Glasses are often used to correct eye vision problems, or to provide safety by protecting against problems. Sometime, in the case of prescription sunglasses, they may do both.
- Safety glasses protect the eyes when doing wood, metal or industrial work. These are just plain clear lenses, but very useful.
- Safety glasses with inbuilt lights. These do exist and are quite useful. Hands free operation in the dark. Never have to worry about damaging your eyes when looking though an attic.
- Amber lens driving glasses. Driving glasses were once as essential for cars as helmets were for motorcycles. The amber lens was thought to cut haze at a distance.
- Welding glasses. These were once just dark. Now there are glasses and helmets that change when a sufficiently bright light is sensed.
- Yellow lenses. Prone to melancholy? Especially during the winter seasons? Yellow glasses make the world look like a sunny day. The depressed person may be reluctant to initially put them on. But the effect is palpable.
- Orange lenses. For late night wear. Blue light keeps us awake, and this included computer screens or mobile phones. Lenses that block blue light, when worn late at night, can make all the difference.
- Polarized lenses. Mostly seen on sunglasses, these are very effective for reducing glare, which increases visibility. Used by pilots and some drivers.
- Google glass or smart glasses. Displays useful computer information to the wearer.
- Deep optic glasses. These automatically sense where the viewer is looking, at a near object or far, and adjusts the focus of the glasses accordingly. This is incredibly useful for individuals with complex eyesight problems, or those who cannot keep changing their glasses.
