Even if the eyewear market is filled with a huge variety of products in diverse styles in terms of both functionality and appearance, most people use regular glasses. It is an undeniable fact that a majority of eyeglass users buy eyeglasses because of a bothersome vision defect. Myopia glasses, hyperopia glasses and presbyopia glasses are regular products which deal with specific conditions. Most people use regular products in one of these categories. For instance, a pair of myopia glasses using prescription lenses will help rectify myopia appropriately. And hyperopia and reading glasses function in a similar way. For the vast majority of customers, these ordinary devices are enough. This is also the current situation in the eyewear market. However, it is also necessary to point out that these regular eyeglasses have some limitations, when certain additional functions and help are needed.
Regular glasses can only deal with one vision problem in terms of vision correction. But in some cases, getting proper visual aid is not enough. Prescription eyeglasses are also needed by many people in their workplace and even during outdoor entertainment. In these two cases, extra help from the glasses is very necessary. Sunwear products are very critical in protecting the eyes against hazardous UV rays, and safety eyewear is even a must during some risky tasks. Applying prescription glasses into these fields first requires the availability of related lens technologies. Until now, prescription eyeglass lenses are available in both tinted and safety types. Products of the first type are called prescription sunglasses or tinted eyeglasses, and the second type is safety Rx glasses.
These two compound forms of glasses have made related breakthroughs, which eliminate corresponding limitations of regular glasses. In detail, tinted eyeglasses can still offer proper UV protection, in addition to the regular function named vision correction. This functional combination is really significant for full-time users of Rx eyewear who like outdoor activities or sports. Safety Rx eyeglasses have an advantage over regular eyeglasses, because they can offer extra eye protection when the wearer is working in a dangerous environment or workplace.
