HEMA-Copolymer

HEMA-Copolymer Contact Lenses

The HEMA-Copolymer material is commonly used in the manufacturing of contact lenses. These lenses offer a moisture content of 38%, providing comfort and hydration to the wearer. The HEMA-Copolymer lenses have an oxygen permeability of 23, allowing for adequate oxygen flow to the eyes.

Here is a list of contact lenses made from HEMA-Copolymer:

• Queen's Solitaire Toric: Toric 3-month lenses made by Soleko, Moisture/Water content: 38%, Oxygen permeability: 23
• SeeOne 58 Tageslinsen: Spherical daily lenses made by Lenscare, Moisture/Water content: 58%, Oxygen permeability: 23.6

Comparatively, the water content of HEMA-Copolymer lenses falls within the mid-range when compared to other contact lens materials. For instance, materials like Aerofilcon A and Alphafilcon A have higher water content, while Balafilcon A and Copolymer have lower water content.
