Administering droplets sounds simple enough, but there are things you should be aware of before and after you do it.
For one, you will experience blurriness after the substance makes contact with your eye. It will temporarily cover your cornea before absorption. Another thing is that your eyes need to stay closed for a few minutes, following a drop. If you don't close your eyes, the substance will spill. If you're in transit, park somewhere and give yourself enough time before you resume driving.
At this point, you should be aware of any allergies you might have. Check out the list of ingredients specified on the eye drop's label. Rule them out one by one until you're sure it won't cause you an even bigger problem. But if you start feeling dizzy or notice any swelling despite your efforts to be thorough, call emergency services.
Over-the-counter eye drops are good to have with you during travels. But remember that they contain preservatives and that doctors recommend four doses on any given day, maximum. If you opt to use an eye drop with no preservatives, understand that each bottle is for single-use only. After administering, throw the container in the garbage.
Of course, it would be ideal to have your doctor examine you thoroughly so that you won't have to experiment with different brands in the first place.
Any sign of an eye problem should prompt a visit to your optometry clinic Los Angeles, CA.
