You are correct in trying not to use your glasses as long you don't risk your health or others. Trying to go without glasses is helpful as long as you learn to do things differently-proper breathing, relaxation, palming, etc. Just taking your glasses off and still using "bad" visual habits will not help nearly as much.

I am an optometrist, natural vision care specialist and syntonic (color light)practitioner as well as a SFQ student. If you would more info on this just let me know!
