What Are Sandwich Technology Contact Lenses?

Sandwich Technology is a lens manufacturing process where the colored pigments are embedded between two layers of lens material, rather than printed on the surface.

How Sandwich Technology Works

1. A thin base layer of the lens material (such as Polymacon) is formed.

2. The cosmetic pigments are applied in the desired pattern.

3. A second layer of the lens material is added, completely sealing the pigments inside—like a “sandwich.”

Benefits of Sandwich Technology

1. Pigments Do Not Touch the Eye

The most important advantage is safety. Because the printed colors are enclosed between layers, the pigments never come in direct contact with the cornea, reducing the risk of irritation.

2. Consistent Color and Design

The embedded design remains stable, providing vibrant, natural-looking patterns without fading or flaking.

3. Smooth, Comfortable Surface

Since the pigment is internal, the outer lens surface stays smooth, contributing to comfortable colored contacts suitable for beginners.

4. Enhanced Durability

The sealed structure helps the lens maintain its shape and clarity throughout its recommended wear cycle.
