We recommend you do the eye health exercises in the Better Eye Health Program™ once a day, five days a week to start. If you want to do these exercises twice a day please do. No harm. Some people find these exercises relaxing, and will repeat them if stressed, or before bed to help sleep. If you have a lot of extra time in your day to devote to eye health, we recommend adding other healthy activities like walking, yoga, Pilates, Qi gong etc. Anything you do to benefit your overall health will benefit the health of your eyes.
