Why You Should Take Care of the Health of Your Eyes

Most of us lead stressful, hectic lives, unaware of the fact that this has a huge negative effect on our bodies. Our eyes go through maximum exertion throughout the day, causing redness, puffiness and aching. This may ultimately damage the eyes. The good news is that you can counter most stress related eye ailments if you take regular care. Here are some useful tips to make things easier:

1.Yearly Check-Ups

A complete eye check-up once a year is an absolute must; you must never keep the check-up pending until you experience serious vision troubles. Delaying a visit not only increases existing problems, but may also create new ones. This is all the more necessary for those using cheap eye glasses or lenses, because wearing wrong 10 dollar eyeglasses will give you headaches, apart from vision problems. Therefore, if you can’t see well with your current glasses, have blurry vision or headaches, its time for a check-up, even if it’s not a year since the last time. An eye check up will help you keep many problems at bay.

2.Protect Your Eyes

Eyes and the area surrounding it are delicate and needs to be protected against the sun and dust. The best way to do this is to wear sunglasses whenever you’re outdoors. There are many people who think that Contact Lenses are enough protection for their eyes; which is incorrect as lenses merely protect your eyes, whereas sunglasses provide total protection from ultraviolet (UV) rays. You must choose sunglasses carefully by ensuring that their protection factor is not less than 98%. Another misconception is the fact that sunglasses are not required on cloudy days. In reality, they are as necessary on cloudy days as on sunny days. As clouds don’t block UV rays, the damage to your eyes is not less in any way.

3.Eat Right

There is no evidence to prove that your eyes are seriously affected by the diet and eating habits we follow, or that vision problems may be cured by eating or avoiding certain foods. However, a balanced and healthy diet can resist existing eye disorders, maintain eye health and also ward off some eye ailments. The food groups that are most beneficial for the eye are vitamins and minerals, especially Vitamins A, C and E. Minerals such as Zinc and Folic acid are good for your eyes. So make sure that you include lots of red fruits like carrots and citrus fruits like grapes or oranges to your diet.

4.Give your Eyes Proper Rest

Most importantly, you have to remember that eyes, like the rest of your body deserve proper rest. It’s advisable that you don’t compromise on your sleeping hours, or work on the computer for too long at a stretch, as these exert immense pressure on the eyes. Staring at the computer reduces blinking of the eyes, thereby causing them to dry up.

These are some of the simple ways, yet if you are careful to follow them regularly, you can keep your eyes in perfect shape. Take care!

Thanks to advances in laser technology and medical training, people who suffer from certain eye ailments can finally get relief from always wearing glasses. Previously, laser-assisted in situ keratomileusis or <a href=http://www.horizoneye.com/index.cfm/fuseaction/site.content/type/24693.cfm>LASIK</a> was available only to the very wealthy. Now through greater competition and lower prices it is now widely available to the masses. If you are ready to give up your glasses or <a href=http://www.horizoneye.com/index.cfm/fuseaction/site.content/type/24742.cfm>contact lenses</a> for the freedom of good eyesight, now is a great time to explore the benefits of LASIK eye surgery.

LASIK eye surgery is a common treatment for refractive errors of the eye, including:

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism

Treating and Myopia with LASIK

Approximately 30 percent of the population experience nearsightedness, which is traditionally treated with prescription glasses or contact lenses. In a normal eye, light passed through the cornea and the lens of the eye, converging on the retina, recording a sharp clear picture that your brain interprets. Myopia is a condition resulting from one of two conditions:

  • Elongated eye
  • Steep cornea

With these conditions, the light converges in front of the retina, causing blurry images for objects at a distance. Prescription glasses are used to correct the refraction and return the focus to the proper location on the retina. Using this same theory, LASIK corrects the focus in the same way be reshaping the cornea to do the same thing.

Treating Hyperopia with LASIK

Hyperopia is basically the opposite of myopia. Instead of the light refracting and focusing in front of the retina, the convergence occurs at a point behind the retina. Approximately 40% of adults have hyperopia to some degree. Conditions that lead to hyperopia are:

  • Shortened eye
  • Shallow cornea

Treating Astigmatism with LASIK

A typical cornea is rounded like a ball. With astigmatism, the cornea is shaped like a football or has a wrinkle that causes the light to refract erratically.

  • In a regular astigmatism, the foci are 180 degrees opposite along the vertical or horizontal axis.
  • Irregular astigmatism, which is typically caused by outside forces, disease, or injury, may have one or more foci in various locations that are asymmetrical.

How LASIK Treatment Works

LASIK uses the same theories for vision correction that are used in glasses and contacts. The difference is that the laser directly reshapes the cornea to correct the refraction.

During the procedure:

  • A flap is made at the front of the cornea and folded back
  • The laser, guided by a computer mapping is makes precise cuts in a predetermined pattern to reshape the cornea
  • The flap is replaced and also acts as a natural bandage over the corrected cornea

If you suffer from myopia, hyperopia with or without astigmatism and you want to get rid of eyeglasses or contact lenses, you should consider LASIK eye surgery. To find a Charlotte LASIK eye doctor please visit the website of Horizon Eye Care today.

Video Gaming may Improve Eye Contrast Sensitivity

Good news for men everywhere! Video gaming has proven scientific benefits to one’s contrast sensitivity in the visual cortex of the brain, a vital aspect of one’s vision, alertness to detail and eye health. According to scientists in Tel Aviv, video gaming may not only be good for your vision, it may even be a prescribed treatment for some eye ailments. This comes into stark contrast with earlier scientific estimates, which assumed prolonged video gaming would decrease vision. Gamers are more likely to notice minute differences in contrast, such as the differences between gray and black movement at high speed. Especially useful are video games like “Call of Duty” which are fast-paced games requiring concentrated focus and coordination of the eye. IN addition to increasing hand-eye coordination, video gaming is now scientifically proven to increase contrast sensitivity.

Scientists in Tel Aviv tested the contrast sensitivity of two groups over nine week. The first group played high-speed games for 50 hours over the test period while the other group did not play games at all. Gamers were not only more likely to notice details, but they could distinguish between more colors and shapes.

Gaming helps train the brain to notice these differences, something we hardly encounter in day to day life unless we do highly vision related jobs like truck driving or piloting. The gaming participants in the study improved 43% over the non-gamers, results which lasted for months after the initial gaming period. Scientists believe gaming trains the visual cortex in high-stress situations that help it to respond better in daily life. Funded by the National Eye Institute, the study shows that gaming has some positive benefits, and doctors will begin prescribing gaming to patients with lazy eye.
