensive eye examination by your doctor of optometry will include tests for astigmatism.\n\nCan astigmatism by corrected?\nAlmost all levels of astigmatism can be optically corrected with properly prescribed and fitted eyeglasses or contact lenses.\n\nDoes astigmatism get progressively worse?\nAstigmatism may increase slowly. Regular optometric care can, however, help to insure that proper vision is maintained.\n\nHow will astigmatism affect my lifestyle?\nYou may have to adjust to wearing eyeglasses or contact lenses if you do not wear them now. Other than that, astigmatism probably will not significantly affect your lifestyle at all.\n\nFor more information, ask your optometrist.

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 was having them daily for a while about a year ago. At first I had no idea what was going on I thought I was going blind or something. The worst part about it is how fatigued you feel. It also causes serious issues with driving when you frequently have ocular migraines. I talked to an optometrist and found out extended amounts of physical activity can trigger an ocular migraine. I have since toned down my work out and haven't had an ocular migraine since.
