Eyes are the windows by which we see and experience the world. Unfortunately, they are sensitive to certain lifestyle factors such as spending too much time in front of a screen, poor nutrition, and smoking. Also, as you age, they are prone to deteriorate, making it harder to work, read, play sports, drive, and engage in your favorite hobbies. Your eyesight is not something you want to lose.
The most common causes of poor eyesight include:
- Eye injuries
- Macular degeneration
- Diabetic retinopathy (caused by diabetes)
- Birth defects
Poor eyesight is characterized as:
- Loss of vision acuity (inability to see objects clearly)
- Unable to see as large an area as a healthy person
- Inability to look at a light
- Double vision
- Visual distortion
- Perceptual difficulties
- Any combination of the above
- The importance of vitamin A
Vitamin A is an antioxidant that belongs in the fat-soluble group of nutrients which include fat-soluble retinoids, including retinal, retinol, and retinyl esters. Vitamin A is important for vision as an essential component of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and functioning of the conjunctival membranes and cornea.
Eating foods that are rich in vitamin A will keep the health of your eyes in check. Don’t worry, you don’t have to eat bland, tasteless, foods to get more vitamin D into your system. In fact, there are quite a lot of foods rich in this essential nutrient that are delicious and can be consumed in a number of ways. Check them out!
Carrots have a reputation for a reason. Loaded with beta-carotene, an antioxidant which the body converts into vitamin A. Just one medium carrot alone contains about 200 percent of your daily value of vitamin A. According to one study, beta-carotene combined with vitamin C, vitamin E, zinc, and copper (which are all found in carrots) can slow the progression of macular degeneration.Open Next Page To See More
