People associate bright light with warm weather, sunglasses are not necessarily for warm weather they are for bright light and winter is the time where we actually get the brightest light particularly in the times of the day where people will be commuting i.e. early morning or late afternoon when the sun is low. Here are 5 great reasons you should wear sunglasses in winter.
Sunglasses Protect from Harmful UV Rays
The exposure to ultraviolet rays is often associated with the development of age-related macular degeneration and cataracts. Most quality sunglasses can block 100% of harmful UVA, UVB, as well as UVC Rays. They can also help to provide excellent protection to the delicate skin around the eyes. This helps to prevent premature aging and wrinkles caused by UV rays. The sun glaring off the snow can compound the issue. So it is important to wear sunglasses for long-term eye health.
Sunglasses Improve Vision
For long term health and good vision, the eyes require just the right amount of light. Too little light is just as bad as too much light. Beyond that excessive glare can reduce visual acuity and cause light-induced bleaching of the retina. So it is important to buy high-quality sunglasses for improved vision and healthy eyes.
Sunglasses Reduce Glare
Winter precipitation tends to coat every surface in snow, ice, and water. This results in extremely bright reflections that can severely impair vision and cause glare. This reflective can be dangerous while skiing, snowmobiling, and driving. Wearing high quality sunglasses can help to reduce the glare dramatically, thus, providing a more comfortable and safer vision. Polarized lenses are very effective at shielding the eyes from dangerous reflections.
Sunglasses Protect the Eyes from Dust, Wind, and Debris
Sunglasses can help to reduce the evaporation of natural moisture and create an effective wind barrier to keep the eyes comfortable. Wearing sunglasses can also keep contact lenses from drying. They can also help to prevent windblown particles from causing corneal abrasions. Close fitting and wraparound style sunglasses are especially effective at preventing injuries from dust, wind, and debris. There are even some lenses with special hydrophobic coatings. This coating helps to repel dust, oils, lotions, water, and fingerprints to help in keeping the eyes safe and vision streak free.
Sunglasses Reduce Eyestrain and Headaches
The pupils help to control how much light reaches the light sensitive retina in the back of the eye. The pupils dilate to allow as much light in as possible in dim light. The pupils constrict to prevent too much light from striking the retina when the light is bright. The pupil cannot constrict enough to reduce light exposure to a comfortable level in extremely bright conditions. In an attempt to reduce the amount of light entering the eyes squinting may occur. The constant construction of the pupils and squinting can lead to eyestrain and headaches. Sunglasses can help to reduce the amount of light reaching the eyes. This in turn help to increase comfort while also reducing the painful side effects of fatigue. In this case, photochromic lenses (lenses that darken automatically in the presence of bright light) provide the beat approach to protect the eyes against bright lights and for reducing eyestrain.
