Not sure whether your lenses are truly polarized? Here are three quick tests — each takes under a minute.
1. The LCD screen test
Look at a bright LCD/LED screen (a phone, laptop, ATM, or car dashboard) through the lenses, then slowly rotate the glasses about 60–90°. Polarized lenses will darken or black out at certain angles; non-polarized lenses won’t change at all.
2. The reflection test
Find glare on water, glass, or a shiny car hood. Look at it with the naked eye, then through the lenses. Polarized lenses visibly cut the glare and reveal the detail underneath — tinted-only lenses just make everything dimmer.
3. The two-lens test
If you have a second pair of polarized sunglasses, hold one lens in front of the other and rotate 90°. Where they cross, the overlap turns almost black. Two non-polarized lenses stay clear.
Every Walleva polarized lens passes these tests. We also offer non-polarized and photochromic options — each product description states exactly which technology that lens uses.
