 If dust strikes in your eyes you, must water your eyes almost five to six times a day.

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.

The third is too little sleep 

If you sleep too little in a day it causes red eyes too little sleep is not good for its side effect is that it's low your skin brightness.

 you will feel laziness all the time if you go to do any work then you will want to that work because of that you sleep too little your energy level in you have gone down.

It will decrease the amount of oxygen that reaches in your eyes due to it the small blood vessel dilates and become red your eyes if your eyes kept open long time because of lack of sleep it cornea (the surface of your eyes) from being well lubricated and this can cause dryness and redness.

Fourth is contact lens irritation  

Contact lenses causes of a red eyes because if your eyes want more oxygen then contact lenses prevent enough oxygen to reaching in your eyes and if wear contact lenses during sleeping then it also causes redness, infection in your eyes.
