Many people associate sun protection with summer, but winter sun can be equally harmful to your eyes. Snow reflects up to 80% of UV rays, creating a double dose of exposure that can lead to photokeratitis, commonly known as snow blindness. This painful condition causes temporary vision loss and feels like having sand in your eyes. Even on cloudy winter days, harmful UV rays penetrate through clouds and reflect off snow-covered surfaces.
Quality sunglasses are your first line of defense. Look for pairs that block 99% to 100% of both UVA and UVB radiation. Wraparound styles offer additional protection by preventing rays from entering around the frames. Polarized lenses can reduce glare from snow and ice, making winter activities safer and more comfortable.
Winter air lacks moisture, and indoor heating systems make the problem worse by further reducing humidity levels. This combination creates the perfect storm for dry, irritated eyes. You might experience burning, redness, or a gritty sensation. Some people even find their eyes watering excessively as the body tries to compensate for dryness.
Combat dry eyes by using a humidifier in your home and office. Artificial tears can provide relief throughout the day. Remember to take regular breaks from screens, as we blink less frequently when focused on digital devices. The 20-20-20 rule helps: every 20 minutes, look at something 20 feet away for 20 seconds.
Winter is an excellent time to schedule your comprehensive eye examination. Your optometrist can assess any seasonal eye concerns, update your prescription, and recommend specific protective eyewear based on your lifestyle and activities.
Don't let winter weather compromise your vision. With the right protective measures and quality eyewear, you can enjoy all the season's activities while keeping your eyes healthy and comfortable. Your vision is precious, so make eye protection an essential part of your winter routine.
