Silicone hydrogel stands out in the contact lens world for many reasons. It is now one of the most commonly used contact lens materials. You may be wearing silicone hydrogel lenses right now! This blog post will explore its many features and benefits.
1. Unprecedented Oxygen Permeability
Silicone hydrogel contact lenses are known for their excellent oxygen flow. The role of oxygen permeability in eye health cannot be overstated. By allowing the eyes to 'breathe,' silicone hydrogel lenses enable longer wear times with reduced discomfort, making them ideal for those with active lifestyles or for those who prefer extended-wear lenses. This remarkable level of oxygen transmission supports natural tear production, ensuring that the eyes remain hydrated and comfortable throughout the day.
2. Superior Moisture Retention for Lasting Comfort
Beyond oxygen permeability, silicone hydrogel lenses boast superior moisture retention capabilities. This feature is critical for contact lens wearers, as maintaining optimal moisture ensures all-day comfort. The material's structure is designed to mimic the eye's natural moisture conditions, providing a cushion of hydration that reduces the need for rewetting drops and enhances wearer comfort.
3. Enhanced Lens Surface Technology for Eye Health
Silicone hydrogel lenses are not just about the material but also cutting-edge surface technologies that enhance their performance and benefits. Manufacturers employ various treatments and coatings to reduce the accumulation of deposits and pathogens on the lens surface, promoting a healthier eye surface and reducing the risk of infection. Innovations such as plasma surface modification improve wettability and lubricity, ensuring the lenses remain comfortable to wear throughout use.
Another aspect of enhanced lens technology is the development of lenses that effectively block harmful UV rays.
Not all silicone hydrogel lenses have added UV protection. Check the lens information with your eye doctor to ensure your lenses have this feature. *
While not a substitute for protective eyewear, these lenses add an extra layer of defense against the potential damage caused by prolonged exposure to UV radiation. Combined with the silicone hydrogel material's superior moisture retention and high oxygen permeability, these advanced lens technologies offer an unrivaled level of protection and comfort for the modern contact lens wearer.
