[Description] This product contains bilberry-derived anthocyanins and lutein. Bilberry-derived anthocyanins help alleviate eye fatigue by improving the ability to adjust the focus of the eye, which is impaired due to the use of smartphones and computers, etc. Lutein is reported to supplement the macular pigment in the retina, which is believed to protect the eye from light stimuli such as blue light, and to improve contrast sensitivity (the ability to see clearly by eliminating blur and haze). Lutein has also been reported to improve contrast sensitivity (the ability to see objects clearly by eliminating blurring and blurring).
