The leaves are changing colour, the weather is getting chillier, and our daylight hours are becoming shorter. As autumn approaches, the signs are all around us, and you can be forgiven for packing away the shorts and t-shirt in favour of a windbreaker. In the midst of preparing for the season, make sure you keep those sunglasses out. A lesser-known sign of the changing season is where the sun sits in the sky, and this can have effects on your eye health.
As one of the leading causes of cataracts and blindness, UV rays from the sun are at their most intense during the fall. This may seem strange, given the dip in temperature, but this unique seasonal risk is caused by a combination of astronomy and human physiology. Unlike in the spring and summer, the sun is not directly above our heads during autumn. It is at a much lower angle. Typically, our brows protect our eyes from overhead sunlight. This time of year, though, the sun sits at an angle beneath our brows, and our eyes have to deal with much more direct sunlight.
While the sun’s damaging rays can definitely be problematic in the summer, they don’t shine directly into our eyes for most of the day. In the fall, they often are! The good news is that it is both easy and stylish to protect your eyes during this time of year.
Invest in a good pair of sunglasses with UV protection and polarized lenses. These are specially constructed with an optical filter between the two pieces of material that comprise the lens. Depending on the type of polarizer used, this will filter out light sources of a certain wavelength. The lenses found in polarized sunglasses specifically filter out UV light, blocking harmful sunrays from our eyes. And don’t think you won’t need them on cloudy days—as much as 90% of UV light can still find its way through cloud cover!
