Answer / Check:
-
Check for labeling: “100% UV”, “UV400” or “blocks UVA/UVB”.
-
Check the lens quality: good lenses do not distort the image.
-
LCD screen test: if turning the glasses in front of a screen (mobile, tablet) changes its brightness, it may be polarized.
-
Buy from reputable optical stores.
