You could be experiencing eye lag

Just as jet lag affects your levels of alertness and fatigue, overexposure to blue light can have the same effect on your eyes. Studies show that our eyes are extremely inefficient at blocking blue light from digital devices, which can impact the most sensitive areas of the eye — and can lead to blurry vision, dry eyes and headaches.1,2

Stay focused, sharp and more comfortable

Counteract prolonged blue light exposure with a physician-created eye health supplement formulated to significantly reduce eye strain to help your eyes perform optimally, despite increased screen time. Just two daily capsules can provide long-lasting blue light relief for people who spend much of their day looking at screens.*

  • Reduce eye strain*

    Improve your ability to adjust to bright light conditions, judge distance, and distinguish different objects onscreen.

  • Preserve mental focus*

    Reduce eye fatigue and headache frequency so you stay alert and focused on the task at hand.2

  • Help fight insomnia*

    Offset blue light that can suppress the secretion of melatonin, a hormone that can affect your ability to fall asleep.2

High Definition caught my attention because I am on my computer all the time for online classes and gaming. After trying it out, I feel like my eyes can focus better and don’t feel as strained. Would definitely recommend it.

High Definition is a really good product. After a few days I could tell a difference in how my eyes reacted to looking at screens for an extended period of time.
