Prescription sunglasses and prescription goggles are both special types of eyewear that come in a similar design principle. For instance, prescription sunglasses provide both single vision correction and UV protection and prescription goggles or safety glasses offer single form visual aid as well as eye safety guarantee. Comparing these two types of combinational products, bifocal safety glasses have more similar points with prescription goggles.
When it comes to vision correction, bifocal safety reading glasses are supposed to be as competent as regular bifocal reading glasses. Each year there are millions of people in the United States and across the world who enter their 40s, which suggests the use of reading glasses or bifocal reading glasses. This is really a great number of potential customers. Bifocal safety glasses will offer equal vision correction brought by regular bifocals. Users of these glasses can get vision aid against presbyopia. This is one of the major points of bifocal safety spectacles.
The other major point is eye protection, which has been traditionally guaranteed by protective eyewear or special goggles.

This kind of eye safety guarantee is quite necessary for a considerable portion of all presbyopic patients when they are participating in certain activities or sports. Foreseeing this significantly unfulfilled need, there are some manufacturers providing bifocal safety eyeglasses.
