Yes, all Revant prescription lenses are designed to meet ANSI Z87.1* standards for high mass and high velocity impact resistance.
*All prescription lenses meet the ANSI Z87.1 tests for clarity and high impact resistance, but not all frames are designed for high impact. Your frame must also be marked with “Z87” to comply with the ANSI standards and be approved by the Occupational Safety and Health Administration (OSHA) for use in environments where eye protection is required.
If your frame has a Z87 mark indicating that it is impact rated, your prescription lenses will have “R+” etched into an upper corner. This is because ANSI Z87.1-2010 standards require that prescription lenses that are impact rated be etched with the manufacturer’s logo (“R” for Revant) and the impact mark (“+”).
