Contact lenses are a popular and affordable alternative to eyeglasses, offering comfort and convenience. However, maintaining proper care is essential for both the longevity of your contact lenses and your eye health. Unlike cleaning glasses with a microfiber cloth, contact lens care involves more specialized solutions. This brings us to the importance of saline solution 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 for Contact Lenses?
Saline solution is a pH-balanced saltwater solution containing about 0.9% salt, designed to mimic natural tears. It's safe and gentle on the eyes, making it ideal for rinsing contact lenses before wear.

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.

  • To flush an unwanted object or particle out of your eye

  • To reduce eye redness

  • To aid in the removal of contact lenses if they appear to be stuck

  • To moisten contact lenses, reducing the risk of dryness and related discomfort and irritation
