The eyes are a very important part of the human body, as they control vision. The eyes function just like a photography camera. As light enters into the eyes, it passes through what is called the cornea. The light then goes to the aqueous humor, which is the fluid that sits in front of the eye. Finally, the light goes to the pupil and the lens. The light causes the lens to bend and the light allows the eye to focus on the lining in the back of the eye, called the retina. The retina is very important as these cells have an optic nerve that sends messages to the brain and allows them to be processed. When a cataract occurs, it interrupts this process and the vision is disturbed.
A cataract is a protein material that is like a piece of skin that grows over the eye. It makes the vision cloudy and it prohibits the light from passing through the lenses. While all vision is not lost, it usually causes everything to be blurry. New lens cells are constantly forming on the outside of the lens. When older cells become compacted into the center, this is what causes a cataract.
There are several types of cataracts. The age-related cataracts develop as a normal part of the aging process. When dealing with congenital cataracts, these are ones that a child is born with. They can also develop from an infection or from injury. Secondary cataracts are ones that form due to medical issues. Those who have diabetes or have taken certain drugs may find themselves faced with this condition. The final type of cataract is known as traumatic, and these form on the eye after any kind of injury involving the eye area.
A cataract develops very slowly, they don’t show up overnight. The first sign is usually a person will notice that they have blocked light in their vision. Also, it is not uncommon for people to notice that they have a progressive nearsightedness and no longer have the need for reading glasses. Driving may be a real issue, especially at night when the lights have a glare from them. Double vision is another common symptom or the need for glasses to be increased.
A doctor will give an examination and test the vision. They will dilate the pupil area and examine the lens of the eyes; it is here where the cataract can be clearly seen. To remove the cataracts is not as evasive of a procedure as it once was. Thanks to the developments in lasers, these procedures can be done outpatient and take just a few minutes. Abilene Eye Institute is helping people get rid of cataracts and helping with other conditions of the eyes. Since vision is the most precious of the senses, it is important to take care of any issues as soon as they arise.
