The foundation of O33 began with two doctors: Dr. Obby (Dr. Chompunoot Phumratprapin), an ophthalmologist with over 10 years of experience in eye health, and Dr. Tum (Kanaphon Phumratprapin), an internist and the founder of Health at Home, a home care service for the elderly and patients in need.

Both doctors deeply understand the importance of eye health and how it can transform lives. Their shared vision led to the creation of O33, an eyewear store that seamlessly integrates professional eye care expertise with a genuine commitment to delivering the best for others.
