The ingredients and composition are effect as supplements to improve the eye vision I suffer from fatigue in eye and blurry sight maybe because I spend time in front of computer. the size is fine for one month the quality good 👍 and packaging is perfect. 自从眼睛开始接触手机荧幕闪光加深了许多,加上白天工作需要八个小时都对着电脑荧幕,希望这个能够缓解眼睛疲劳问题。 Pls like if my review helped.
