The science behind saline solution & its benefits

Contact lenses are a popular and affordable choice for many individuals seeking an alternative to eyeglasses. But committing to proper care of these tiny optical wonders is not quite as simple as using a microfiber cloth to remove the dirt from your grubby glasses. Ensuring the longevity of your contact lenses and optimal eye health while wearing them is crucial. So what is saline solution and what role does it play in contact lens care?

Let’s delve into the basic science behind saline solution for contact lenses to uncover the beauty of its composition and function:

What is saline solution?

Saline solution for contact lenses is a simple, pH-balanced saltwater solution containing approximately 0.9% salt. It is used to mimic the natural composition of tears, making it safe and gentle on the eyes. 

How does saline solution differ from contact lens solution?

While we do have an entire blog dedicated to answering this question, let’s unpack the basics below to alleviate any confusion when traversing the pharmacy shelves or searching online stores:

Multipurpose contact lens solution is used to cleanse, disinfect, rinse and store contact lenses. This solution may or may not contain saline.

While saline solution for contact lenses is safe to insert directly into the eye, contact lens solution is not. Multipurpose contact lens solution contains chemical substances such as hydrogen peroxide that may cause eye irritation, redness, inflammation and permanent eye damage if inserted directly into the eye.

When used in harmony, saline solution and contact lens solution become the ‘power couple’ of contact lens care. But they cannot be used interchangeably.
