Eye drops are usually used to relieve temporary minor discomforts. If you are experiencing extended discomfort, you should contact your eye care professional immediately. Eye drops are good for getting rid of redness or itchiness caused by allergies or lack of sleep.
They can also be used for dry eyes caused by weather conditions or a lack of tears. Eye drops also are used to relieve ocular pressure and help prevent glaucoma by preventing the overproduction of tears or helping to remove fluids from the eyes.
Eye drops for allergies and redness usually contain antihistamines or an agent that keeps the eyes lubricated with tears. Due to the ubiquity of computers, eye drops for computer eyestrain are now widely available. These eye drops contain chemical agents that help relax the eye muscles and help with eye spasms.
When choosing an eye drop it is best to pick one that will relieve your particular symptoms. For people suffering from allergies, an eye drop containing an antihistamine is best. For people with dry eyes, lubricating eye drops are helpful. Some eye drops require a doctor’s prescription, so if you are not able to find an eye drop for your particular discomfort, it is a good idea to ask your doctor.
How to Administer Eye Drops
Although many people can administer their own eye drops easily, for others the task is not as simple. Whether you are using over-the-counter or prescription eye drops, use the step-by-step guide below to help you administer them correctly:
- Wash your hands with soap and water.
- Shake the bottle gently.
- Unscrew the cap.
- Tilt your head back and gaze upward at the ceiling; you can sit or stand.
- With your dominant hand, hold the bottle between your thumb and forefinger.
- Bring the bottle up to your eye.
- Using the little finger on your dominant hand, pull down the lower eyelid.
- While holding the bottle above your open eyelid, squeeze it so that one drop falls onto the eye.
- If the eye drop makes it into your eye, let go of your eyelid and close your eye.
- Repeat on the other eye.
To help you make the process smoother, remember to:
- Avoid letting the bottle touch your eyeball.
- Avoid letting the eye drops run down into your nose and throat. To do this, place the index finger of your dominant hand on the lacrimal sac (the small bump on the corner of the eye between the eye and nose). Hold your finger there for approximately two minutes.
- If you are unsuccessful the first time, try administering a second drop.
- If you are unable to administer the eye drops, ask a family member or friend to help you; inform your eye doctor of your inability to administer the drops.
- Try storing your eye drops in the refrigerator; the coolness of the drops can make it easier to tell when the drops enter the eye.
Prescription vs Over-the-Counter Eye Drops
Over-the-counter (OTC) or nonprescription eye drops can be found in most stores. In general, OTC eye drops are safe to use, as long as they are not used for prolonged periods. Some OTC eye drops contain chemicals that constrict the blood vessels, temporarily reducing redness on the sclera (the white part of the eye).
While these drops may bring temporary relief, once the effects wear off the eyes can return to their previous state, possibly redder than before. Allergic reactions have been known to occur in some people. Typically, preservatives in the eye drops are the culprit. For allergies, eye doctors recommend using artificial tears or preservative-free eye drops.
Both are sold over the counter and do not contain the chemical that constricts blood vessels. Artificial tears are also great for moisturizing. Lubricating gels and ointments, which are also sold over-the-counter, are good for overnight use.
Red or bloodshot eyes can be a sign of a more serious problem. Eye redness is not normal. If over-the-counter products are not effective, it may be time to see your eye doctor. Prescription eye drops are prescribed for various reasons.
Anti-allergy eye drops, such as Patanol, Livostin, Alomide, and Cromolyn relieve itchy, red, watery eyes by preventing the release of histamines. Anti-allergy eye drops are the most common eye drops prescribed.
Other types of prescription eye drops include antibiotics, corticosteroids, antiviral, anti-inflammatory, and drops to treat glaucoma.
If an eye infection is present, antibiotic eye drops are prescribed to treat and eliminate the infection. Corticosteroids are effective at treating puffy eyelids or iritis, but they can be dangerous to use. Improper usage of corticosteroid eye drops can result in cataracts or glaucoma.
These eye drops should be used cautiously under the direction of your eye doctor. If glaucoma is present, glaucoma eye drops are given to decrease excess pressure in the eye. Glaucoma causes the eye to produce more fluids than it can drain, causing pressure to build up.
The eye drops work either by decreasing the amount of fluid produced or by assisting the drainage process. These drops also need to be used under the direction of your eye doctor.
Antiviral eye drops such as are usually the primary treatment for the herpes virus. Triflurthymidine is often given in conjunction with oral medications to fight the virus.
