Our Eyes, Windows to Our Soul
How important are your eyes? Well, shut them and tell me what you see. Let me guess, absolutely nothing, that is how important your eyes are. Your eyes are receivers of light; it is your eyes that tell you how things are perceived. Without your eyes, the world would not seem so intriguing, as all the beautiful colors and places would just be a vast void to us. Without eyes, many things wouldn't even have any importance such as fashion or beauty. In pitch black, everything is either beautiful or everything is ugly—how you perceive it is up to you.
Eyes are Work Horses
This world that we live in is technology-driven, and as such, many things are done by the use of a computer with an output device such as a computer screen. Millions, if not billions of people spend millions of hours working their eyes by reading. Scholars spend thousands of hours on the internet. Writers and readers of electronic content spend thousands of hours working their eyes online. Teenagers and social media junkies spend millions of hours sending messages via tablet, laptop, desktop, or phone, constantly working the eyes. As it stands in today's world, 50% of people have more than one computer technological device that is used to type or read messages. Most people have a cellphone and a laptop or desktop at home. Most students have laptops, tablets, and smartphones. That is a lot of work for those flashlights in your head.
We Destroy Our Own Eyes
Our eyes, like any other part of our body, need rest. Have you ever heard the term "tired eyes?" Yes, your eyes do get tired and do need to rest. There are various ways we harm our eyes without we even knowing it;
- Radiation from the sun not only is harmful to your skin but gradually damages your eyes.
- Viewing or reading under poor light.
- Working in environments that emit dust, smoke, and other chemicals without protective eyewear.
Basic Understanding of the Eye
The iris is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. The color of the iris gives the eye its color.
The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. While the cornea contributes most of the eye's focusing power, its focus is fixed. The curvature of the lens, on the other hand, can be adjusted to "tune" the focus depending upon the object's distance.
The crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina. The lens, by changing shape, functions to change the focal distance of the eye so that it can focus on objects at various distances, thus allowing a sharp, real image of the object of interest to be formed on the retina. This adjustment of the lens is known as accommodation. Accommodation is similar to the focusing of a photographic camera via movement of its lenses. The lens is more flat on its anterior side than on its posterior side.
Is a light-sensitive layer of tissue, lining the inner surface of the eye. The optics of the eye create an image of the visual world on the retina (through the cornea and lens), which serves much the same function as the film in a camera. Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centers of the brain through the fibers of the optic nerve.
The optic nerve, also known as cranial nerve II, transmits visual information from the retina to the brain. Derived from the embryonic retinal ganglion cell, a diverticulum located in the diencephalon, the optic nerve does not regenerate after transection.
Feed Your Eyes
While you probably can't change your vision with diet alone, you can make sure your eyes have all the nutrients they need. Try to incorporate these foods into your meals:
- Carrots: Carrots are rich in beta-carotene, a carotenoid pigment found in many orange fruits and vegetables. Beta-carotene is an important precursor for vitamin A. An extreme lack of vitamin A can cause blindness.
- Salmon or tuna: Several studies suggest omega-3 fatty acids may help protect adult eyes from macular degeneration and dry eye syndrome. Essential fatty acids also may help proper drainage of intraocular fluid from the eye, decreasing the risk of high eye pressure and glaucoma.
- Citrus (orange, lemon, lime and grapefruit): Vitamin C and bioflavonoids are important antioxidants that help keep your eyes and body healthy. Foods high in vitamin C, such as citrus fruits and many vegetables, are also excellent sources of bioflavonoids.
Quit Smoking—See Better
I can't begin to tell you all the negative effects of smoking, putting anything other than oxygen in your lungs is a sure recipe for illness. Cigarettes contain deadly chemicals such as tar, polycyclic aromatic hydrocarbons, formaldehyde, carbon monoxide, and heavy metals. Research has shown that cigarette smoking is a leading factor in two factors of vision loss, cataracts, and macular degeneration.
Reduce Eye Strain
Like any other muscle, the muscles around your eyes can start to feel fatigued and painful if you strain them too much. Try these tricks to cut back on visual fatigue:
- Rest your eyes when you feel the need to. The body is built to take care of itself and sends out various signals when it is ill or needs rest. Rest is important as it helps to re-energize and rejuvenate the eyes.
- Practice the "20-20-20" trick. If your work involves staring at a screen for long periods of time, take a break every 20 minutes, and focus on a point 20 feet away for at least 20 seconds.
- Turn down brightness. If you're looking at a computer or television screen, turn down the brightness to the lowest possible level or a level that is comfortable to your eyes. You should still be able to see, but you shouldn't feel like you're staring at a bright light.
- Make text bigger. If you're reading on a computer, and you are straining to see smaller text, use your program's zoom function to make the text larger. Or, if reading the small print in books is a problem, invest in a reading magnifying glass or buy larger-print editions.
Try Eye Exercise—Palming
When your eyes start feeling strained and tensed after doing a lot of close work, try this quick treatment.
- Rub the palms of your hands energetically and fast.
- Place the palms over your eyes when they are tingling and warm and sit quietly for a few minutes.
- Don’t press your eyes. Hold them gently with your palm. Your eyes will be soothed, relaxed, and refreshed from the warmth and energy transmitted from your hands. This is your own healing energy.
- Surrender each out breath with a long gentle sigh while breathing softly.
- Allow your eyes to be completely passive and let them experience whatever they are treated with.
- Behind your hands, open your eyes and see softly in the darkness.
- Finally, you can slide your fingertips softly, starting from your forehead, your eyelids, nose, cheeks, lips, and your chin.
Always remember that having healthy eyes is as important as having a healthy heart. The eyes are two of the most special bodily organs in the body that allows us to enjoy and appreciate the beauties and differences that the world has to offer.
