A cataract forms when the lens in the eye becomes cloudy and reduces visual clarity. The National Eye Institute (NEI) reports that the retina cannot receive a clear picture through the cataract, which results in blurry vision. There are a number...
Cataracts are small collections of protein that accumulate on the eye lens causing it to be cloudy and making it difficult to see. This difficulty affects distance vision and causes problems with glare. Cataracts develop slowly but as they...
Because of the potential developmental problems that their presence may cause, childhood cataracts should be removed as soon as possible. The presence of cataracts prevents the development of vision in the affected eye, but if the intervention is...
Congenital cataracts are a clouding of the natural lens of the eye that is present at birth or that develops shortly after birth. In most congenital cataracts, no specific cause for the cataract is found; however, congenital cataracts that occur...
A cataract is the clouding of the lens in the eye. This lens is responsible for the vision of an individual and is normally clear. A cataract can occur in one eye or in both, and it can also spread from one eye to the other. According to the...
Cataracts form when the lens covering the eye becomes cloudy. Age-related cataracts are most common. However, congenital cataracts may occur due to prenatal disease, toxicity or hereditary and often accompany other syndromes. Older children may...
A lens sits inside the front part of the eye, focusing light for vision. As a part of the aging process, this lens may gradually turn thick and yellow, a condition called a cataract. During an eye exam, the doctor may determine the presence of...
A cataract is a cloudy section on the eye lens. The National Eye Institute reports that by age 80, over 50 percent of Americans will have a cataract or have had surgery to remove a cataract. The typical American diet often lacks nutrients needed...
Your eye contains a structure called a lens. The lens is responsible for filtering the light that comes in as you look at objects. The light is then sent to the retina. The retina then sends the information to the brain in the form of nervous...
Cataracts, a clouding of the lens of the eye, develop for many reasons. There are several types of cataracts: nuclear cataracts, which form in the center of the lens and are most often associated with aging; posterior subcapsular cataracts (PSC),...
The natural lens inside the eye focuses light on the back of the eye, which, through an intricate process, converts to a visual image. With age, this lens will often grow thick and yellow, distorting vision, though some conditions cause this...
One of the many side effects of living a long life is the development of cataracts. Many people over 50 years of age have some form of the cloudy eye condition. Often an optometrist will notice the cataracts forming behind the lens in your annual...
Cataracts, clouding of the lens inside the eye that focuses images on the retina, are inescapable. According to ophthalmologist Charles Slonim of All About Vision, all people develop cataracts, if they live long enough. However, cataracts usually...
A subcapsular cataract forms beneath the posterior lens capsule of the eye. Cataracts impair your vision, making it increasingly difficult to see. Cataracts are not painful, and can usually be treated by surgically removing the clouded lens and...
The corticosteroid medication prednisolone--which is also sold as Pred Forte--is an ophthalmic medication that can be used to treat a variety of eye conditions, says the Macula Center. Because Pred Forte can reduce inflammation or irritation in...

There are several different eye defects. Some are present at birth while others develop over time due to aging or disease. In some cases, these problems can be easily corrected. If left untreated, however, some eye defects might lead to loss of...
Doctors define legal blindness as 20/200 vision or worse. The numbers mean that someone with perfect 20/20 vision can see objects from 200 feet; someone with 20/200 vision can only see objects from 20 feet. Some eye conditions may cause temporary...
The front of the eye holds a natural lens that helps direct light to the back of the eye for vision. As part of the natural aging process, the lens will gradually turn hard and yellow over many years, and this will eventually cause changes in...
A natural lens inside the eye directs light entering the eye, playing an important role in how well a person can see. The lens will gradually age, causing a decline in vision as the lens turns hard and yellow, a condition called a cataract. A...
A clouding of the natural lens of the eye is called a cataract. There are three types of age-related cataracts---nuclear, cortical and posterior subcapsular---that can develop as people get older, according to The Eye Digest. Each type of cataract...
Ominpred ophthalmic drops are steroid drops used in the eye to decrease or prevent inflammation. The active ingredient in Omnipred is prednisolone acetate. Omnipred is used to treat a number of ophthalmic conditions including infection and...
The natural lens sits near the front inner section of your eye, just behind the iris. Light entering your eye passes through the lens and the lens helps focus the light on the back of your eye. With age, the lens will harden and lose its...
Behind your iris you have a clear lens. As you age, the components of the lens break down and form clumps, resulting in a cloudy, hard lens, a condition known as a cataract. Cataracts cause vision changes, and the only way to restore vision...
