Product Advantages and Overview
High water content above 50% can lead to lens fragility, deformation, protein deposits, and poor astigmatism correction ability.
This is because soft lenses are prone to deformation, which causes the eyes to refocus when blinking.
On the other hand, the low water content in contact lenses offers advantages such as extended lens lifespan, reduced deposit buildup, and correction of mild astigmatism.
When wearing contact lenses for an extended period, the moisture content of the lens itself can evaporate, as the lenses do not generate water but rely on a sponge-like polymer structure to absorb moisture from the eyes.
At this point, the lens absorbs tears to maintain its original water content.
Therefore, when wearing contact lenses for a long time, higher water content is more likely to cause dry eyes. If the lens water content falls below its intended level, it needs to absorb more tears.
