Photo-Z or polarized?
They solve different problems, and the wrong choice is a daily annoyance.
Which one is for you
Photo-Z
Choose it when
One pair for the whole day, if you move in and out of buildings.
Its limit
Like most photochromics it reacts to UV, and windshields block most UV — so behind glass it will not reach full darkness.
Polarized
Choose it when
A second pair, if your bright hours are on the road, on water, or in open ground.
Made at 1.50, in green, brown or gray. Not offered with DRIVE CLEAR.
Its limit
It stays dark indoors, and some dashboards and screens can look dim or patterned through it. DRIVE CLEAR — the anti-glare coating for night driving — is not offered on a polarized lens; it goes on a clear lens or on Photo-Z, so the two are separate pairs rather than one.
The full reasoningRead less
Photo-Z is one pair for the whole day, ready from stock: clear indoors, dark in sun, and spin-coated so the color stays even at any prescription within its 1.56 range. Its limit: like most photochromics it reacts to UV, and windshields block most UV — so behind glass it will not reach full darkness.
Polarized is a true sunglass: permanently dark, and the only lens that kills reflected glare — the hard shine off water, wet roads, and glass. Its limits: it stays dark indoors, and some dashboards and screens can look dim or patterned through it.
Choose Photo-Z if you want one pair and move in and out of buildings all day. Choose polarized as a second pair if your bright hours are on the road, on water, or in open ground. Many wearers eventually own both — that is not upselling, it is what the physics supports.
