There are many kinds of eye problems, and you may familiar with some of them, or you have heard their name from your eye doctor when you having regular eye exam. Some of the eye problems are very common among people, so it is necessary for you to know more exactly about these eye disorders.

Nearsightedness, also called myopia, is the most common eye problem that often occurs among young people. As the name described, people with nearsightedness can only see things clearly that is close to them and have trouble in focusing on distant objects. This kind of eye problem is easily diagnosed by doing vision acuity examination. People can also realize they have the eye problem of nearsightedness when they are not able to see letters or characters that are far from their eyes at the period of their school age.

The common treatment for nearsightedness is wearing eyeglasses or contact lenses. Some of the patient may also choose laser eye surgeries to get rid of lenses. However, none of the treatment method can solve this problem thoroughly. The condition of nearsightedness will generally worsen as time goes by if special eye care is not carried out regularly.

Farsightedness is the opposite of nearsightedness. People with farsightedness, or called hyperopia, can see distant things clearly but can¡¯t focusing on nearby objects. In this condition, you may find the characters of the book just in front of you blurry. This kind of eye problem often occurs at birth and can pass to their children through gene.

The difference between presbyopia and farsightedness is that presbyopia is caused due to natural aging. The kind of eye problem are very common among people older than 40. It is also easy to recognize presbyopia through eye exam and it can be corrected by wearing reading glasses.
