Five Key Reasons Why You Need To Wear Sunglasses

Sunglasses are now synonymous with high fashion

. They can change you look and attitude with most westerners owning at least two pairs. Fashion aside, wearing sunglasses are key to your eyes health which is why you need to choose good quality, 100% UV protected sunglasses.

1. There is Science behind the Dangers of Ultra Violet Light

The diameter of a pupil is around 3 mm on a normal bright sunny day. Dark lenses in sunglasses will increase the pupil dilation to 4.5mm diameter. Therefore about 2.5 times more light is reflected into the eye, traveling through your pupil to reach your retina. Add in the intense sunlight and UV of the Australian sun and these figures could be even greater.

However only around a tenth as much light is able to reach your eye if youre wearing good quality sunglasses. The amount light reaching the retina is reduced by a factor of around 4.

2. Retina Damage from UV Light

However if youre wearing cheap sunglasses, the harmful UV rays will not be filtered out, causing damage to your retina. With this research its clear that eye safety should be a key factor when buying a pair of sunglasses.

3. Eyestrain and Headaches

Long exposure to UV rays can cause or worsen migraines, tension, and headaches. Headaches can be reduced, and at times prevented, when wearing sunglasses, especially if they have polarized lenses that also reduce the glare as well as UV light.

4. Dry Eye Syndrome

Dry eyes can be very uncomfortable causing squinting and general blurriness. Wearing sunglasses can reduce the amount of heat and direct sunlight absorbed by the eyes and assist in keeping eyes moist by reducing the evaporation of tears. The eyes need moisture to focus and perform correctly.

5. Driver Safety

Bright sunlight and glare are a drivers worst nightmare without proper sunglass protection, and it can be downright dangerous. UV rays that are refracted off a road can be more intense than just being outside and requires good quality lenses, preferably polarized, to help prevent distracting and dangerous road glare.Research has proven that purchasing the best quality sunglasses available gives the eyes the best possible protection from the sun. Polarized sunglasses are the best choice for sporting activities and the optimal choice for driving. Having scratch free lenses also increases the visibility and comfort when wearing sunglasses. When your brand name sunglasses get scratched lenses its wise to consider scratched sunglass repair rather than tossing the sunglasses away. Its the quality of the sunglass lenses that is key to giving your eyes the best protection from UV light and glare.
