Is a higher water content in contact lenses always better?

Many customers asked us: Isn’t a higher water content better for moisture?The water content in contact lenses is undoubtedly one of the indicators when choosing lenses, but it’s more important to understand your needs and lifestyle habits!

What is Water Content (隱形眼鏡含水量)?

1. The water content of a contact lens refers to the proportion of moisture in the lens. For example, if a lens has a water content of 38%, it means that 38% of the lens is made up of water. Water content is categorized into low, medium, and high levels. 訂隱形眼鏡

• Low Water Content (0–38%)
• Medium Water Content (39–60%)
• High Water Content (60% and above)

Is higher water content always better?

• While moisture helps deliver oxygen to the lenses, higher water content does not necessarily mean better moisture retention. Lenses with high water content lose moisture more quickly and may absorb tears in eyes to maintain hydration, which can exacerbate dryness for those with dry eyes.
