For millions of people worldwide, the difference between sight and blindness comes down to access, not possibility. CtheGood, the new eyewear initiative by KeraLink, is working to change that through a simple but radical model. According to the company, every dollar of profit from each eyewear purchase is directed toward programs that aim to prevent and treat avoidable blindness.

Founder Mark Clark, who has spent more than two decades in the eyecare field and over twenty years in nonprofit work, saw an opportunity to turn commerce into a form of care. A father of six and a living liver donor to a lifelong friend, he brings a deeply personal perspective to his leadership.

"Instead of giving our profit to name brands, expensive fashion models, or wealthy dot-com CEOs, ours goes to help those struggling with blindness," Clark says.

A Model With a Different Metric

The company states that it operates under a 100% profit donation model, with proceeds supporting the nonprofit KeraLink International. The organization's programs have supported the training of over a hundred specialists and expanded screening and treatment capacity in underserved communities.

The company doesn't rely on traditional advertising or celebrity endorsements. Instead, it channels all resources toward expanding training and diagnostic capabilities in areas that have long been underserved. The eyewear itself reflects that same principle of quality and integrity — lenses designed for computer use or outdoor glare, and a design process focused on long-term durability rather than fashion turnover.

Purchasing as Participation

Globally, 2.2 billion people live with vision impairment, and over one billion of those cases are considered preventable. Through CtheGood, everyday consumers are invited to be part of the solution, not by donating, but by participating.

Each purchase supports locally trained eyecare specialists in underserved regions, including parts of the United States. These technicians use portable, AI-assisted diagnostic tools to identify and treat early-stage eye diseases. By equipping and retaining local professionals rather than sending short-term aid workers, the initiative aims to support long-term improvements in local vision care infrastructure.

"We have seen what happens when technology meets local talent," Clark explains. "It is not about short-term aid. It is about building systems people can actually use."

The company's approach transforms a simple purchase into a direct act of participation. Customers don't just receive glasses; they contribute to expanding access to vision care for others.

Challenging the Optics of the Industry

The eyewear market is often driven by high markups, rapid trends, and lifestyle marketing. Against that backdrop, CtheGood takes a notably different path. The company rejects luxury pricing and celebrity endorsements, choosing instead to direct its resources where they matter most — into the training and equipment that expand access to vision care.

The company states that its resources are directed toward health initiatives rather than traditional advertising. This focus on efficiency and impact is rare in consumer retail and reflects the leadership of Mark Clark, who prioritizes tangible results over branding theatrics. The company's growth relies on trust and measurable progress rather than traditional marketing, proving that purpose and performance can coexist without compromise.

Beyond Transaction, Toward Transformation

For Mark Clark, the mission of CtheGood is not limited to selling eyewear. It's about proving that business can be a vehicle for tangible social change, that profitability and purpose can move in the same direction.

"What if we built systems where helping others wasn't the exception, but the expectation?" he says.

By structuring every transaction to create impact, CtheGood, by KeraLink, shows that ethical commerce doesn't have to compromise sustainability. Each purchase contributes to programs dedicated to improving vision care, giving consumers a more direct role in restoring vision around the world.

Every purchase is more than a product exchange; it's participation in a system designed to give sight, stability, and dignity back to communities that need it most.
