Cataracts Cause Foggy Vision
A cataract is the clouding of a normally clear lens of the eye. Vision with cataracts is similar to looking through a foggy window. Vision affected by cataracts can often make it difficult for the patient to do or see normal things, such as reading, driving a car at night, or seeing expression on faces. Cataracts develop quite slowly, and often do not affect vision early on. In addition to clouded vision, patients with cataracts may also experience sensitivity to light and glare, as well as double vision in a single eye, fading of colors, and frequently needed to change prescriptions for eyeglasses or contact lenses. As the cataract grows larger, it will cloud more and more of your vision field, continuing to distort the light that is passing through the eye’s lens.
How Cataracts Develop
Cataracts develop due to the patients age, or an injury that affects the tissues within the eye that makes up the eye’s lens. The eye’s lens is positions behind the iris, the colored portion of the eye. The lens purpose is to focus light that passes in the eye in order to produce clear, sharp images on the retina. A cataract will cause the lens to stop focusing the light, and rather scattering it as it passes through the lens. This is why vision becomes blurry for cataract patients. As the body ages, the lens in the eye becomes thicker and less flexible, causing cataract symptoms to become more severe and noticeable.
4 Types of Cataracts Treated in New Jersey
There are 4 different types of cataracts that we treat at Marano Eye Care. A nuclear cataract may cause temporary nearsightedness, which may help patients with tasks like reading or using the computer. Over time, the lens continues to cloud and develop a yellow tint, blocking light from making it to the retina. Cortical cataracts begins as a white, wedge shaped cloudiness on the outer edge of the lens, and will continue to extend to the center of the eye as it progresses. Patients suffering from cortical cataracts often have issues with glare. Posterior subcapsular cataracts begin as a small, cloudy area in the back of the lens. It’s positon directly interferes with light passing through the lens to the retina. Congenital cataracts are cataracts that patients are born with. They are often caused by the mother having an infection during the pregnancy, but can also be caused by conditions like myotonic dystrophy, galactosemia, Lowe’s syndrome, or rubella.
