In today's tech-driven world, the average person spends more than half of their day looking at a screen. Digital devices produce blue light and prolonged exposure that can cause eye fatigue and may even impact sleep patterns. The blue light from digital devices penetrates the macula of the eye. This portion of the eye is responsible for the quality and sharpness of your vision. Exposure to blue light may cause short-term effects such as eye fatigue and strain over time that can contribute to loss of ocular function. EyeScience Digital Blue Light Formula was created with heavy technology users in mind. The product may help reduce eye strain and fatigue, working from the inside out. The formula contains three integral carotenoids for the eyes which have been shown to cross the blood-retina barrier – Lutein, Zeaxanthin, and Astaxanthin (from Zanthin Astaxanthin Complex; Zanthin is a registered trademark of Valensa International). These three carotenoids may reduce oxidative stress on the retina cells, protecting the eyes.
