Introduction to Cataract – All about Vision

The cataract is a commonly occurring condition, which affects the quality of vision and also is known for acting as a leading cause of blindness in many countries of the world. Your eye is a great creation of nature which has to perform the most important functions. There is a huge similarity present between working capacity of camera and human eye. Light rays coming from a point of focus pass through different structures before striking the retina, which transmits signals to brain for the interpretation of objects that you are seeing. Lens plays an important part in refracting light rays on your retina as it is a clear medium, which ensures that light entering human eye gets the treatment, which it deserves.

The cataract is a condition where lens becomes opaque and loses its clarity this will lead to a situation where light will not pass through lens and retina will not send signals to brain as a result you will not get the potential of seeing things. This is the reason that cataract is also known as cloudy lens. Some of the symptoms associated with this condition are being mentioned below so that readers can have a clear idea.
