A cataract is a clouding of the normally clear lens of your eye. For people who have cataract, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataract can make it more difficult to read, drive a car (especially at night) or see the expression on a friend's face. Cataract often develops slowly and doesn't disturb your eyesight early on. But with time, cataract will eventually interfere with your vision.
At first, stronger lighting and eyeglasses can help you deal with cataracts. But if impaired vision interferes with your usual activities, you might need cataract surgery. Fortunately, cataract surgery is generally a safe, effective procedure.
Causes of Cataracts: Cataracts happens when protein builds up on the lens of your eye, making it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. New lens cells form on the outside of the lens, and the older cells are compacted into the center of the lens, forming the cataract.
Types of cataract include:
- Age-related cataract: These cataracts form because of of aging.
- Congenital Cataract: Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born, or they may develop during childhood.
- Secondary Cataract: These develop as a result of other medical conditions, like diabetes, or exposure to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation.
- Traumatic cataract: These form after an injury to the eye.
Other thing that can raise your risk of getting cataract includes cigarette smoke, air pollution and heavy drinking.
Symptoms of Cataracts:
- Clouded, blurred or dim vision
- Increasing difficulty with vision at night
- Sensitivity to light and glare
- Seeing 'halos' around lights
- Frequent changes in eyeglass or contact lens prescription
- Fading or yellowing of colors
- Double vision in a single eye
- Surgery: Surgical removal of a cataract is the first and foremost way of dealing with it. The clouded lens is usually removed and is then replaced with a new, artificial lens that will give you improved vision.
- Visual Aids: These aids include lens and eye glasses that will help you see better after the surgery. Cataract glasses usually come in thick and heavy structure. Also, intraocular lens and contact lens can be used by adults who have undergone the surgery. The constant need to remove, clean and re apply makes it inappropriate for young children. Low vision aids can be used before surgery as well, to ensure that best use of the remaining vision is made with the help of video enlargement software and other adaptive means.
- Medication: The use of eye drops and other medication can also help in improving vision without the actual surgery for cataract removal. This is a short term solution that can be prescribed by the ophthalmologist whom you visit. The doctor will usually study the extent of the damage and prescribe this kind of medication for cases that are mild. But finally, surgery will have to be carried out as the progression of the cataract is guaranteed in all cases.
- Soft Lighting: At home and at work, you can make use of soft lighting so that there is less pressure on the eye lens. Also, soft lighting will help you see better without the glare blocking your vision in case of the presence of a cataract.
- Avoiding Intricate Work: One must avoid hobbies and work that require unblinking attention or many hours as this can put a strain on the eyes and even lead to severe headaches. This includes painting, embroidery and carving related activities.
Dealing with a cataract is a matter of going in for surgery and making certain lifestyle changes to avoid injuries due to impaired vision.

A cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.
Types of cataracts:
- Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
- Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
- Traumatic Cataract: It can develop many years later after an injury caused to your eye.
- Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes.
- Radiation Cataract: It can form after you are exposed to some form of radiation.
A cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.
Why does it happen?
There are lens that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it.
However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.
Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few.
When should you opt for a cataract surgery?
Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightedness or alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night.
