Are My Sunglasses Giving Me Enough UV Protection?

Not all sunglasses are created equal, especially when it comes to protecting your eyes from the sun’s damaging rays. It’s important to ensure that your pair offers adequate UV protection to safeguard your vision. This guide will help you determine if your sunglasses are up to the task.

Understanding UV Radiation and Your Eyes

Ultraviolet (UV) radiation from the sun can harm your eyes and affect your vision. Conditions such as cataracts, macular degeneration, and even certain cancers can be linked to UV exposure. Therefore, sunglasses that block 100% of UV radiation are essential for preventing these harmful effects. In areas where the elevation can intensify the sun’s effects due to thinner air at higher altitudes, choosing the right sunglasses is even more critical.

How Much UV Protection Should Sunglasses Have?

Ideally, your sunglasses should offer UV 400 protection, meaning they block light rays with wavelengths up to 400 nanometers, covering all UVA and UVB rays. The label on your sunglasses should indicate 100% protection against both UVA and UVB or UV 400. If the label doesn’t clearly state this, consider looking for a new pair that does.

The Truth About Dark Lenses

Many people mistakenly believe that darker sunglasses provide better UV protection. The tint of the lens has no impact on UV protection. Dark lenses without UV protection actually pose more risk, as they can cause pupils to dilate, allowing more UV rays to enter the eye. When shopping, make sure that your choice is based on UV protection, not just lens color or darkness.

Testing Your Sunglasses for UV Protection

If you’re unsure about the level of UV protection your sunglasses provide, there are a few ways to test them:

• Professional Testing. The most reliable method is to have them tested by an eye care professional. Bring your pair by our office and we can verify the amount of UV transmittance using one of our instruments.
• UV Flashlight Test. A simple at-home test involves using a UV flashlight. Shine the UV light through the lenses onto something that would normally fluoresce, such as a banknote. If the item fluoresces, your sunglasses likely don’t offer adequate UV protection.
• Labeling. Always check the labeling when purchasing sunglasses. Look for indications of 100% UVA and UVB protection. Reputable brands will label their products accordingly.

Where To Shop for Sunglasses

When looking for sunglasses with proper UV protection, consider visiting local optometrists and eyewear retailers. These locations often carry a range of sunglasses that meet the necessary standards for UV protection. Additionally, shopping locally allows you to try on various styles and fits, ensuring not only protection but comfort and style that suit your personal preferences.
