Questions on Winter Eye Health and Wellness

Various types of eye issues and conditions can develop regardless of the season, but some eye problems may be more likely to occur during certain weather conditions. Depending on where you live, winter may mean increased winds, cold temperatures, and dry air. This winter weather can increase the risk of certain eye problems. 

To understand more, the article below answers winter eye health and wellness questions. 
​

Does winter weather cause dry eyes? 

The cold winter weather may dry out the surface of the eyes and lead to dry eyes. If you are prone to dry eyes, the cold air may worsen the problems. You can combat dry eyes this winter by: 

• Using artificial tears
• Drinking plenty of water
• Using a humidifier at home to keep air moist
• Not pointing car heaters directly at your face 
• Wearing sunglasses outside during the day

​

Does conjunctivitis occur more often in the winter?

Eye infections can occur at any time of the year, but according to the Cleveland Clinic, conjunctivitis is very common in the winter. Conjunctivitis, also called pink eye, involves inflammation of the white part of the eye. It can occur due to bacteria, allergies, or a virus. 

Viral conjunctivitis is spread by contact with those who have the infection. During the winter, people are often inside, and that close contact may facilitate the spread of infection. Remember, frequent handwashing is one of the best ways to decrease your risk of infection. Also, avoid rubbing your eyes as much as possible.
​

Can I wear contacts outside in cold weather? 

Although speaking to your eye doctor is always best, you can generally continue to wear contact lenses outside in cold weather. Even at low temperatures, contacts will not freeze to your eyes, but temperatures below zero may irritate the eyes and promote dry eyes. Contact lenses can increase the risk of dry eyes. Using artificial tears and taking a break from lenses may help. 

What is snow blindness? 

Snow blindness is a type of photokeratitis, which is a sunburned eye. The UV radiation from the sun reflects off the snow, and if you have excess exposure, it can cause snow blindness. You do not usually lose vision with snow blindness. Instead, symptoms include: 

• Blurry vision 
• A gritty feeling in the eye 
• Sensitivity to light 
• Redness

According to the American Academy of Ophthalmology, most cases of snow blindness go away on their own, but one of the best ways to prevent the condition is by wearing sunglasses that provide UV protection. 
​

Why do my eyes water a lot during the winter?

During the cold months, the air may dry out the surface of your eyes. This may cause your tear glands to produce more lubrication to combat the dryness. The result is increased tearing when you are out in cold air. Wearing sunglasses may lead to less exposure to cold wind. 

What causes winter eye allergy symptoms? 

If you have ever had eye allergies, you are familiar with the itching, redness, and burning. Winter eye allergies may occur due to increased time spent indoors during the colder months. According to the Asthma and Allergy Network, common indoor allergens include: 

• Pet dander
• Dust
• Mold

To decrease the risk of winter eye allergies, consider the following: 

• Dust and vacuum often 
• Use hypoallergic covers on pillows and mattresses
• Wash bedding and pillows regularly in hot water 
• Fix leaky faucets and check for mold buildup in areas that may get damp
