Many people associate sun protection with summer, but protecting your eyes from winter sun is just as important. Even on cold or cloudy days, UV rays can affect your eyes, and snow can reflect sunlight in ways that increase glare and discomfort.



This blog is for patients and families in Howell, Brighton, Hartland, Pinckney, and surrounding Livingston County communities who want clear, reliable guidance. Below, you’ll learn why winter sun still poses a risk, when sunglasses matter most, and what lens features can help keep your eyes comfortable and protected throughout the season.

Is Sun and UV Exposure Really a Risk in Winter?

Yes. UV exposure is a year-round concern, even when temperatures are low or skies are overcast.  UV exposure is actually often more damaging in the winter due to less humidity disbursement. 

The sun’s ultraviolet rays do not disappear in winter. While the sunlight may feel less intense, harmful UV radiation is still present and can affect eye health over time.

Winter conditions can actually increase exposure in certain situations:

• Snow reflects sunlight, sometimes increasing glare and UV exposure
  
  
• Cloudy days still allow UV rays through, even when the sun is not visible
  
  
• Lower sun angles can make glare more noticeable, especially while driving
  
  

Patients in Michigan often experience this during winter driving, outdoor walks, or time spent in snowy environments. Protecting your eyes from winter sun helps reduce both short-term discomfort and long-term risk.

Should You Wear Sunglasses During Winter?

Yes. Sunglasses are not just a warm-weather accessory. They play an important role in winter eye comfort and protection.

Wearing sunglasses in winter can help:

• Reduce glare from snow and ice.  There are 4 types of glare, including BLINDING glare.
  
  
• Protect eyes from UV exposure
  
  
• Improve visibility while driving
  
  
• Shield eyes from wind and cold air
  
  

Many patients notice that winter glare feels more intense than summer glare, particularly on bright, snowy days. Sunglasses can make outdoor activities more comfortable and help reduce eye strain.

For patients in Howell, Brighton, and Hartland, sunglasses are especially helpful during daily commutes, outdoor exercise, and winter recreation.

What Types of Lenses Help With Winter Sun and Glare?

Choosing the right lenses can make a meaningful difference in both comfort and clarity during winter months.

UV Protection

Lenses with UV protection are recommended year-round. They help block harmful rays that can affect long-term eye health, regardless of season.  Most lenses come automatic with UV protection.  All prescribed optical lenses have some form of UV protection. 

Polarized Lenses

Polarized lenses are particularly helpful in winter. They reduce glare caused by sunlight reflecting off snow, ice, and wet roads. This can improve visual clarity and reduce eye strain, especially while driving.

Prescription Sunglasses

For patients who wear glasses, prescription sunglasses provide clear vision and protection at the same time. They eliminate the need to choose between seeing well and protecting your eyes outdoors.

Built-In UV Protection for Everyday Lenses

Some everyday lenses include built-in UV protection, which can be helpful for short outdoor exposure. However, they may not reduce glare the way dedicated sunglasses do.

An eye exam is a good opportunity to discuss which lens options fit your daily routine and winter activities best.

When Is Winter Glare Most Likely to Cause Eye Discomfort?

Winter glare tends to be most noticeable in specific situations.

Common examples include:

• Driving early in the morning or late afternoon
  
  
• Walking outdoors on bright, snowy days
  
  
• Spending time near ice or open snow-covered areas
  
  
• Outdoor winter sports or activities
  
  

Glare can lead to squinting, eye fatigue, headaches, or temporary visual discomfort. Wearing appropriate eye protection helps reduce these effects and makes daily activities more comfortable.

At Designs For Eyes, patients often ask about winter-specific lens options that support both safety and visual clarity during these conditions.

Why Year-Round Eye Protection Matters

Protecting your eyes from winter sun is not just about comfort. Long-term UV exposure can contribute to eye health issues over time.

Consistent eye protection helps:

• Reduce cumulative UV exposure
  
  
• Support long-term eye health
  
  
• Improve daily visual comfort
  
  
• Minimize glare-related strain
  
  

Making sunglasses part of your winter routine is a simple step that supports eye wellness throughout the year.
