Light and eye health are an often-neglected part of our overall wellness. While many of us focus on proper nutrition, exercise, and mental health, we rarely turn attention to the impact that light has on our well-being. This, despite the role that light plays in eye strain, seasonal depression, sleep disorders, sleep function, and sleep hygiene, among many conditions. Our guest today, Andy Mant, is here to shepherd us out of the darkness and into the (safe) light. His company, BLUblox, produces a range of light-blocking glasses. Their evidence-based, research-backed products and information focus truly sets them apart.

In today’s episode, we learn more about light blocking. We discover that blocking light is far more nuanced than we are led to believe. Light exposure is context-specific and solutions must deal with people’s specific circumstances. Andy also walks us through some ways to counteract overexposure to artificial light sources. We learn more about why sunglasses and sun cream are not all that they are cracked up to be and how they are potentially doing more harm than good. While this might seem counterintuitive, Andy’s got the research to back up the claims! This is a super interesting discussion on an aspect of our health that gets far too little credit. Tune in today.

“We wanted to become different from our competitors in that we are evidence-based. We use the academic literature to design our glasses.” — @andymant12 [0:14:34.1]

“Natural is the sun and artificial is anything that is in essence, emitting light during the day.” — @andymant12 [0:15:31.1]

“We’ve started to play around with those light signals by blocking them when we shouldn’t be, by partially filtering them when we shouldn’t be.” — @andymant12 [0:29:59.1]

“For us to have the perfect circadian health, we need to be outside exposing our eyes to the sun, regardless of whether it’s raining, cloudy, sunny.” — @andymant12 [0:40:07.1]
