The bi-focal safety specs glasses allow the user to...show moreread and look at distant objects without the need to remove or glance over the top of the glasses. This is because these bifocal eyeglasses have a lower lens section that corrects near vision focusing problems whilst the upper section is a plain lens without any corrective power.

The lower corrective lens section is a D-shaped segment that is fused onto the surface of the main lens area. The dioptre values available for the reading lens start at +1.0 dioptre and increase in half dioptre steps up to +3.0 dioptre.
