HEMA Contact Lens Explained: What It Is & The Brands That Use It

Not all contact lenses are made the same, and one big difference lies in the material. When comparing contact lens types, you may notice materials like HEMA, which stands for hydroxyethyl methacrylate, listed on lens packaging or product specs.

HEMA is one of the most commonly used materials in soft contact lenses. It’s been trusted for years and is still used by several well-known brands today. While it might not be the newest tech on the block, HEMA contact lens material still holds its own in terms of comfort and affordability, especially when compared with familiar hydrogel options like Etafilcon A contact lenses.

We’ll break down what HEMA contact lenses are, why some brands still use it, and whether it’s a good match for your eyes.

What Is HEMA?

HEMA, or hydroxyethyl methacrylate, is a type of soft plastic that absorbs water and becomes flexible. It was one of the first materials used to make soft contact lenses and has been around since the 1970s.

Higher water content can make a HEMA lens feel soft initially, but it may also lose moisture more quickly in dry, windy, or air-conditioned environments. HEMA also generally transmits less oxygen than newer silicone hydrogel contact lenses, which may make it better suited to shorter daily wearing periods.

The most appropriate material depends on your tear film, prescription, comfort needs, and wearing schedule. Your eye care professional can determine whether HEMA or silicone hydrogel contact lenses are better suited to your eyes.

How Do HEMA Contact Lenses Work?

HEMA contact lenses absorb water and remain soft while hydrated. Once placed on your eye, the flexible material conforms to the corneal surface and allows your tear film to spread across the lens.

Higher water content may give a HEMA lens a soft initial feel, but it can also cause the lens to lose moisture more quickly during long wear or in dry environments. This differs from other types of contact lenses that use silicone, rigid materials, surface treatments, or specialized moisture technologies to support oxygen flow and comfort.

Because HEMA generally provides lower oxygen permeability than newer silicone hydrogel materials, it may be better suited to shorter daily wearing periods. Follow your eye care professional’s instructions for wear time, cleaning, and replacement. HEMA describes the lens material rather than the replacement schedule, so some HEMA lenses are daily disposables while others are reusable contact lenses that are cleaned and stored between wears.

Pros and Cons of HEMA Contact Lenses

Like any lens material, HEMA contact lens material has its pros and cons. Here’s a simple breakdown:

Pros

Soft and comfortable for short-term wear
Usually more affordable than newer lens materials
Easy to handle and insert

Cons

Allows less oxygen to reach the eye compared to newer materials
May dry out more quickly during the day
Not designed for extended or overnight wear
