An eye contains a natural lens that bends light rays that come into contact with an eye to help aid in vision. The lens should remain clear at all times to ensure the individual will be able to see without error. If the lens becomes cloudy, the individual is considered to have cataracts.
Cataract is the most common cause of vision loss in individuals over the age of 40 years and is the principal cause of blindness throughout the world. Listed below are the three different types of cataracts that can develop.
Types of Cataracts
- Subcapsular Cataract – This occurs at the back of the lens. Those who suffer from diabetes or those who take high doses of steroid medications are at a greater risk of developing this type.
- Nuclear Cataract – Nuclear cataract forms in the nucleus (central zone) of the lens. This type is typically associated with aging individuals.
- Cortical Cataract – Occurs in the lens cortex which is the part of the lens that surrounds the nucleus. It is identified as white, opacities that start in the side of the lens and work their way to the center in a spoke-like manner.
