Having bright eyes can have a major impact on how well-rested you look, and on your overall impression. Lack of sleep or environmental irritants, such as smoke or fog, can cause the eyes to appear bloodshot or red. Over-the-counter eye drops contain the active ingredient tetrahydrozaline hydrochloride, which causes the blood vessels in the eyes to constrict, reducing the appearance of redness and making the whites look whiter.
Point your chin toward the air and tilt your head back while using your finger to pull down the bottom part of one eyelid.
Keeping your eye open, position the eye dropper above the middle part of the eye and squeeze out a single drop.
Close the eye and press the inner corner lightly with a finger to prevent the drops from draining out of the eye or into the tear-duct passages.
Repeat the steps with the opposite eye.
Repeat, if necessary, in each eye, applying one drop at a time and waiting five minutes between each application.
