Complete Guide to Eye Drops and Artificial Tears
Understanding the Basics of Eye Drops
Many people think all eye drops are the same, but they actually serve different purposes. Some are plain moisturizers, while others are strong medicines. Knowing the difference ensures you treat your eyes correctly.
Eye drops are liquid medicines you place directly into the eye. Doctors use them to treat specific medical conditions. For example, our ophthalmologists may prescribe drops to fight infections, lower eye pressure for glaucoma, or stop swelling. Because these drops contain active medicine, you must use them exactly as directed to avoid side effects.
Artificial tears are a specific type of eye drop that you can buy without a prescription. Their main job is to add moisture to the surface of your eye. They mimic the natural tears your body produces. These are the most common treatment for dry eye, a condition that affects many patients in Marlton due to screen use and environmental factors.
Your eyes produce natural tears to stay clean and moist. These tears have three layers: oil, water, and mucus. If these layers get out of balance, your eyes feel gritty or burn. Artificial tears help restore this balance so your eyes feel smooth again.
Types of Drops for Different Needs
There are many bottles on the pharmacy shelf, which can be confusing. Here is a breakdown of the most common types of drops you might find or be prescribed.
These are standard artificial tears found at any drugstore. They come in liquid forms for daytime use and thicker gels for severe dryness. They are great for mild irritation caused by wind or reading. Our multispecialty team often recommends trying these first for basic eye comfort.
When over-the-counter drops are not enough, our ophthalmologists may prescribe stronger medication. This includes drops that help your eyes make more of their own tears (like Restasis or Xiidra). We also prescribe specific drops for glaucoma or serious infections. These require advanced medical care and regular check-ups.
During spring and fall in the Greater Philadelphia Metropolitan Area, pollen counts get high. Allergy drops contain antihistamines that stop itching and watering. While some are available over the counter, stronger versions require a prescription.
Drops that claim to 'get the red out' work by shrinking the blood vessels in your eye. While they make eyes look white quickly, they can cause more redness if you use them too often. This is called the 'rebound effect.' It is usually safer to treat the cause of the redness rather than just the symptom.
Many eye drops contain preservatives to keep bacteria from growing in the bottle. However, these preservatives can irritate sensitive eyes. Preservative-free drops usually come in single-use plastic vials. If you use drops more than four times a day, preservative-free options are much better for your eye health.
How to Use Eye Drops Correctly
Using eye drops the right way ensures the medicine gets where it needs to go without wasting it. Proper technique also prevents you from poking your eye or spreading germs.
Follow these simple steps for the best results.
- Wash your hands thoroughly with soap and water before handling the bottle.
- Tilt your head back and look up at the ceiling.
- Gently pull down your lower eyelid with one finger to make a small pocket.
- Hold the bottle over your eye and squeeze one drop into the pocket. Do not let the tip touch your eye.
- Close your eyes gently for one minute. Press your finger lightly against the inner corner of your eye near your nose to keep the medicine in place.
If you wear contacts, take them out before using drops unless the bottle specifically says 'safe for contacts.' Medicine can get trapped behind the lens and cause irritation. Wait at least 15 minutes after using drops before putting your lenses back in.
Keep your eye drops in a cool, dry place. Always check the expiration date. If you use a bottle with preservatives, throw it away about three months after opening it to prevent infection. Do not share your eye drops with friends or family members.
When to Use Eye Drops
Knowing when to reach for a bottle can stop minor discomfort from becoming a major issue. Here are common situations where drops help.
When you stare at a computer or phone, you blink less often. This causes your tears to evaporate. Using artificial tears during the workday can prevent 'digital eye strain' and keep your vision clear.
The weather in New Jersey changes drastically from humid summers to dry, cold winters. Indoor heating in the winter dries out the air, which dries out your eyes. Using drops during these seasonal shifts helps maintain comfort.
If you have had cataract surgery or other procedures with our ophthalmologists, using prescribed drops is critical for healing. We use advanced technology to perform these surgeries, but proper home care prevents infection and controls swelling during your recovery.
Frequently Asked Questions
Patients at ReFocus Eye Health Marlton often ask these questions about their eye care routine.
Yes, most people can use artificial tears daily. If you use them more than four times a day, switch to preservative-free drops to avoid irritation. If you still feel dry, make an appointment to see if there is a deeper issue.
Yes, eye drops expire. Using old drops is dangerous because bacteria can grow in the liquid. Always check the date on the bottle and toss it if it is past the expiration date.
It is best to put drops in before you apply mascara or eyeliner. If you need drops later in the day, be very careful not to let the bottle tip touch your makeup. This keeps the bottle sterile.
Some stinging is normal, especially if your eyes are very dry. However, if the stinging is severe or lasts a long time, you might be sensitive to the preservatives. Try a preservative-free brand instead.
Artificial tears are generally safe for kids, but you should check with a doctor first. Never give a child prescription drops that belong to an adult.
