Cataracts: Symptoms Types Causes and Treatment

Cataracts

A cataract is a cloudy area that creates on the lens of eyes.A cataract begins when the eye's proteins create clumps that prevent the lens from sending clear images to the retina. The retina works by changing the light that passes through the lens into signals. It transmits signals to the optic nerve, which transports them to the brain. It develops slowly and eventually affects your vision. You may have cataracts in both eyes, but they are usually not at the same time. Cataract is common in the elder people.

Symptoms of Cataracts

• Cloudy vision, obscure or dim
•  Increased difficulty with night vision
•  Sensitivity to light and glare
•  Reading and other activities require a brighter light
•  Looking halos around lights
•  Frequent changes of eyeglass prescription or contact lens
• Yellowing of colors
•  Double vision in single eyes

Causes of Cataracts

You develop them when the protein accumulates in the eye lens and makes it cloudy. This prevents the light going clearly. You may lose some of your sight. There are different types of cataracts. These include:

Age-Related. They create as you grow older.

Congenital. This is what doctors give him when babies are born with cataracts. They can be the result of infection, injury or poor development of the uterus. Or, they can be in their youth.

Medical Conditions. These are due to medical conditions, such as diabetes. They may result from toxic substances, ultraviolet light or radiation or from taking medicines such as corticosteroids or diuretics.

Traumatic. They are formed after an eye injury

Types of Cataract

Nuclear Cataract

Cataract affecting the center of the lens. At the beginning, nuclear cataracts can create more expectations or even temporarily improve vision. But over time, the lens gradually becomes a closer yellow and the scene is still darkens. As the cataract progresses slowly, the brown target can even be made. Differentiating the color lens may cause difficulties in differentiating color prizes.

Cortical Cataract

A cataract that affects the edges of the lens. Cortical cataract begins as opacity or whitish dinge-ding strips on the outer edge of the lens cortex. As it progresses slowly, the strips stretch towards the center and interfere with the light passing through the center of the lens.

Subcapsular Cataract

Cataract hitting the back of the lens. Existing subcapsular cataracts begin as a small opaque area, usually behind the lens, just beside the path of light. Subcutaneous cataracts often revert to vision reading, reduce vision in bright light and cause glare or slab around the lights during the night. These types of cataracts usually emerge more quickly than other types.

Congenital Cataract

Cataract in which you were born. Some people are born with cats or develop them during childhood. These cataracts can be genetic or involve infection or intrauterine trauma. These cataracts may be due to certain conditions, such as myotonic dystrophy, galactosemia, neurofibromatosis of type 2 or rubella. A uterine cataract does not always affect eyesight, but if it does, they are usually removed immediately after detection.

How to Prevent Cataract

Fruits and vegetables have many antioxidants, which help maintain eye health. Some research shows that eating antioxidant-rich foods such as vitamins C and E can help to prevent catkins. If you already have cataracts, this can slow down their growth. Good sources of vitamin C include:

• Citrus fruits (orange, grapefruit, lime, etc.)
•  Tomatoes and tomato juice

•  Kiwi
•  Broccoli

•  Brussels
•  Yellow watermelon
•  Potatoes

Treatments of Cataracts

Home Treatment. Earlier, you may be able to make modifications to manage your catalyst. You can do things as follows:

• Use brighter lights at home or at work
• Wear anti-glare sunglasses
• Use magnifying lenses for reading and other activities

Glasses or New Contacts. A new prescription for glasses or contacts lenses may help you see better with earlier catheters.

Surgery. Your doctor may recommend surgery if your catheter starts opening in everyday activities such as reading, driving, or watching TV. During cataract surgery, the doctor removes the blurred lens from office and replaces him with a new artificial lens (also called intraocular lens or IOL). This surgery is very safe, and 9 out of 10 people can get it better later.
