Who need progressive bifocal safety glasses?
In the modern society, there are so many people who need to wear prescription eyeglasses or contact lenses. Another point is that many jobs or sports require the use of safety eyeglasses. This can be testified by the cases of eye injuries occurring every day worldwide. As the public enjoys a longer life span, many people in their 40s and 50s still remain in their jobs. However, the traditional problem called presbyopia is sometimes unavoidable. In this sense, this group of people needs both presbyopia correction and eye protection when they are involved in a dangerous activity. Bifocal and progressive bifocal safety glasses are the perfect solution for these people with special needs. Traditional bifocal safety glasses and progressive ones can both meet these two requirements, even though they are slightly different in lens design.
