Second is too much alcohol
Too much drink alcohol is the cause of red eyes. If you drink too many alcohols in a day then after the drink alcohol then you noticed that your eyes are dark red or next morning your eyes are too red in our eyes are very small vessels after the drink alcohol the blood vessel is dilated that’s why your eyes become dark red.
And if you want to adjust your eye then. I suggest that take an eye drop in your eyes can help to lessen the redness.
