Think of your eye as a camera lens, you go to take a picture but you can’t quite snap a clear image because of something fogging up the lens. This is similar to the vision of a person with cataracts. Cataracts cloud the visual field so that light cannot pass through the lens as precisely, resulting in poor vision.

Simply put, the way we are able to see is the result of hard working parts of the eye. The lens is the portion of the eye behind the pupil that channels light to the retina. The retina is where are images are formed. The lens of our eye is made up of water and proteins, and as we age those proteins can break apart or clump together to form cloudy vision. When the proteins clump together it fractures the light trying to reach the retina, so it makes it more difficult to develop a clear image.

Generally, if a person never needed to have a pair of glasses and had 20/20 vision, even after hitting your older years, this would be a rare occurrence. Almost everyone eventually finds their eyes struggle to focus and they end up needing a pair of reading glasses or bifocals. Unfortunately, the deterioration of eyesight is a common issue that typically begins for patients around the age of 40 and continues to worsen until about the age of 65. Just like the rest of the human body, eyes do not stay physically strong forever. This makes the ability to focus on something in the distance and then transition focus to something up close up very challenging.

Glaucoma is a progressive eye disease that is caused by a damaged optic nerve. Typically, trauma to the optic nerve is the result of a buildup of fluid at the front of the eye creating pressure on the optic nerve.

The optic nerve is a bundle of smaller nerves that send signals to the brain from a stimulus to the eye. As glaucoma progresses and the damage to optic nerve increases, sporadic blind spots will begin to arise in the field of vision. When the progressive disease takes over the entire nerve, blindness can be the end result. There is no cure for glaucoma yet but there are treatments and medication prescribed by ophthalmologists that dull the side effects and symptoms. Symptoms can vary but may include:

It is never too early to start caring about your eye health. By paying attention to your surroundings and implementing some easy, but important tricks, you can help prevent vision degeneration and other eye related issues that arise from improper eye care.
