Safety prescription lenses
When considering prescription safety glasses, it is important to know that one of the most significant parts of safety glasses are the lenses.
lthough polycarbonate is still the most commonly used industry standard lens, Trivex, a new advance in safety lens technology which meets the AS/NZs1337.6:2007, is now being used in more and more cases for improved optics and chemical protection.
- Improved impact resistance, more than polycarbonate
- Offer less distortion through the lens, leading to wider fields of view. Better peripheral vision for better for situational awareness
- 10% lighter than polycarbonate
- Signficantly higher resistance to chemical exposure than polycarbonate
- Can be tinted for prescription sunglasses up to 80% density tint
Another advance in prescription safety lens technology is the use of lasers to digitally cut and surface prescription lenses. These laser cut lenses, called “Free form “ lenses are now being used in more and more cases for improved optics and in safety glasses with high curvature or “wrap”.
- Lenses are ground, cut and designed with laser instead of standard machine lathes
- Laser design enables more customization and high definition optics, sharper vision. Any material such as Trivex, and any style of lens such and multifocal or single vision can be made with Freeform laser design.
- Creates automatically thinner, and therefore lighter more comfortable lenses
- Widens field of view and improves peripheral vision in all frames, in particular frames with significant “wrap/curvature” , leading to improved situational awareness by reducing blind spots.
