Over 90% of these injuries are preventable with the right kind of PPE for eye protection. There are different eye protection options for your workplace designed for protection from laser radiation, flying debris, and chemical splashes.

These include laser and general safety glasses, goggles, face shields, and brow guards. Safety eyeglasses are the standard and bare minimum eye protection according to set ANSI standards. Unlike regular eyeglasses, they have a one-piece lens or side shield which wraps around the user’s temples.

Although generally associated with the manufacturing sector, safety glasses are used in many industries. The following are the characteristic features for safety eyeglasses for different applications.

Photochromic Safety Glasses

The lenses of photochromic safety glasses change to adjust to new lighting conditions. These glasses are hence the best choice for people who work indoors and outdoors since it negates the hassle of switching lenses for different areas.

The highest quality photochromic safety glasses change from a clear shade to tinted in about eight seconds and from tinted to clear in thirty-five seconds. ANSI-certified photochromic safety glasses also have an anti-scratch coating and block 99% of UV rays.

Warden Safety Glasses

These are the most common types of safety glasses since they are used for lawn work, tree trimming and in the construction sector. Their lenses are broader and thicker compared with conventional glasses, but they are lighter than other safety glasses.

The lens of warden safety glasses is made of polycarbonate and comes in various colours, including smoky grey, clear with an enhanced silver AR and wholly clear. The glasses come with a comfortable nose pad, non-slip grip and sometimes rubberised earpieces designed for ear protection and comfort.

Forensic Glasses

These are specifically designed for investigators and come equipped with a UV lamp. There are several types of forensic eyeglasses. The ideal choice for you depends on the material you are inspecting, its condition and the lighting of your environment.

There are three lens options available for forensic glasses based on how much reflected light you want to filter out of your work site. Red lenses transmit 2% light at 583nm; yellow lenses transmit 2% at 480nm while orange ones transmit 2% at 549nm.

Medical Safety Glasses

Medical safety glasses come with anti-fog coating, glare reduction, and polycarbonate lens and frames. ANSI-certified glasses also have a non-slip rubberised nose pad and temple bar for enhanced comfort.

Welding Glasses

Welding arcs generate a form of radiation called arc eye, which damages the eyes. As such, eye protection with the right lens’ shade is vital. The ideal shade number for your lens depends on your welding type. A rating of 2, for instance, suffices for torch soldering, while 14 is the minimum for carbon arc welding.

The safety glasses mentioned above should be replaced after every two years regardless of condition. Any replacement of damaged safety eyeglass parts should be done with those from the same manufacturer. This guarantees their preserved safety rating.
