In this episode, Certified Bates Method Teacher, Nathan Oxenfeld interviews Dhruvin Patel who is an optometrist and a founder of Ocushield. His mission is to help eyes thrive in the digital age, so he has created a line of screen filters, glasses, and light bulbs that are designed to block blue light, which has been found to affect circadian rhythms and eye physiology.
