Strongest in Recency (100). Held back by Sample size (5).
Solid mix of RCTs with some methodological gaps.
Few independent replications; results not yet robust.
Small combined sample; treat as preliminary.
Mixed direction across studies.
Most studies are recent (last 2-3 years).
No per-outcome numbers yet for this one. Each finding's direction and strength is shown in the research below.
Areas where research points to a consistent direction of effect. The strength of evidence is graded; the size of the effect is not quantified.
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.
The strongest clinical evidence for photoprotection against visible light-induced skin damage concerns natural sources of polyphenols.
