s a higher water content better for contact lenses? The water content refers to the proportion of water in the lens material. A higher water content improves oxygen permeability and makes the lens softer, resulting in greater comfort. However, when the water content exceeds 50%, lenses can become more prone to damage and deformation, and are more likely to attract protein deposits and dirt, which can negatively affect astigmatism correction. Therefore, high water content lenses are generally suitable for short-term use, with daily and weekly lenses typically having more than 58% water content.

Additionally, high water content lenses are not ideal for long-term wear, as they tend to absorb moisture from the eyes to maintain their water content, leading to dryness. People with dry eyes should avoid wearing high water content lenses for extended periods. For longer wear, it is recommended to choose lenses with lower water content, around 38-42%. Ultimately, the choice of contact lenses should be based on your individual needs.
