Sport or Work Safety Glasses?

When deciding between the two safety glasses options, it's best to start the decision process what environment you will be primarily using them in. In a nutshell, the ANSI standard is concerned with something breaking through the lens, making them great in the work environment. On the other hand, the ASTM standard is primarily concerned with lens dislodgement from the frame, a sport-focused standard.

What is the ANSI Z87.1 Standard?

ANSI (American National Standards Institute) Z87.1 is the standard required for occupational safety. In order to qualify for the ANSI certification, lenses must withstand the weight of a 1.1 lb pointed projectile dropped from a height of 50”. This is the High Mass Impact Test. In the second test, lenses and frames must withstand the impact of a .25” diameter steel ball fired at 150 FPS, the High Velocity Impact Test.

How to tell if a frame meets the ANSI standard?

Frame Markings :

  • “Z87” with a “+” marking shows the frame passes the ANSI High Velocity and High Impact testing
  • ANSI markings must be on each temple and the frame front

Lens Markings:

  • “+” shows the lens meets the High Velocity and High Impact Test
  • “S” shows the lens is a filter or shaded lens (not clear)
  • “V” shows the lens is a variable-tint photochromic lens

What is the ASTM F803 Standard?

ASTM (American Society for Testing and Materials) F803 is the safety standard for protective sports eyewear. When tested, the eyewear must withstand projectiles sized from 40mm to 65.1mm fired at a rate of 90 mph. All styles in Wiley X's Youth Force line pass testing for soccer, basketball, racquetball, squash, badminton, paddleball, tennis, and handball.

How to tell if a frame meets the ASTM Standard?


  • For prescription frames, frame must be marked with the manufacturer's name, frame style, and a date code.
  • For Plano (non-prescription) frames, they must be marked with the manufacturer's name and frame style.


  • Prescription lenses do not require markings but a lab slip that includes frame name, lens material, prescription, and lab info must accompany glasses.
