Approximately 125 million people in the United States wear corrective lenses. These can be either eyeglasses or contact lenses. Some need correction from childhood on, but 70 percent of the corrective lens wearers are adults. Here are the most common eye problems people suffer from.
Nearsightedness
When your doctor says you are nearsighted it means you have condition where light that enters your eye focuses directly in front of the retina rather than on it. This makes it possible for you to see clearly close up, but at increasing amounts of blurriness the further away. This is also known as Myopia.
Farsightedness
To be farsighted or suffer from Hyperopia means that you can see at a distant clearly, but are less able to do the closer an item becomes. This occurs because the light entering the eye lands behind the retina. It is often caused by the cornea not being curved enough, an eye that is too short by having a lens sits back too far.
Astigmatism
When a cornea is curved irregularly, it is known as an astigmatism. The condition causes blurry vision and those who suffer from it who choose to wear contact lenses will typically need to use a special type made for the disorder.
Presbyopia
This is the term for aging eyes which naturally results in a gradual loss of vision. It typically begins around the age of 40 and is caused by a loss of flexibility in the eye lens. It causes headaches, blurred vision and the inability to see small print up close.
