What form of vision tests are done on I day? My son does not wear glasses (just one contact) and doesn't even have a pair. I know they are issued glasses on I day and in the PTR packet they asked for the prescription from the Eye Doctor ( I imagine to have a pair ready for him). If we need to send a pair we can but is there a point? I know once plebe summer is over he will go straight to contact again. Thanks for the help.
