EYE PROTECTION
ОглавлениеWhen choosing eye protection, know your hazards and understand the available lens materials. Generally speaking, eye protection falls into two categories: safety glasses and safety goggles. For some tasks, you may also consider a full-face shield like those used for chainsaw operation.
Safety glasses and goggles are made from numerous types of lens material, and it helps to understand the differences between them.
Polycarbonate offers excellent impact and scratch resistance, is lightweight, and can offer some protection against ultraviolet rays. The downside to polycarbonate would be that its optical clarity isn’t as great as NXT polyurethane or optical glass.
NXT polyurethane (Trivex) also offers excellent impact resistance, has premium optical clarity, and is lightweight. Its downside would be the higher price tag, but some would argue that having better optical clarity is worth the investment because being able to see well could help to prevent other injuries in the shop.
Acrylic lenses are often the most inexpensive. They are not very durable, nor do they have very good optical clarity, but they are resistant to solvents.
Optical lenses are choice for those who prefer prescription glasses. They often have excellent scratch resistance and offer distortion-free vision. The downside would be that they are heavier and come with a higher price tag. Generally, they additionally have poor impact resistance.
