With review and feedback from CEENTA Ophthalmologist Pedro Cervantes, MD (SouthPark, Fort Mill, Steele Creek)Winter is around the corner, and as the weather gets colder, you may notice it gets more difficult to see. Are the cold temperatures to blame?What extreme cold does to your eyesExcessively cold temperatures can constrict your eye’s blood vessels or even freeze your cornea. This can cause blurred vision, double vision, or even a loss of sight. If you are in extremely cold temperatures and notice these symptoms, get into a warmer environment immediately. If your normal vision doesn’t return in a half hour, seek medical attention.Other ways cold can affect your eyesEven if you’re not exposed to extreme temperatures, normal cold weather can still have an impact. For example, cold air is usually drier than air at a more moderate temperature. This can dry your eyes out, causing discomfort, irritation, or even excessive tearing.How your heat can affect your eyesWhen it’s very cold outside, it’s natural to want to sit close to your heaters when you return indoors. However, that, too, can dry out your eyes.“I always tell patients that if they notice fluctuations in their vision, more often than not it is due to dry eyes,” CEENTA Ophthalmologist Pedro Cervantes, MD, said. “So, I encourage patients to increase the frequency of lubricating eye drops.”If there’s snow on the groundA further complication that could affect your vision is whether there’s snow on the ground. Snow reflects sunlight, which can make UV rays even intense than in summer months. In fact, they could even cause photokeratitis, or a sunburn on your eyes. While it usually goes away within 48 hours, it can still cause redness, pain, swelling, and light sensitivity. Therefore, sunglasses or other eye protection can be very beneficial.Eye care at CEENTAIf you need prescription sunglasses, you can purchase them at CEENTA.
