Cataracts are deposits of protein that accumulate on the eye's lens, obscuring vision. When cataracts first begin affecting your eyes, the problem may escape notice. However, cataracts gradually worsen over time and eventually need to be corrected. Here are five symptoms you may develop when the lens of your eye begins to lose its transparency: 1. Seeing Double Cataracts may cause you to experience double vision (diplopia). This effect sometimes shows up early in the development of a cataract. You could find yourself shaking your head and squinting to try to get rid of double images. This problem may be accompanied by eye pain as you strain to see clearly. Diabetes, stroke, shingles and many other medical conditions besides cataracts can cause diplopia, so it's a good idea to see both your primary care doctor and an eye doctor if this symptom persists. 2. Foggy Outlook Fuzzy or blurred vision is a classic symptom of cataract formation. You will probably notice this problem if a cataract forms near the center of your lens. Objects may appear foggy or unclear. The haziness can affect just one eye or both eyes. Cataracts don't actually spread from one eye to the other, but they may develop on each lens independently. Once they begin to form, they don't go away. However, it may take years for them to reach the point where cataract surgery is required. 3. Light Sensitivity If bright lights cause you to blink or squint in pain, cataracts may be the culprit. Light sensitivity can impact your ability to perform normal activities. Sunglasses will help you cope with bright light during the day, but nighttime is a different matter. You may decide not to drive at night anymore because the glare of oncoming headlights bothers you too much. 4. Rapid Changes Myopia (nearsightedness) tends to worsen as cataracts grow. If your prescription is getting stronger every year, your optometrist or ophthalmologist may perform additional tests to discover if cataracts are the cause. Stronger glasses or contacts can only adjust for the loss of visual acuity up to a point. LASIK surgery on the cornea also won't completely correct vision for people who have already developed cataracts. LASIK doesn't fix the underlying problem with the lens. 5. Lens Appearance


As the lens becomes opaque, the pupil may appear to change color from black to white/yellow. Unless the condition has progressed very far, a cataract is not visible to the naked eye. By the time the cloudiness is noticeable to other people, your vision will be seriously impacted. Surgery to remove the affected lens and replace it with an artificial intraocular lens such as Crystalens may be recommended. Even with cataracts that are very advanced, sight can usually be restored.

When it comes to vision correction, procedures such as cataracts surgery and LASIK are some of the most effective and permanent solutions. However, before deciding to receive these treatments, it is important to consult with a leading eye surgeon in your area (such as a New York LASIK specialist) to receive in-depth analysis as to whether you are a good candidate for such procedures.
