Silicone Hydrogel Contact Lenses: The Future of Vision
The Future of Vision
Advancements in soft contact lens technology have been revolutionized by silicone hydrogel lenses. These lenses allow wearers the convenience of sleeping in them safely, a long-awaited development. After extensive research and testing, affordable and safe continuous wear lenses are now available. Let's explore what makes silicone hydrogel lenses exceptional and why they might be the perfect choice for you.
Why Silicone Hydrogel?
The idea of silicone hydrogel lenses emerged over 20 years ago, presenting a blend of challenges and potential benefits. Researchers invested heavily to achieve today's high-performance lenses, viewing this material as the future standard in eye care.
Currently, you can find silicone hydrogel lenses in the US from leading manufacturers such as CIBA Vision’s “Night & Day” and "O2OPTIX," Bausch & Lomb’s "Pure Vision," and J&J Vision Care’s "Acuvue OASYS" and "Advance."
Oxygen Transmission
Silicone hydrogel lenses excel primarily due to their superior oxygen permeability. This is crucial for maintaining eye health. The key indicator, known as the "Dk" index, measures oxygen transmission, and higher numbers mean better oxygen flow.
Traditional hydrogel lenses rely on water content for oxygen permeability, maxing out at a Dk of 80. However, silicone hydrogel lenses invert this relationship, increasing Dk with higher silicone content, resulting in significantly better oxygen transmission.
Sleeping in Your Lenses
Research indicates a strong preference among lens wearers for overnight wear. According to CIBA Vision data, 84% of users occasionally sleep in their lenses, and 72% would prefer doing so if it were safe. Silicone hydrogel lenses meet this demand with high oxygen permeability, making them ideal for overnight use.
Easy Handling
Due to their silicone content, these lenses are more rigid, which can be a benefit. They are easier to handle, making them suitable for users with less delicate touch. However, this rigidity may reduce initial comfort, as they don’t conform as easily to the eye's shape.
Reduced Deposits
Traditional contact lenses often suffer from protein and lipid buildup, which is linked to wear duration and material. Fortunately, silicone hydrogel lenses significantly reduce protein and lysozyme deposition, especially with proper care and replacement schedules.
Combatting Dry Eyes
Many traditional lens wearers experience discomfort and dryness towards the end of the day. Research shows that after using silicone hydrogel lenses for a week, the percentage of wearers experiencing end-of-day dryness dropped dramatically to 13%.
Lifestyle Benefits
The unique properties of silicone hydrogel lenses offer lifestyle advantages. Continuous wear lenses are perfect for professionals with long, unpredictable hours, such as healthcare workers, police, military personnel, and firefighters. They also benefit active individuals who enjoy outdoor activities like camping and hiking, where lens maintenance can be challenging.
The Future is Clear
Given their numerous advantages over traditional lenses, silicone hydrogel lenses are poised to become the preferred choice for daily and overnight wear. They offer improved performance, excellent handling, and increased comfort. As these lenses set a new standard, they may soon become the go-to option for everyday use.
