With access to more and better materials in the field of contact lenses, we are constantly making progress. Today, the greatest achievement in optical technology is contact lenses made of silicone hydrogel materials. What is their advantage over other solutions available on the market?
The origins of silicone hydrogel lenses go back to the 1960s and 1970s, when hydrophilic polymer technology was developed and soft contact lenses were produced. Large molecules resulting from the combination of repeated units were called hydrogels. Over time, these materials were paired with silicone materials, creating a new generation of contact lenses. These solutions are characterized by:
high clinical effectiveness,
high oxygen permeability, which provides greater comfort of use, better oxygen supply to the eye and the ability to wear lenses for a longer period of time – up to 30 days,
very good hydration, which increases the comfort of wearing contact lenses.
Wide range of choices
It is worth remembering that the catalogue of silicone hydrogel materials used in the production of contact lenses is very diverse. Individual types of materials from this group are available under different technical names, such as galyfilcon, comfilcon or senofilcon. Regardless of the specific material you choose, let’s see if your contact lens information is approved by the U.S. Food and Drug Administration (FDA). Then we’ll be sure they’re safe for the eyes.
