Do you experience dry eyes from time to time? If so, you’re not alone.

In fact, most people probably find themselves in need of eye drops every now and then. There’s nothing more uncomfortable than dry eyes, especially when you’re driving or doing anything else that requires focus and good clear vision.

After all, proper vision is incredibly important to daily life.

If you’ve ever wondered whether or not eye drops are safe, you’ve come to the right place for answers.

This article takes a look at what eye drops are safe after cataract surgery so that your eyes can stay as comfortable as possible. Keep reading to get the inside scoop.

What Do Eye Drops Do?

The basic purpose of eye drops is to add moisture to your eyes. That’s because when eyes become dry, this can cause irritation and redness. Thus eye drops are often needed to provide temporary relief until your eye can generate enough moisture on its own.

People use eye drops for a number of reasons, including use with contact lenses, cataracts, and when eyes dry out due to a variety of factors.

What are the Ingredients In Eye Drops?

The primary ingredient contained in most types of commercially manufactured eye drops is either Tetrahydrozoline or Naphazoline. The key thing to understand about these drugs is the fact that both effectively reduce redness from eyes. This is done through a process called vasoconstriction that artificially clamps down on the superficial blood vessels located on the surface of your eyeball.

You should be aware that with prolonged use, vasoconstriction can eventually result in extreme dilation, causing a person to need relief more often. Thus you should consult a doctor if the need for the use of drops becomes unusually frequent.

Are Eye Drops Safe to Use to Relieve Redness?

The short answer is “yes”. The key factor that you need to understand is that redness relief drops are intended only to provide short-term relief. Again, you should always contact your eye doctor if you feel the need to use drops on a frequent basis due to irritation.

How to Safely Use Eye Drops

It’s also important to understand the proper method for applying redness relief drops to dry or irritated eyes.

First, make sure that the bottle hasn’t been tampered with at the time of purchase. Next, never let the applicator come into contact with another person’s eyes. You should also never mix different types of eye drops. And you should only use eye drop as directed by your doctor.

Eye Drops Expire

Have you had a bottle of eye drops in your medicine cabinet for years? If so, you need to toss them out. That’s because the chemicals in eye drops degrade over a period of time and eventually change into harmful compounds. So always check the expiration date on the bottle before use.
