Silicone lenses are a type of contact lens made with a silicone-based material, which allows for increased oxygen permeability to the eye. This can help reduce the risk of eye infections and improve overall comfort. Silicone hydrogel lenses are a specific type of silicone lens that also includes hydrogel, a water-absorbing material that helps keep the lenses moist and comfortable for longer periods of time. These lenses are popular for their breathability and comfort, making them a popular choice for contact lens wearers. **

Yes, you can apply new silicone on top of existing silicone as long as the old silicone is clean, dry, and in good condition.
