Which sunglasses block UV rays? Summer is a time for fun in the sun, but it’s important to protect your eyes from the sun’s harmful ultraviolet (UV) rays. Overexposure to UV rays can damage your eyes, increasing your risk of cataracts, macular degeneration, and other eye problems.
Sunglasses are a great way to shield your eyes from UV rays. But how can you tell which sunglasses offer the best protection?
This article will guide you through everything you need to know about UV-blocking sunglasses. We’ll cover what UV rays are, the different types of UV protection, and how to choose sunglasses that keep your eyes safe.
Understanding Ultraviolet (UV) Rays
Sunlight is made up of different types of rays, including visible light and invisible rays. Ultraviolet (UV) rays are invisible rays that can damage your skin and eyes.
There are three main types of UV rays:
UVA rays:
These rays make up about 95% of the UV rays that reach the Earth’s surface. UVA rays can penetrate deep into the skin and eyes, contributing to wrinkles, sunburns, and cataracts.
UVB rays:
These rays are more energetic than UVA rays and can cause sunburn. They can also damage the cornea, the clear outer layer of the eye.
UVC rays:
These rays are the most energetic type of UV ray, but they are absorbed by the Earth’s atmosphere and don’t reach the surface.
Choosing UV-Blocking Sunglasses
When choosing sunglasses, it’s important to look for a label that says they block 100% of UVA and UVB rays. This will ensure that your eyes are protected from all types of UV radiation.
Here are some additional tips for choosing UV-blocking sunglasses:
- Look for a UV protection rating. A UPF (Ultraviolet Protection Factor) rating of 50+ is ideal for sunglasses.
- Consider the size of the sunglasses. Larger sunglasses offer more coverage and protection for your eyes and the delicate skin around them.
- Choose dark lenses. Gray, brown, and green lenses tend to offer better UV protection than yellow or orange lenses.
- Visor style sunglasses can provide superior protection for your eyes and the surrounding skin.
If you have any concerns about UV protection or your eye health in general, schedule an appointment with your eye doctor. They can help you choose the right sunglasses for your needs and provide additional guidance on protecting your eyes from the sun.

Understanding Lens Materials for UV Protection
Not all sunglasses are created equal, and the lens material plays a big role in UV protection. Here’s a breakdown of common lens materials and their effectiveness against UV rays:
-
Polycarbonate: This is a popular choice for sunglasses because it’s lightweight, impact-resistant, and offers 100% UV protection by default. Look for sunglasses labeled “polycarbonate lenses” or “impact resistant.”
-
Triacetate (TAC): This is another common lens material that offers 100% UV protection by default. TAC lenses are known for being scratch-resistant and relatively inexpensive. Look for sunglasses labeled “TAC lenses” or “triacetate lenses.”
-
CR-39: This is a lightweight plastic lens material that may or may not offer UV protection. It depends on the manufacturer. Look for sunglasses labeled “CR-39” along with “UV protection” or “100% UVA and UVB protection.”
-
Glass: Glass lenses can offer excellent UV protection, but they can also be heavy and shatter more easily than plastic lenses. Look for sunglasses labeled “glass lenses” along with “UV protection” or “100% UVA and UVB protection.”
Beyond UV Protection: Considering Other Lens Features
While UV protection is essential, there are other lens features to consider when choosing sunglasses:
-
Polarized lenses: These lenses reduce glare from reflective surfaces like water, snow, and pavement. This can improve your vision and make outdoor activities more comfortable.
-
Mirrored lenses: These lenses can add a stylish touch and further reduce glare. However, they can also make it harder to see in low-light conditions.
-
Transitions lenses: These lenses automatically darken in sunlight and lighten indoors, acting like prescription sunglasses.
By considering both UV protection and lens features, you can find sunglasses that are perfect for your needs and preferences.
Sunglasses for Every Activity
Finding UV-blocking sunglasses is easy when you know what to look for! Here are some tips for finding sunglasses for specific activities:
-
Everyday wear: Look for sunglasses with a classic style, like aviators or wayfarers, that offer 100% UV protection. Consider polarized lenses for added comfort outdoors.
-
Sports and outdoor activities: Wrap-around sunglasses with 100% UV protection and a snug fit will stay in place during movement. Consider shatterproof polycarbonate lenses for extra durability.
-
Driving: Sunglasses with polarized lenses can help reduce glare from headlights and oncoming traffic. Choose a style that allows for good peripheral vision.
