Lubricating eye drops and gels improve the lubrication of the eye as the eyelid blinks over the front surface of the eye. A gel has a higher viscosity than a drop and comforts the eye for a longer period of time. The consistency of lubrication drops, and especially gels, may blur vision temporarily. Since your diagnosis requires the use of these lubricating products to comfort your eyes they may be used at regular intervals during the day, evening, and are especially helpful before bedtime. It is important to note that it is generally not recommend to use solutions that also include properties that claim to remove ocular redness.
