Five UV Protection Myths Your Eyes Want You to Stop Believing
Posted by Meridian Editorial on Jun 9 2026
UV damage to eyes is cumulative, painless while it happens, and linked to cataracts, macular degeneration, and growths like pterygium. It's also almost entirely preventable — if you can see past these five myths.
Myth 1: darker lenses protect more
Tint and UV protection are unrelated. UV blocking comes from the lens material and coatings, not the shade. A dark lens without UV protection is actively worse than bare eyes: the darkness dilates your pupils and invites more UV in. Look for "UV400" or "100% UVA/UVB" — every Meridian lens, from the Horizon Aviator to our clear optical demos, meets it.
Myth 2: clouds mean you're covered
Up to 90% of UV passes through light cloud cover, and scattered light on overcast days arrives from every angle. Your eyes take a dose on days you'd never think to reach for sunglasses.
Myth 3: winter is the off-season
Fresh snow reflects up to 80% of UV — nearly doubling your exposure by bouncing it up under hat brims and standard sunglasses. Add altitude (UV rises roughly 4% per 1,000 feet) and a ski day can out-dose a beach day. It's why Summit Snow Goggles treat UV blocking as seriously as fog.
Myth 4: kids don't need real sun protection
The opposite. Children's clearer lenses transmit more UV to the retina, and most lifetime exposure happens before 18. A real UV400 kids' pair like the Little Aviator is sun protection, not a fashion accessory.
Myth 5: only summer noon matters
UV to the eye peaks in mid-morning and mid-afternoon, when the sun sits at eye-slipping angles below hat brims. If it's bright enough to squint, it's bright enough to matter.
