Many things change with age, including the eyes. From our cornea to our retina, the eyes undergo a variety of natural processes, but can also be prone to a variety of diseases. Here is more about what you need to know:

1. The Human Lens Changes with Age: Every human eye has a crystalline lens that allows for near vision. Over time, usually around age forty, the system that allows for the lens to give clear vision begins to change, which is when most people visit their optometrist for glasses to see near. However, sometime later, the lens will can also develop cataracts. In the early stages, cataracts are not a major problem as long as they don’t affect the part of the lens that controls central vision. As the cataracts progress, usually between the ages of fifty and eighty, the lens will need to be removed.
2. Fewer Tears: The quality of the tears that the eye makes changes with age. This can result in dryness or irritation, as well as the erosion of the front part of the eye.
3. Decreased Sensitivity: The eye becomes less sensitive with age, which can be dangerous because this may leave damage undetected. Seniors who already have ocular conditions, or who wear contact lenses should take extra caution in caring for their eyes. The loss of sensitivity can be aggravated by diseases like Shingles or Diabetes.
4. Age Related Macular Degeneration: Age is the single most important risk factor of Age Related Macular Degeneration, or ARMD, which will directly affect central vision. If caught early, ARMD can be treated with a variety of medications

Knowing what to expect will ensure that you can support your own eyes through the aging process. This will also help you understand more about the care that needs to be given to the seniors in your life.
