I was wondering what kind of eye protection is popular with students. Does it take a lot of time to get used to wearing? Speaking of visual hinderance, I always felt contact lenses provide superior vision and am reluctant to revert back to glasses. Assuming safety glasses offer sufficient protection from flying bits o' teeth, are there any regulations about contact lens use when treating patients? Thanks, Fred My dentist started using a face mask instead of safety glasses. What do you think works best?
