Sun and glare in Fort Worth
In Fort Worth, UV reaches the high and very high categories from spring through fall and the sun is strong enough at midday that a hat and sunglasses are the normal uniform. Driving west in the late afternoon is the daily glare problem; polarized lenses cut it.
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.
