The eyes are a very vital organ for a person to live a normal life. Vision makes social interaction, working, driving a car, cooking food or reading a book. All of these activities are made possible by our ability to see. But what if your vision becomes blurrier and cloudier over time? This experience may be caused by a cataract. A cataract is a clouding of the lens of the eye that is normally clear making it harder to see. Cataract happens when protein builds up in the eye making it cloudy, preventing light to enter the light, causing some loss of vision. New cells form outside of the lens, and the older cells are compacted into the center of the lens forming the cataract. Cataracts develop slowly and are unnoticeable at first, but will eventually interfere with vision. There are several types of cataracts, including: age-related cataracts (protein build up in the eye due to aging), congenital cataracts (pre-natal infection, injury or poor development can cause babies to be born with cataracts), secondary cataracts (cataracts that are a result of other medical conditions, exposure to toxic substances or radiation including ultraviolet lights and certain drugs) and traumatic cataracts (cataracts caused by injuries to the eye). Cigarette smoking, excessive drinking and air pollutions can also cause cataracts. Here is a list of 11 symptoms that can help determine if a person is at risk from cataracts.
1. Clouded, blurred or dim vision
This is the first and most obvious symptom of cataracts. Cataracts are caused by protein build ups in the eye. The body produces new cells outside of the lens clumping the older cells together forming a cataract. The cataract obstructs the entry of light into the eye causing a blurry or clouded vision. The images perceived by the eye are relatively dark and may become incomprehensible as the cataract thickens. At first, the blur is only within the area where the proteins are clumped the most. Because the cataract is still not affecting vision drastically, it is negligible. However, as the cloudy area grows, the images become less sharp and vision will become duller.
