Advantages of non-ionic cosmetic contact lenses vs silicone hydrogels: which is better?

Non-ionic cosmetic contact lenses are also a type of cosmetic contact lenses. A lot of people know about them. So what are the advantages of non-ionic cosmetic contact lenses? Which is better, non-ionic contact lenses or silicone hydrogels?

Advantages of non-ionic contact lenses

The biggest advantage of non-ionic material is that it is not easy to accumulate protein precipitation, and the contact lens itself has anti-precipitation properties. The principle is that because the lens itself is not charged, it is not easy to adsorb protein precipitates, thereby reducing the accumulation of protein precipitates. On the contrary, ion-type lenses are prone to accumulate protein deposits, especially when worn for a long time, which can easily cause symptoms such as eye redness and discomfort. At the same time, ionic materials are easily affected by pH changes, which can also cause changes in lens parameters. However, compared with non-ionic materials, ionic materials have better wettability, can maintain the moisture and comfort of lens wearing, and tear protein denaturation is less. In terms of comfort, non-ionic lenses are more popular among consumers and their popularity is increasing.

Which is better, non-ionic contact lenses or silicone hydrogels?

1. Non-ionic material suitable for sensitive eyes.

2. Silicone hydrogel material suitable for dry eyes.

First of all, we must distinguish that sensitive eyes and dry eyes are two completely different concepts. Sensitive eyes refer to sensitive eyes that are prone to foreign body sensation/presence and red bloodshot when wearing most lenses. Dry eye syndrome refers to dry eyes that are prone to dryness and discomfort when wearing contact lenses.

The advantages of non-ionic cosmetic contact lenses have been introduced here. Now you know which one is better, silicone hydrogel or not!
