A cataract is a clouding of the natural lens that sits in the eye right behind the iris, the colored part of the eye. Typically, cataracts are a result of the normal aging process of the lens. From childhood until the time of cataract surgery, this lens is changing. Cataracts are the most common cause of vision loss over the age of 40.
Signs and Symptoms of Cataracts
Early on, you may not even know that you have the beginning of a cataract. Often, the first symptoms of a cataract are an increase in nearsightedness called “second sight”. These patients notice that their near vision is actually improving from where it had typically been. This improvement in near vision is short-lived. As the cataract continues to grow, it will cause an overall blurring of one’s vision. Patients will also develop glare and halos around streetlights and headlights at night. This is a result of the scattering of light by the cataract. One’s perception of colors will also change as a cataract progresses. Colors will be less bright and may have a brownish hue.
