I cannot thank Dr. McBryar and all of us so much. The 'bi-temporal 15 diopter fresnels' glasses have made all the difference in the world, like the difference between daylight and dark. My Charles Bonnet hallucinations remain greatly reduced and it gives me so much relief and peace of mind during the day and when I go to sleep. I was even able to see large words on the TV now, and when I told my grandson that I could see his face, he started crying. I wear the glasses everywhere I go. I am a "very happy camper". Thank you, thank you, thank you!
