Eyes are among the most sensitive organs in the body. Thus, they must be properly cared for to keep them in good condition. Good eyesight is responsible for making everyday activities manageable. Without it, people would be literally left in the dark. That is why people try to correct simple eye problems, such as astigmatism, in its early stage to avoid more serious problems in the future.
For older people, there are more critical eye problems than astigmatism. Most elderly people have trouble seeing because their eyes are unable to focus. They also complain about floaters distracting their view, as well as a hazy vision. When constant fogging blocks their view, it might be a case of cataracts.
A cataract causes the eye’s natural lens to cloud. The eye’s lens is composed of protein and water. The protein has a specific arrangement that preserves the lens’ clarity and allows light to traverse it. As people grow older, protein inside the eyes clumps together, forming a mass. This mass becomes the hazy view that people see—the cataract. Over time, the cataract can grow larger and block more areas of the lens, making it even harder to see.
A cloudy view is not the only symptom of cataract. Some people cannot tolerate the sun, or even a lamp, because it’s too bright for them. For instance, lights directed to a person, such as a headlight, appear brighter than they normally do. Colors may seem duller than usual too. When these symptoms are experienced, visit a doctor immediately for an eye exam Houston offers.
There are different types of cataracts. Having an eye exam Houston will help determine what kind a patient is experiencing. A subscapular affects the rear of the lens. People suffering from diabetes are more vulnerable to this type of cataract. Nuclear cataract occurs in the nucleus of the lens. This generally happens due to aging.
Cortical cataract takes place in the lens cortex, which surrounds the nucleus. It triggers white opacity to block eyesight starting from the lens’ periphery to the center. In order to retain a complete and healthy vision, visit an eye exam Houston clinic for prescription glasses. But if the cataract gets worse, eye surgery will be necessary.
