It may not be common knowledge, but the sun’s ultraviolet (UV) rays can also damage your eyes. This is why you should wear sunglasses every time you go out. If you wear contact lenses, these can also provide UV protection — but are they enough?
Read on to learn more about contact lenses and UV protection.
What You Should Know About Ultraviolet Light
UV radiation is classified into three types: UV-C, UV-A and UV-B. UV-C radiation is harmless because the ozone layer absorbs it. UV-A and UV-B radiation, on the other hand, can cause long-term eye damage and affect your vision after constant exposure. Prolonged exposure to UV can lead to various eye conditions. That’s why you should always protect your eyes with UV-blocking eyewear whenever you’re outside.
How Can Your Contact Lenses Help?
Contact lenses can have UV-blocking properties. And since they are worn directly on the eyes, they can be an effective way to protect your eyes from UV. However, not all contacts have a high capacity to protect your eyes against UV.
For example, FDA Class 2 contact lenses can absorb more than 50% of UVA and 95% of UVB. These lenses are typically recommended as all-purpose UV-blocking contacts. In a high-exposure environment, such as the mountain or beach, FDA Class 1 contact lenses are recommended. Contacts in this category can absorb more than 90% of UVA and 100% of UVB.
UV protection lenses must be considered by those who lead an active lifestyle, particularly those who spend long periods outside. However, contact lenses cannot protect your entire eyes. To shield your eyelids and the skin surrounding your eyes, you still wear UV-protective sunglasses in addition to your contact lenses.
