The human eye is a fascinating part of the body. It allows us to observe the world around us in a spectacular way. The eye picks up data from what we observe and instantly sends a message to the brain allowing us to perceive light and dark, many beautiful colors and shapes and the overall wonders of this world (natural and man-made). The gift of sight is not something to be taken for granted though.
Some people are born blind, and have to go through life relying on their other senses to make decisions. Accidents happen all the time as well and can affect our vision negatively. And just the normal human process of aging can affect our vision and cause it to slowly deteriorate. But thankfully we live in a day and age where a lot of the problems we can encounter pertaining to our eyesight can be remedied. From simply getting a pair of glasses or contact lenses, to complex cornea transplants and cataract surgery, there are a number of solutions to modern day issues with our eyes.
It’s important to take care of our eyes while we can so we don’t develop serious problems later in life. For example, prolonged exposure to ultraviolet light and radiation can have a negative effect on your vision. You may have heard your mother yelling at you when you were younger not to look directly at the sun while you were outside playing. Well, it turns out there is some wisdom behind that other than the fact that staring directly at the sun is painful.
There have also been some interesting studies done that show that other types of radiation can cause cataracts. Pilots and astronauts who spend a lot of time closer to space and in thinner atmospheric conditions tend to get cataracts more frequently than others. Also, a lack of iodine intake can lead to cataracts as well (thank goodness for iodized salt!). However, sometimes cataracts occur happen to people because of old age or even a genetic disposition. In a lot of cases though there is a solution: cataract surgery.
It’s important to remember that good eyesight can also be affected by the type of diet you consume. Because your eyes are just as important as other parts of your body like muscles and bones, it’s also important that they receive the right nutrients and vitamins in order to function like they should. Studies from the National Eye Institute have shown that food rich with beta carotene, vitamin C, vitamin E, zinc, omega-3 fats, lutein, and zeaxanthin are all beneficial for your eyesight and can’t prevent or prolong the effects of again and eyesight. Try to incorporate food like carrots, sweet potatoes, turkey, spinach, and wild salmon into your diet to keep your vision the best it can be.
If you have questions about your eyesight or cataracts, a good source of knowledge is a vision center. Usually vision centers handle everything from cataracts to LASIK eye surgery and can answer pretty much all of the questions you may have. And the surgeries and solutions that are available at these centers continue to improve each and every year.
