Regular near and far viewing exercises can help prevent myopia and maintain vision health.
Getting sufficient vitamin A and lutein through diet is recommended before considering supplementation for maintaining healthy vision.

Maintaining Vision Health: Balancing Near and Far Viewing
Spending excessive time viewing things up close, such as smartphones, computers, and books, can contribute to vision deterioration and myopia. To maintain or improve vision, it is important to balance near viewing with far viewing. Spending at least one hour per day viewing things at a distance can help prevent myopia and maintain vision health. Getting outside for at least two hours per day, especially in sunlight, can also reduce the incidence of myopia. Additionally, engaging in smooth pursuit and near-far exercises can help strengthen the musculature around the eyes and promote lens flexibility, which aids in maintaining sharp vision at different distances.
Nutrition and Supplements for Vision Health
Vitamin A is essential for the photo-transduction cascade and maintaining healthy vision. Dark green leafy vegetables and liver are good sources of vitamin A. For those with age-related macular degeneration, supplementing with lutein, which is found in egg yolks, may help slow its progression. However, getting sufficient vitamin A and lutein through diet is recommended before considering supplementation. Red light exposure, particularly in the morning, may also offset some age-related vision decline.
Considerations for Corrective Lenses and Prism Lenses
Corrective lenses are necessary for those with impaired vision, but relying too heavily on them may hinder natural visual improvement. It may be beneficial to balance corrective lenses with intentional near-far viewing exercises and maintaining adequate nutrition. Prism lenses should be used cautiously as they can weaken eye muscles over time. Discussing exercises and alternatives with an eye care professional may be helpful for those with deviations or weaker eye muscles.
Improving Vision with Red Light Therapy
Exposure to red light, particularly early in the day, can potentially offset vision loss related to age-related macular degeneration and age-related visual decline. Red light devices emitting light in the 650-720 nanometer range may be used to improve vision. The duration of exposure should be short and not cause discomfort. This area of research is still emerging, and more studies are needed to fully understand the benefits of red light therapy for vision improvement.
Welcome to a preview of the sixth Ask Me Anything (AMA) episode, part of the Huberman Lab Premium subscription.
The Huberman Lab Premium subscription was launched for two main reasons. First, it was launched in order to raise support for the standard Huberman Lab podcast channel — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.
