High Water Content Contact Lenses

High water content lenses contrary to popular belief are generally not the best for dry eyes.
High water content contact lenses. These high water hydrogel lenses have unique water binding properties that allow extreme h2o lenses to retain virtually all their water content throughout the day according to the company. As a rule with conventional soft contact lenses the greater the water content the more oxygen can pass through the lens. Manufacturers have spent time and resources perfecting the use of plastics used in lenses and as a a result the water content has risen. As a general rule with conventional soft contact lenses the higher the water content of the lens the more oxygen can pass through the lens to the surface of the eye.
Low medium and high water content. With high water content lenses the moisture in the lens draws out the eye s tears making them more prone to. Mid water content up to 60 hydrogel contact lenses suitable for most users. High water content up to 90 hydrogel contact lenses for.
Hydrogel lenses are available in three general categories. Contacts with a high water content have a higher oxygen. High water content lenses are lenses with more than 50 water whereas low water content lenses have less than 50 water. High water content lenses are more likely to cause dry eye than those with low water content.
Low water content up to 45 modern silicone hydrogel contact lenses used in contacts that are intended for continual wear. Unlike other organs in the body which receive oxygen from the bloodstream your eyes get oxygen directly from contact with the air. Soft contact lenses are categorized by how much water they contain. This is very important for lens convenience and healthy eyes but high water content lenses may be more fragile so are most likely to tear with frequent handling.
This is important for lens comfort and healthy eyes but high water content lenses may be more fragile so are more likely to tear with frequent handling. Contact lenses with a lower water content dehydrate less on the eye than do lenses with a high water content so they could be better for people with dry eyes. The water content of hydrogel lenses allows oxygen to pass through which is crucial. Contact lens wearers who are more prone to dry eye syndrome will find contact lenses with a lower water content more comfortable to wear.
They have almost 100 oxygen permeability. Extreme h2o lenses are available in weekly and two week disposable designs including toric designs for astigmatism.
