Silvana Polarized Sunglasses
Floating polarizing sunglasses. Gray lenses
Polarizing, floating sunglasses, tailored to the needs of anglers!
A pair of sunglasses is made up of a frame and lenses that have light filtration properties. Our frames are made of thermoplastic polymer among the lightest on the market (0.83g/cm3). It’s an environmentally friendly choice that offers great comfort, mechanical resistance to shocks, to cold, to bending fatigue, and to solvent corrosion. This material also has good elasticity. An additional advantage of these frames is that they make them float!
The filtering properties of the lenses must guarantee on the one hand filtration of visible light and on the other hand sufficient filtration of ultraviolet (UVA and UVB) as they can be very dangerous for the retina. All our lenses are rated category 3 (which lets through 9 to 18% of the light) except the yellow lens in category 2 (which lets through 43 to 19% of the light). Our lenses comply with the UV 400 standard: Total filtration of UVA and UVB. The polarizing filter absorbs 95% of glare. Anti-scratch/sea-water resistance surface treatment of the polycarbonate.
Basic lens colors:
Dark colors like gray are ideal for everyday use in most outdoor activities under bright conditions. Skiing, sea fishing, lake fishing. Gray lenses do not distort colors.
Light colors yellow and amber excel in moderate to low light conditions. Excellent depth perception, improve contrast, make the environment brighter. Surfacing or mirror coating refers to a reflective film applied to the outer surfaces.
• The white mirror (silver) is the most versatile and suits many situations
• The Ice blue Revo mirror (blue) helps define contours and color perception
• The green Revo mirror (blue/green) improves contrasts and reduces eye fatigue in high brightness and long sun exposure.
• The Red Revo mirror (yellow/red) cuts glare and reduces eye fatigue.
