Red light glasses

Red lens glasses, designed to be worn in the evening, are intended to filter out short wavelength light from screens and LED lights, preventing melatonin suppression and aiding sleep. These glasses differ from traditional blue blockers as they address a wider range of light wavelengths that can disrupt sleep patterns at night 1.

In a broader context, Andrew Huberman also discusses red light therapy's potential benefits for vision and mitochondrial function, particularly in aging populations. Studies have shown that brief morning exposure to red light can improve mitochondrial function in photoreceptors, potentially slowing vision degradation linked to aging 2 3. This therapy involves using red and near-infrared light, which has been found to reduce reactive oxygen species and cholesterol deposits in the eye, leading to improved neuronal health 4.

These insights suggest that while red light or red lens glasses provide numerous benefits, they are most effective when used appropriately and in the right context, particularly in minimizing exposure to certain light wavelengths in the evening to foster better sleep and potentially supporting eye health.
