Conditions of the eyes have been around as long as mankind has. With the technological improvements provided by science, individuals with eyesight issues were given the ability to see better than before. Eyeglasses are the standard technique to correct vision problems, even with surgical options available.

There are several parts to an eye. All of these pieces are set in places which promotes the exterior light to shine directly on the retina. The light that arrives on the eye\’s retina is decoded and the image provided to the brain, this is what gives vision. As the light travels to the retina there are many things that can prevent the light from reaching its destination properly.

The majority of visual problems have to do with the eyeball itself. When there are abnormalities in the shape of the eyeball, the alignment needed to properly shine the light to the retina is disturbed. The light then can fall short, go behind, or create many points on the retina causing poor eyesight. All of these situations have to do with the eyeball not being the perfect round shape it needs to be to deliver premium eyesight.

Approximately on quarter of the world has nearsightedness, or myopia. Nearsighted individuals are exactly that, they are able to focus on objects that are close to them, but things far away are a blur. Myopia is caused by an eyeball becoming stretched out in a lengthwise manner instead of being the round ball it should be. Another reason for this condition includes the cornea shape becoming to steep, which forces the light going to the retina to not reach it appropriately.

Farsighted people, or those with hyperopia, have the opposite problem from those with myopia. People who are farsighted are able to see things in the distance very clearly, however anything directly in front of them cannot be focused on. The eyeball in this scenario has become too short, or the cornea is flat which again hampers the ability of incoming light to reach its destination on the retina as it should.

Many people are aware of the effects of aging, vision is no different. An age related vision condition in which the eye muscles weaken or the lens of the eye hardens causing a loss of vision to things close to the individual is termed presbyopia. Most people begin to see the effects of presbyopia in their 40\’s.

When the eyeball becomes the shape of a football and results in multiple points of focus on the retina it is called astigmatism. Astigmatism usually results in a total blurring of the vision both near and far. Occasionally astigmatism can all develop of myopia, hyperopia, and presbyopia which makes vision correction more difficult. Many times astigmatism can be mistaken for another disorder if it manifests as typical nearsightedness or farsightedness.

The best correction treatment for refractive disorders is to use eyeglasses. These therapeutic instruments are being used by the majority of the population which has turned them into a fashion accessory. In addition to eyeglasses, current medicine can offer surgical options to some suffering with vision issues.
