Details: Taking care of your eyes has always been important, but as technologyand screensbecome more and more a part of our daily lives, were challenging our eyes like never before. The light from computers and the nighttime glow of smartphones can tire eyes, especially when youre looking at them constantly. Thankfully, its easy to support vision with carotenoids like lutein. As the principal carotenoid found in the macula, a central area of the retina, lutein plays a big role in supporting your sight. Specifically, lutein helps filter out the damaging blue light we expose ourselves to when using computers. In a study conducted in China with healthy subjects who regularly used computers, those who supplemented with Lutein had better contrast sensitivity in a visual performance test. Contrast sensitivity is a key factor in vision during low-light situations, such as night driving.
