Outdoor lovers need UV protection, anti-glare and better contrast. Flat surfaces create disturbing glares that regular sunglasses cannot fully block. Giofine polarized lenses eliminate glare, boost contrast, deliver true colors and clearer vision.

Frequently Asked Questions
How do polarized lenses work?
Polarized lenses contain an embedded polarizing film that blocks horizontally reflected glare from flat surfaces — water, roads, snow — while allowing vertically oriented light through, giving sharper contrast and true colors.
What is the difference between polarized and regular sun lenses?
Regular sun lenses only darken light. Polarized lenses additionally eliminate reflected glare, which reduces eye fatigue and improves depth perception in bright outdoor conditions — ideal for driving, fishing and water sports.
Which indexes and colors are available?
Polarized lenses come in 1.499, 1.60 and 1.67 indexes with grey, brown and green tints in solid or gradient styles, with UC, HC, HMC and mirror coating options.
Can I get prescription polarized lenses?
Yes — polarized lenses are available as finished plano and prescription lenses, and as semi-finished blanks for in-house RX surfacing.
