I started coming to Coffman Vision Clinic 9 years ago when I moved to Bend. I recommend them to abso... lutely everyone! Dr. Coffman is so detail-oriented and always striving to find the absolute best, most comfortable solution to your vision needs. He is who discovered I had astigmatism in both eyes after YEARS of me wearing glasses and no other clinics catching it. I also have to gush about how lovely Lara is; she is so patient and wonderful. I recently ordered some frames that I ended up being a bit uncomfortable in when wearing them for prolonged periods, so I scheduled an appointment to come in and talk options. She expanded on multiple different avenues we could go down, and also looked into the digital lens option for me on her own time prior to my appointment. So immensely thoughtful of her! You cannot go wrong coming to this clinic. You will be in the absolute best hands. ♡
