• FLEXIBLE FRAMES & NOSE PIECES : These bifocal glasses are extremely lightweight and flexible, so they conform nicely around your head. You can wear these bifocal eyewear for hours while playing 18 holes of golf and not even notice they are on. Soft rubber nose pieces prevent slippage, so these bifocal glasses are perfect for cycling, tennis, baseball, running, motorcycle riding, driving and golf.
• 100% UV PROTECTION : Always wear sunglasses with 100% UV protection. Sometimes you will see “UV400 protection” which means the lenses will block UV light up to 400 nanometers (all UVA & UVB rays) on the UV spectrum. Prolonged exposure to the sun’s harmful UV rays can cause cataracts, pterygium and corneal sunburn.
• NON-SLIP RUBBER NOSE & EAR PIECES : If you want to be on top of your game, you need sunglasses that don’t slide down your nose, or fly off in the wind. If you to start to sweat, ordinary plastic nose pieces can hinder your performance. Rubber nose and ear pieces are soft and comfortable. Spend more time focusing rather than adjusting with these sunglasses.
• NEAR INVISIBLE BIFOCAL LINE : Everyone will need to wear bifocals at one point in their lives. But does the whole world need to notice those unsightly bifocal lines? The magnified reading area at the bottom of the lens is injection molded, which means you can’t feel the bifocal line on the lenses. The front of the lens is smooth, like nothing is there. It’s nearly invisible. It’s visible from the back of the lens, however, but not so much on the front of the lens.
• WHAT ARE BIFOCALS? Bifocals have a distinct magnified area at the bottom 1/3 of the lens separated by a line. The top area has zero magnification. Small objects like small print are magnified when looking through the bottom of the lens. When looking straight ahead, the vision is normal. Available in the following powers: 1.00, 1.50, 2.00, 2.50 or 3.00. Always round up if you are X.25 power.
