Silicone Hydrogel Contact Lenses vs Hydrogel: What’s the Difference?
“Hydrogel and “silicone hydrogel.” They may sound similar, but these materials actually represent two different generations of contact lens technology.
So how are they different? The short answer is that silicone hydrogel contact lenses let much more oxygen through to the eye than traditional hydrogel lenses.
That’s why most modern soft contact lenses are now made from silicone hydrogel materials.
But if silicone hydrogel is newer, does that automatically make it better? And how exactly are the two materials different? Let’s take a closer look.
