how big the change is
No quantified outcomes yet. Once we have studies with measurable endpoints, you will see per-outcome magnitude here.
Wear sunglasses that block 99-100% of UVA and UVB rays whenever outdoors. UV exposure accelerates cataract formation, increases risk of pterygium, and may contribute to macular degeneration. Wraparound or large-lens styles offer the most protection.
This entry is in our database, but the research pipeline has not yet synthesized supporting papers. Evidence will update automatically as it's ingested.
How to do it
1Buy sunglasses labeled 'UV400' or '100% UVA/UVB protection'
2Wear outdoors year-round, not just summer
3Wraparound styles reduce side exposure
4Polarized lenses also reduce glare but don't add UV protection
5Children especially need UV protection (lifetime exposure matters)
Safety notes
Cheap sunglasses without UV protection are worse than none. Pupils dilate behind dark lenses, admitting more UV. Always check the label.
