Winter weather can cause your eyes to feel dry and uncomfortable. To combat these unwanted side effects of chilly weather, try the following tips: Always wear sunglasses outdoors. They'll protect your eyes from harmful UV rays and shield your tear film from harsh or cool winds. Sip on hydrating fluids throughout the day to help keep your tear film stable. Use a cool-mist humidifier in your home or work space to put moisture back into the air. Always direct space heaters or car heaters away from your eyes. They can cause your tears to evaporate prematurely. Visit your local optometrist at the first signs of discomfort. We're here to help!
