About Lois (admin)

I've lived with strabismus over half a century. Also called crossed eyes, lazy eye, turned eye, squint, double vision, wall eyes, floating, wandering, wayward, or drifting eyes, approximately 1 in every 25 to 50 people suffers from this condition. Strabismus not only affects vision. Many suffer social embarassment, lost job opportunities, and a host of other problems. Yet, living with eyes apart forces us to adapt, meet the challenge, and become stronger.
