To choose the right eyeglasses, the first task should be to know types of eyeglass lenses. Nowadays, eyeglass lenses can be classified into glass lenses, resin lenses, and PC lenses. Each of the three bear their own merits and drawbacks. The glass lenses are featured with stable refractive index and optical characteristics. What’s more, they are of great power to block UV. On the other side of the coin, glass lenses are heavy and breakable, which would bring harm to eyes. Resin lenses are of high visible light transmission and great power to block UV as well.

There are foods that you can add to your diet to strengthen and keep your eyes in great health. Your mom may have said to eat your carrots because they are good for your eyes. Anything high in Vitamin A and beta-carotene is great for your eyesight. But did you know that garlic is fabulous for keeping your eyes healthy. Garlic has sulfur which can help prevent cataracts. It also has quercetin which is also fabulous for good eye health. Other foods high in these are avocados, broccoli, onions, eggs, and asparagus.

You want to be sure that you are always well hydrated. Drinking water on a regular basis is a great way to stay hydrated. Drinking water helps to flush out the unwanted toxins in your body.

There are many things that you can do to protect your eyes and one of the most basic things it to protect them from the elements of nature. By just having sunglasses on during the day you will be protecting your eyes from the cold and dry wind as well as from the suns harmful rays.

The suns rays can contribute to the development of cataracts and macular degeneration. So be sure that you get sunglasses that have 100% UV protection and do not just wear them in the summer. You should be wearing them year round and especially in the car for the high water and snow glare. If you do not have a pair of sunglasses on hand then get a wide brimmed hat to shade your eyes.

Eat the right foods and get a good pair of sunglasses can block the ultraviolet and other harmful rays.

All people should wear sunglasses for protection from the damaging rays of the sun. Glasses that block out HEV, UVB and UVA light are the ones that are recommended. These will protect your eyes from at least possible skin cancer and cataracts.

When you leave your eyes unprotected for even a brief amount of time you risk getting them sunburned. This is often painful and gives you a feeling of having dirt in them. This will not cause permanent damage to your eyes. Not having any glasses that block out the suns’ rays over a long time period can be permanently damaging. People must be made aware of the damage that can occur to their eyes when left unprotected.

Researchers have found that long term exposure to UVA rays can be the cause of damage to your retina or cataracts. Extended exposure to UVB rays can lead to skin cancer around the delicate eye area. Short term exposure to UVB can inflame the cornea of your eye which can cause temporary blindness that can last up to 48 hours.

Eighty percent of exposure to the sun occurs when people are younger than age 18. Children are known to spend more time outside than adults. This is why it is very important to protect their eyes as well as your own. Glasses that block out at least ninety nine percent of harmful rays are recommended.

Try to find glasses that absorb up to 400nm. This is the same as a label that reads one hundred percent UV protection. Either plastic or glass lenses that have these labels will be fine for blocking out damaging rays.

The light that bounces off pavement or other smooth surfaces like water is called glare. Polarized lenses will cut down on glare but do little to protect your eyes. UV protection can be combined with polarized lenses so that you get both glare reduction and protection.

UV protection is not based on the color of the lens in your glasses. You can get a light amber lens and still have better protection than if you had a dark gray lens. The color of the lenses only matters for the protection from HEV rays. HEV stands for high-energy visible radiation. This will sometimes be called blue light.

Ultraviolet light is stronger than high-energy visible light, but the rays from the HEV light go deeper into the eye. This can cause retinal damage. Glasses that protect against this would be bronze, copper or reddish in color. The label on these might say blue blocking lenses. You can get all of the protection against UVA, UVB and HEV in one lens.
