Lasers can cause damage in biological tissues, both to the eye and to the skin, due to several mechanisms.

Another mechanism is photochemical damage, where light triggers chemical reactions in tissue.
March 9: Teams are allowed to begin negotiating with other teamsâ players who are set to become unrestricted free agents at the end of the league year. This is the first time the NFL is providing a window to negotiate with other teamsâ free agents prior to the start of free agency.

Unlike other leagues, the team that does sign a restricted free agent, which is hard to do, does not have to give up a draft pick or compensation.
