There are some new rules about tinting and shaded glasses in the latest team update (and discussion here:
http://www.chiefdelphi.com/forums/sh...threadid=52592)
3.3.4 NEW: Mandatory Safety Glasses - They aren’t forehead protectors
NEW: FIRST requires all teams to bring and supply, for each competition, ANSI-approved nonshaded
safety glasses for its team members, mentors, and guests.
For our purposes, amber lenses that allow for better/brighter vision are considered tinted, not
shaded, and their use is allowed at FIRST events. Sunglasses or deeply shaded safety glasses
used in our indoor event environment are not acceptable.
Students and adult team members and guests must wear approved safety glasses when:
- NEW: Entering the Pit
- Uncrating the robot
- In the Pit, everyone must wear them at all times
- Working on the robot
- When observing any robot building/repair work
- While competing – mentor, human player, 2 operators
Operators, players, and mentors will not be allowed on the competition field without approved safety
glasses. Regular glasses do not qualify as safety glasses, and you must use approved safety
goggles over them. Goggles are not required over glasses if the glasses are ANSI-approved with
side shields.
I would presume that it would be best to get z87+ certified glasses.
