UV-blocking sunglasses are specialized eyewear designed to protect the eyes from the damaging effects of ultraviolet (UV) radiation. They are manufactured with lens materials or coatings that absorb 100% of UVA and UVB light, which means they completely prevent the invisible, high-energy rays from passing through and reaching the eye's internal structures.
read more about uv blocking sunglasses ...Many people confuse lens darkness with protection. A dark tint only reduces visible light, making you comfortable and causing your pupils to dilate (get bigger). If those dark lenses are not UV-blocking, your dilated pupils let in more unfiltered UV light, causing more damage. UV-blocking sunglasses are always marked with a UV400 or "100% UV Protection" label, regardless of the lens color.
Skipping UV protection can lead to serious eye issues over time. Long-term UV exposure contributes to the development of cataracts (clouding of the lens) and pterygium (a non-cancerous growth on the eye's surface). In the short term, intense sun exposure can cause photokeratitis, which is essentially a painful corneal sunburn.
For the best protection, look for sunglasses that wrap around the sides of your head. UV light can enter from the periphery and still cause damage. Wraparound styles or frames with thick, wide arms provide maximum coverage, protecting not just the eye but also the delicate skin around it, which helps prevent premature aging and skin cancer risk.
While Lens.com is your go-to source for contact lenses, we understand that complete eye health means full protection. We strongly recommend that all our customers pair their UV-blocking contacts with high-quality, UV-blocking sunglasses, especially during peak daylight hours, to ensure their eyes are fully shielded from every angle.
How do I know if my sunglasses are truly UV-blocking?
The only reliable way is to look for a sticker or tag that specifically says "UV400" or "100% UV Protection." If there is no label, assume they offer no protection. You can also have them tested by an optometrist.
Does polarization mean the sunglasses block UV?
No. Polarization is a feature that reduces glare from flat surfaces (like water or roads). It is a comfort feature, not a health protection feature. A lens can be polarized without being UV-blocking, so you must still check for the UV400 rating.
Should kids wear UV-blocking sunglasses?
Yes. Children's eyes have larger pupils and clearer lenses, allowing more UV light to penetrate to the retina. Starting early with 100% UV-blocking sunglasses is critical for their long-term eye health.
