UV is MET Norway's clear-sky value with the hour's cloud taken out; the label is the WHO category. From 3 up, UV-rated sunglasses earn their place; glare (low sun, water, snow) is a separate question that polarized lenses answer.

Sun and glare in Memphis
Memphis is moderate most of the year; the index moves with summer UV and with a low sun in the shoulder seasons, when glare on a wet road is the daily reason for sunglasses. The hour-by-hour table shows when the UV is lowest.
How the index works
MET Norway gives a clear-sky UV index for each hour; cloud takes up to 70% of it away, so the number here is for the sky you have. The WHO categories: low 0–2, moderate 3–5, high 6–7, very high 8–10, extreme 11+. Eyes take UV damage at any category over time (cataract and pterygium are the documented ones), so a UV400 lens matters more than how dark it is. Glare is reflected light and peaks with a low sun, water and snow; that is the polarized question, not the UV one.
