Biotrue ONEday is the latest in cutting-edge technology from the eye care professionals at Bausch and Lomb. Designed to mimic the human eye鈥檚 natural surface this is a daily contact lens that provides outstanding all day comfort. Made from hypergel, the latest advanced contact lens material, the lens holds exactly 78% water. This is roughly the same amount of water that the human cornea holds, allowing for a much more natural fit to your eye. In fact, because Biotrue ONEday lenses are designed to retain that moisture thoughout the day, it will feel as natural as if you weren鈥檛 wearing any lenses at all. The unique design of Biotrue ONEday has proven itself to be outstanding, even when up against the leading daily disposables on the market. In a recent study by Bausch and Lomb it retained the highest levels of moisture and the best shape after 16 hours of wear. High definition optics ensure you can always see clearly by reducing halos and glare, especially in bright sunshine or low-light. This is combined with a special UV filter to block out harmful levels of sunlight. However, Biotrue ONEday is not a substitute for a good pair of sunglasses. Biotrue ONEday has been created to reflect human biology and therefore offers an outstanding lens wearing experience suitable for any contact lens wearer who needs correction for long or short-sightedness, partnered with the freedom of a daily wearing pattern.
