ONOS of Ontario, California makes polarized sunglasses with discreet bifocal readers built right into the lens — no more swapping between sunglasses and reading glasses on the boat, the beach, or the road. Every ONOS frame below features 100% UVA/UVB protection, glare-cutting polarized lenses, and low-profile bifocals positioned 8mm below eye level, available in five reader strengths (+1.50, +1.75, +2.00, +2.25, +2.50) or plano with no reader. Anglers love them as fishing sunglasses with readers: spot fish through surface glare, then look down to tie a knot or read the finder — one pair does both. Styles range from sporty fishing wraps (Nolin, Nolin 2, Zoar) to women's frames (Cat Island, Sierra) and everyday unisex classics. M21 Sports ships ONOS sunglasses nationwide from Chino, California.
