<p><strong>• What are Cataracts?</strong></p> <p>Cataracts are a very common eye condition that occurs as we age. Cataracts are formed when the lens in our eyes become cloudy. When this occurs, light cannot pass directly through your lens and vision is decreased. A cataract is neither a growth nor a film growing over the eye; it is simply the lens becoming foggy.</p> <p><img src="http://varion.co:3001/blogs/25/images/Cataract-visual-1024x1024.jpg" alt=""></p> <p><strong>• What are the causes of Cataracts?</strong></p> <p>There are several causes of cataracts, but the most common reason is aging. Other causes of cataracts include diabetes, trauma, eye conditions, medications such as steroids, eye surgery for other eye conditions, lifelong exposure to sunlight, tobacco smoking, poor diet lacking antioxidant vitamins.</p> <p><strong>• What are the symptoms of Cataracts?</strong></p> <p>Cataract development is usually slow. When a cataract starts to develop, you may feel that your vision is not quite right (as though you are wearing glasses and the lenses are dirty). Gradually, sight becomes cloudy making it difficult to see. You may feel as though you need a lot more light for reading. Another common symptom is a problem with bright lights. The lights cause glare or dazzle you more than they normally would. Some people can also experience a slight change in colour vision: things may appear a bit yellow. This mostly happens if one eye develops a cataract first and colours look different when compared to the other eye. If you experience any of these symptoms, you should contact your eye specialist. He will perform an eye examination and advise you as to whether or not you have a cataract and how badly it affects your vision.</p> <p><img src="http://varion.co:3001/blogs/25/images/cataracts+demo-2.jpg" alt=""></p> <p><strong>• What treatment options are available?</strong></p> <p>The only effective treatment for cataracts is surgery. During this procedure your Ophthalmologist will remove the cloudy lens and replace it with an artificial lens implant which eventually becomes a permanent part of your eye. There is no evidence suggesting that vitamins, diet changes or use of eye drops can cure cataracts.</p>
