How long will a lens last or be effective?

Warranty is for one year.  However, with proper care and use, users have been known to extend the use of their Pinlock beyond the one year warranty. 

What does “Day Time Use Only” mean?

If you look at your helmet shield, it is marked with “VESC-8”.  This refers to a United States Standard for light transmittance for a single pane visor/shield.  All Visors/shields must meet certain standards, one of which is the transmittance of light.  

The requirement for motorcyclists’ eye protection is found in Section 7 of the Vehicle Equipment Safety Commission’s regulation VESC-8 adopted in 1971 and amended in 1980:

Section 7. Light Transmittance of Eye Protection Devices (EPD)

7.1 CLEAR – A clear EPD is a device which transmits not less than 85% of the incident visible radiation. 

7.2 TINTED – A tinted EPD is a device which transmits less than 85% of the incident visible radiation but not less than 20%. 

7.2.1  A tinted EPD shall not impair the wearer’s ability to discern color.

7.2.2 A tinted EPD shall not be used at night.

A shield may have less than 85% transmittance as long as it is not less than 20% and does not impair the ability to discern color.  Any shield that transmits less than 85% cannot be used at night and can only be used during the day time.  

Most shields/visors have a 90 – 91% light transmittance.  When you combine the shield/visor with another shield/visor or in our case with a Pinlock lens, the light transmittance will be reduced.  The combination of the Pinlock lens and shield will have a light transmittance range from over 20 % to a little over 80%.  Therefore, the requirement to place “Day Time Use Only” on the lens.  Pinlock does not impede the wearer’s ability to discern color.
