Bifocal safety glasses , as self-explanatory by the name, are safety glasses with bifocal lenses. Such glasses combine the merits of both bifocal glasses and safety eyewear, answering the needs of many. On the safety front, these glasses are usually of lenses made with shatter-proof materials, such as polycarbonate, which make the glasses more durable and protective. In the meantime, the bifocal aspects of them provide the swift and smooth shift between close up vision and distance vision that suit the vision condition of many people. While most utility of bifocal safety glasses are for the safety and health of many special duty carriers that operate in unusual working environments, the functionality and usage of such glasses do stretch beyond the work place and into other fields, like many activities that people do at the comfort of their home.
For people who work in the industries that have the risk of being hit by flying debris or falling objects, safety glasses are an undeniable necessity. If he or she who works in such working environment also suffer from more than one refractive error, which require more than a pair of single vision glasses to cure, bifocal safety glasses come in handy. These glasses not only protect the wearers’ precious eyes from the hidden dangers of being damaged, they also give them the precise correction that is needed to guide them through their complex and sometimes minute work they are engaging in. Some industries may not have flying debris or things alike, but involve instruments or tools that could trigger radiation or biological hazards. For multi-vision-error sufferers working in such environments, bifocal safety glasses are the best choice out there, as well.
Home activities may be less associated with safety issue, yet dangers always come when least expected. Lathes, sanders, saws and other power tools may lead to serious damage to our eyes when they are in motion. As a result, if you use the listed tools, even in the seemingly safe environment of your home, you need protection from bifocal safety glasses, just as much as those who work at hazardous workplaces.
