How to choose an appropriate eye protector?

 

1. Choose a qualified eye protector tested relative test standards

  Eye protectors, such as sunglasses, googles, safety spectacles, safety googles, are Personal Protective Equipment (PPE) against risks of eye injury. Below are known relative test standards for reference:

 

Sunglasses, fashion spectacles, goggles – cosmetic, fashion, in general use

EN ISO 12312-1 (EU)

ANSI Z80.3 (US)

AS NZS 1667 (AU/NZL)

Military spectacle, goggle and hybrid goggles – provide highest eye protection for soldiers, law enforcement, airsoft players.

MIL-PRF-32432A (US)

 

2. Frame material

  • Made with appropriate materials of aspects as follow:

  • Lightweight – Stress-free fit

  • Strength - Good chemical (e.g. solvent) resistance and stress-crack resistance

  • Durability - No deformation under high environmental temperature

  • Flexibility – High flexural fatigue strength

  • Safety - Not easily to melt or burn in high temperature

  • Anti-slip nose and tips – good retention on the face

 

3.  Fitness

  • Choose the appropriate size for your face – stress-free, good retention while wearing.

  • Integration of Human Factor Engineering (HFE) in design and construction – comfortable fitness, lenses not too close or too far from eyes, lower the fatigue and stress of eye, prolong the time of wearing eyewear

  

4. Lenses

  • The lenses for outdoor activity and general sports use are best to have below features:

  • Lightweight, shatterproof material provide appropriate protection against mechanical hazards

  • Complaint relative test standards of optical requirements of Plano lenses to reduce eye fatigue and stress

  • Filtering bad influences of sunlight, for instance, UV rays, blue light, sunglare.

Choose appropriate filter category of visible light transmittance, see below table of EN ISO 12312-1:
