The Big Fish 1983 Gold Fish Trout Blue Sunglasses are sober and elegant, with a small curve of material on the sides to prevent light from entering. This model is fitted with non-slip nylon pads on the temples for better grip. Polarized lenses cancel out glare, contrast is optimized and reverberation glare is totally eliminated. The iridium blue Tri Acetate polarized lenses provide CE-standard UV400 protection against UVA and UVB rays, with an anti-scratch / Saltwater coating (reinforced anti-scratch surface treatment and protection against sea water). Ideal for days on the water in strong sunlight. Indispensable for sight-fishing and searching for fish on the hunt.
