Besides eyeglasses for regular wear, there are still various types of specialty eyewear or “task-specific” metal glasses. Since one pair of eyeglasses does not fit all sizes in most cases, those specialty eyeglasses such as computer glasses, driving eyeglasses and protective glasses are helpful in specific circumstances. Computer glasses are particularly for long period or regular computer work. People wearing ordinary glasses develop computer vision syndrome symptoms such as eye strain and headache easily. Computer glasses are designed exclusively for intermediate vision during computer work, providing the best vision correction.
Some people may need special glasses for certain jobs or hobbies. For instance, ordinary bifocal glasses require wearers to look down trough the bottom part of the lenses to get close vision. For people who spend all day long on close reading, neck discomfort will surely occur. In this case, special-design bifocal and trifocal glasses named occupational bifocals and trifocals are needed. In addition, a separate pair of reading glasses is necessary for close-up work such as beading, needlepoint, crafting and so on.
Most sports require good visual acuity for satisfying performance, such as tennis ball, golfing and skiing. Sport-specific mens eyeglasses can both enhance performance and provide necessary eye protection. This type of specialty eyewear is often made of polycarbonate lenses, including skiing goggles, shooting glasses, swimming goggles and so on.
Glare reflecting off the road or the car’s windshield can be the cause of an accident because the driver failed to see the other car or a pedestrian. Driving womens eyeglasses including driving sunglasses and prescription glasses are needed to minimize the risk of accidents. Sunglasses for driving feature polarized lenses and prescription glasses for driving always have anti-reflective coating, which also aim at reducing glare.
People may also need safety eyewear to ensure their eye safety in dangerous situations. Safety eyeglasses including sports goggles and shooting glasses usually feature ultra-durability, a wraparound design, top and side shields. Some people may still like specialty eyewear just for fun and fashion.
