Level 5 - mechanism / opinion, no new human data
Narrative review summarizing mechanisms and properties of physical photoprotection without a systematic review design.
PubMed 24891064 · doi:10.1016/j.det.2014.03.016
What was done
This narrative review synthesized knowledge on physical methods of ultraviolet radiation (UVR) photoprotection, specifically evaluating the protective characteristics of glass, window films, sunglasses, and clothing.
What was found
The abstract reports no numerical data. It notes that all types of glass generally block UV-B, whereas UV-A transmission varies depending on glass type, thickness, and color. Adding window films reduces UV-A transmission. UVR penetration through textiles is influenced by weave tightness, thickness, weight, fiber type, laundering, hydration, stretch, processing, UV absorbers, color, and fabric-to-skin distance.
Why it matters
It outlines the practical factors that determine how effectively common physical barriers—such as architectural/automotive glass and textiles—shield against UV-A and UV-B radiation.
Limits
The abstract provides only qualitative summary statements with no experimental data, effect sizes, transmission percentages, or systematic search methodology.
