Water content articles are a significant feature in soft disposable lenses. Generally, the larger the water content with the lens, the greater oxygen can move across its surface.This can help with comfort levels plus maintains optimum eye health. But that high water content lenses are now and again more fragile, so may tear with frequent handling. However, if you have silicone hydrogel lenses, water submissions are probably be a lesser concern. This is because their bond between water content and oxygen permeation of these lenses is different, and silicon hydrogel can continue to transmit high numbers of oxygen inspite of water percentage.
Hard contacts
Hard lenses – or rigid gas permeable (RPG) lenses – are manufactured from durable plastic and they enable the efficient transfer of oxygen to the eye. Due to their rigidity, they could often offer sharper improvements to vision than soft lenses.
