With bifocal safety glasses, it is not necessary to wear reading glasses
underneath your safety glasses. They can provide vision for distance, or
uncorrected vision in the upper field and correction in the lower area
for
reading (or the inability to focus on nearby objects). The safety
glasses
provide a range of bifocal powers, fit and comfort, as do regular
bifocals.
UV protection is also available.
Most Americans 40 to 65 years of age require reading glasses, and many
also
need safety glasses in their line of work, when working on various
projects
at home or in recreational activities. About 10% of all persons who wear
safety glasses require bifocal safety glasses.
As in regular bifocal glasses, the magnification area of bifocal safety
glasses enables you to read fine print and see clearly. For example,
those
types of glasses work well for the construction manager who reads
blueprints
on the job site, since he must be able to read fine print, as well as
protect his eyes from hazards and obstacles at a construction site.
