A Healthy Diet, And Healthy Eyes
Over a 12-month period in 2022, we saw many occurrences through our eyes. In 2022 there were signs of a slow economy, inflation, health care, and climate issues, and we began moving forward with COVID-19 behind us. December 2022 is “Prevent Blindness” awareness month and every individual should cherish the joyfulness of healthy vision and its amazements, and be active in supporting eye-sight-saving services. During this time period, there is a focus on creating awareness about eye vision and health by increasing community knowledge through education, advocacy, early detection, and research. Approximately 50% of all blindness is avoidable. However, each individual must take an active role in preserving their vision health.
You can prevent vision loss with early diagnosis and proper treatment. With earlier diagnosis and treatment of cataracts, macular degeneration, and glaucoma you can protect your vision health and improve the overall outlook for your eyes.
Our Eyes Make It Possible To See The Beauty Of Everything Around Us
Each morning, we open our eyes and there is a treasure in the wealth of visual information. The eyes and the brain structures are complex systems that allow us to experience visual information from the surrounding world. It is easy to take clear vision for granted, but even subtle changes in the structure or functioning of the eyes can disrupt our sight. An eye care provider conducts a thorough eye exam to ensure that these components are functioning well together.
Our eyes sit in a bony protective socket, the orbit, which has six extraocular muscles in each eye. These muscles allow movement of the eye up and down, side to side, and eye rotation. The eyeball is not a single, spherical structure as is commonly thought. It consists of a smaller, curved portion called the cornea that attaches to a larger, roughly spherical structure called the sclera (the white of the eye). The eyeball contains a jelly-like substance called vitreous fluid.
Toward the front of the eye are three essential structures: the iris, pupil, and lens. The iris is the colored part of your eye – it can expand and contract to determine how much light to let in through the pupil, the black hole in the center of your eye. Finally, the lens is a flexible, convex structure that changes shape to direct light rays in different directions within the eye.
At the back of the eyeball is a layer of tissue called the retina. The retina consists of millions of photosensitive cells that react to certain types of light. Cone cells are clustered toward the center of the retina and react to colors and details in bright light. Rod cells, which are spread toward the periphery of the retina, react to dim lighting conditions.
