Most users have a typical level of vision impairment and dexterity but find that the green light gives them the alignment they need to insert the lens quickly without stress or experiencing the occasional misaligned and painful insertion.

● Used by those with steady hands and who can accomplish the lid spread with one hand.
● Focus on light prevents flinching of the eye and guarantees proper centering of the lens to prevent misaligned insertions.
● Helpful training tool for doctors and technicians. Reduces anxiety for first time insertions. Green light gives a positive psychological message. Green light means it’s safe to go.
● Helpful to any patient.
● We are told by many customers that they can insert the lens with their fingers or a standard plunger, but that they use this because they can insert their lens with more confidence and get out the door faster in the morning. Others say it prevents the occasional misaligned insertion which can be painful.
● Some clinics and practices dispense more of these than the See-Green System with stand.

At See-Green®, we often say we’re in the clarity business. But clarity doesn’t just come from our green light, it comes from the people behind it. Our small, dedicated team at Dalsey Adaptives works every day to make scleral lens insertion easier, safer, and more empowering for patients.

The Spark: Inventor & Founder
John Dalsey
Every idea starts with a problem. For John, that problem appeared nearly 20 years ago while helping a friend with mobility challenges insert a scleral lens. His question: “What if there was a way to show the eye exactly where to go?”
That question became the See-Green light-guided inserter, developed in collaboration with BostonSight® clinicians. Today, John still oversees every stage of product development, from prototyping improvements to final assembly, always guided by real patient needs.
The Steady Hand: Lead Technician
Sherry Gemme
Every great innovation needs someone who can bring it to life with precision and heart. For Sherry, that’s been her calling since she joined See-Green in 2018. What began as a role quickly became a passion: she often says it’s “the best job ever.”
Her commitment became especially clear during the COVID-19 pandemic, when her unwavering dedication kept operations moving day after day. Today, Sherry continues to ensure every product meets the highest standard, bringing skill, consistency, and genuine care to everything she touches.
