Big Fish 1983 Curve Fish Seabass Sunglasses are sober models featuring a slim frame with a slightly pronounced curve to prevent light from entering. Polarized lenses cancel out glare, contrast is optimized and reverberation glare is totally eliminated. Polarized lenses offer CE-standard UV400 protection against UVA and UVB rays, with an anti-scratch / Saltwater coating (reinforced anti-scratch surface treatment and protection against seawater).
