It’s been a great experience.I enjoy the freedom of not having to wear glasses or contacts during the day. Since CRT is at night, I don’t feel it and it doesn’t bother me at all. Also, it become part of my nightly routine, and takes barely any time to put the contacts in or take them out. It works really well too- I can go 3 days without wearing CRT and not have to wear glasses. Also, it’s great that my prescription hasn’t changed for 10 years ( my prescription was getting much worse every few months before I started CRT) so I can credit for saving my vision.
