It is understandable of their functions from the name of bifocal safety eyewear. They can meet both needs of people with presbyopia and at the same time, with need to protect eyes from possible harm. One is visual compromise and the other is eye protection. In fact, bifocal safety glass is neither a sole nor a strange member in the large family of eyewear products. 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 eye protection, which has been traditionally guaranteed by protective eyewear or special goggles. Statistics show that about 75 million pairs of Plano or non-prescription safety glasses are sold each year in the United States alone. 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.
The other major point is 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.
If your doctor told that you need to correct vision with bifocal glasses, and you at the same time, you need to protect eyes, bifocal safety eyewear may be the most economic and effective solution for you.
