Dispensing第 67 / 100 题
A photochromic lens is a poor choice for a patient who wants dark lenses primarily where?
a.Inside a car (windshield blocks UV)
b.Outdoors on a sunny day
c.In the snow
d.At the beach
解析
Because most photochromics activate with UV, and car windshields block much of the UV, the lenses stay relatively light while driving. A polarized or fixed-tint sunglass better serves in-car darkening.
