With the arrival of winter, many people wonder if it is really necessary to wear sunglasses. After all, the sun seems less intense during the colder months of the year. However, it is important to know that UV rays can be just as dangerous in winter as in summer. That is why it is recommended to continue wearing sunglasses, even during the cold season.
Why are sunglasses important in winter?
Although the sun is less intense in winter, its UV rays can still be harmful to our eyes. In fact, the reflection of light off snow can even amplify the effects of UV rays. This can lead to a range of eye problems, including:
1. Corneal damage
UV rays can damage the cornea, the clear part at the front of the eye. This can lead to a painful inflammation known as keratitis. Symptoms can include red eyes, a burning sensation, and sensitivity to light.
2. Cataracts
Prolonged exposure to UV rays increases the risk of developing cataracts, an eye disorder where the lens of the eye becomes cloudy. This can lead to blurred vision and loss of clarity.
3. Age-related macular degeneration
UV rays can also contribute to the development of age-related macular degeneration (AMD), a disease that affects the central part of the retina. This can lead to loss of central vision, making tasks like reading or driving difficult.
4. Pterygium
A pterygium is a fleshy growth that forms on the surface of the eye. Although benign, it can become bothersome and require surgical treatment. Exposure to UV rays is one of the main risk factors for developing a pterygium.
How to choose the right sunglasses for winter?
When choosing sunglasses for winter, it's important to make sure they offer adequate protection against UV rays. Here are some tips to help you make the right choice:
1. Look for UV 400 protection
Make sure your sunglasses block 100% of UVA and UVB rays, which means they have UV 400 protection. This is the highest and most recommended level of protection.
2. Choose large glasses
Larger lenses that cover more of your face will provide better protection from UV rays that can penetrate from the sides.
3. Opt for wraparound frames
Wraparound frames that fit the shape of your face will also better block side UV rays.
4. Prefer polarized lenses
Polarized lenses reduce glare and improve clarity of vision, which can be especially helpful in winter when light reflects off snow.
5. Think about the color of the glasses
While color choice is often a matter of personal preference, certain tints can offer specific benefits. For example, gray or green lenses are ideal for outdoor use because they reduce eye strain without overly darkening vision.
When to wear sunglasses in winter?
You should consider wearing sunglasses in the following situations during winter:
- When you are doing outdoor activities like skiing, snowboarding or hiking, the reflection of light on the snow can be extremely intense.
- When driving. Sun glare can be dangerous, especially on snowy roads.
- When you are exposed to sunlight for long periods of time, such as when walking or shopping.
- When you are in very bright environments, such as ski resorts or cross-country ski trails.
Conclusion
In conclusion, it is highly recommended to continue wearing sunglasses in winter. Although the sun may seem less intense, its UV rays can still be harmful to your eyes. By choosing sunglasses with UV 400 protection, you can protect your eyes from long-term damage while still enjoying the joys of winter. So don't hesitate to put on your sunglasses the next time you head out in the cold!
