Earlier this week, my eldest daughter sampled the local univ scuba course, both the lecture session and the pool session, and committed. (This is the same semester-long course I took in 1986, except with my instructor's then-assistant now teaching the course.)
First wet session: Determining the weight the students will use on their weight belt for the pool sessions, and being introduced to their masks and snorkels. First skills: Breathing off the snorkel, and mask clearing, including tossing their masks down the (shallow) swim lanes, and surface swimming to dive down to retrieve and clear their masks underwater. The first pool session ended with lap swimming (swim suits and maybe swim goggles, only). Exactly the same as my opening day skills.
My daughter wears contacts. I think she might have switched to eyeglasses for the pool session, except maybe removed the eyeglasses before entering the water--just as she did when swimming on the high school varsity swimming team a couple of years ago.
Don't worry. Just ask the instructor for his/her suggestions about this--or any--skill.
