Are silicone hydrogel contact lenses good to use?

Silicone hydrogel contact lenses have several advantages that make them a popular choice for many people. Their main feature is high oxygen permeability, which allows the eyes to breathe more freely and ensures better eye health. Silicone hydrogel lenses have an oxygen permeability five times higher than that of regular contact lenses, effectively improving eye health and promoting healthy lens wear.

In addition, silicone hydrogel lenses have a low water content, which means they are less likely to cause dryness in the eyes. They combine low water content with high oxygen permeability, making them comfortable to wear for extended periods.

Another benefit is their high moisture retention. Even with prolonged wear, silicone hydrogel lenses do not cause dryness. The high oxygen permeability and moisture retention properties of silicone hydrogel lenses make them an excellent choice for long-term lens wear.


However, there are some drawbacks to consider. Due to the addition of silicone, these lenses can be slightly firmer and may require some time to get used to. Silicone hydrogel lenses are also considered high-end products, which means they may be more expensive compared to other types of lenses.

When comparing silicone hydrogel and non-ionic materials, the choice depends on individual needs. Non-ionic materials are suitable for individuals with sensitive eyes, as they are thin and soft, reducing the risk of protein deposits and increasing the lifespan of the lenses. On the other hand, silicone hydrogel lenses are suitable for individuals with dry eyes, as they offer better moisture retention due to the inclusion of silicone. However, they can be slightly firmer. It’s important to note that people with healthy eyes may find regular lens materials sufficient.

In conclusion, silicone hydrogel contact lenses are a good choice for individuals with dry eyes, while non-ionic materials may be more suitable for those with sensitive eyes. It is recommended to consult with an eye care professional to determine the best lens material for your specific needs.
