Darkness ≠ protection
A dark tint with no UV filter is worse than no sunglasses at all — your pupils dilate behind the dark lens and let in more harmful UV. Always check the label.
What to look for
- UV400 or 100% UVA/UVB — the only labels that matter for protection.
- Polarization cuts glare from water, snow, and roads. Great for driving and the beach; not strictly a UV feature.
- Lens category 3 is the everyday sweet spot for bright sun.
Caring for the coating
Rinse with water before wiping, use a microfibre cloth, and store in a hard case. Paper towels and shirt hems scratch coatings over time.
