The Growing Burden of Myopia—and Why Multifocal Vision Isn’t Always Enough

Myopia (nearsightedness) is no longer a minor inconvenience—it’s a global health trend reshaping how we see the world. Today, more than 2.6 billion people are affected, and projections suggest that by 2050, half of the global population could be myopic, according to research highlighted by the Vision Center. In highly urbanized regions, prevalence rates among young adults already reach 80–90%, according to findings reported by Stanford Medicine.

At its core, myopia occurs when the eye elongates, causing light to focus in front of the retina rather than directly on it. While glasses and contact lenses can correct this, they don’t address the underlying progression—and for many people, vision needs don’t stay static.

When Myopia Meets Aging

As myopic individuals age, a new challenge often emerges: presbyopia. This age-related condition reduces the eye’s ability to focus on near objects, typically starting around age 40. Globally, presbyopia affects nearly 1.8 billion people, impacting productivity and quality of life, according to the British Contact Lens Association.

For someone with myopia, this creates a paradox. They may rely on correction to see far distances clearly, but suddenly struggle with near vision while wearing those same lenses. The result? Constant switching between glasses, removing contacts to read, or compromising clarity at one distance to function at another.

Consider Daniel, a 45-year-old architect. For decades, his myopia was easily managed with contact lenses. But as presbyopia set in, he found himself juggling between distance correction for site visits and reading glasses for blueprints. “I feel like I’m always choosing what I want to see clearly,” he explains.

The Multifocal Compromise

Multifocal lenses were introduced to bridge this gap—offering simultaneous correction for near, intermediate, and distance vision. Adoption has grown significantly, with multifocal and monovision lenses now accounting for over 60% of presbyopia-related contact lens fittings, according to research from the University of Manchester.

Yet, for many users, these solutions come with trade-offs.

Multifocal designs rely on splitting incoming light into multiple focal points. While this enables vision at different distances, it can also reduce contrast sensitivity and create visual disturbances such as halos or glare—particularly in low-light environments. In real life, this might mean difficulty reading a menu in a dim restaurant or noticing reduced sharpness while driving at night.

Take Sarah, a marketing executive who spends her day switching between screens and meetings. After transitioning to multifocal lenses, she noticed that while her near vision improved, “everything feels slightly less crisp, especially by the end of the day.”

These compromises highlight a fundamental limitation: static optical designs attempt to serve dynamic visual needs.

Toward a More Responsive Future

Human vision is inherently adaptive. Our eyes constantly adjust focus depending on where we look—whether it’s a phone screen, a laptop, or a distant horizon. Traditional corrective lenses, however, remain fixed in their optical properties.

This mismatch between dynamic visual behavior and static correction is where emerging technologies begin to show promise. Imagine lenses that adjust in real time, responding to where and how you’re looking—restoring clarity without compromise.

As the global burden of myopia and presbyopia continues to rise, the demand isn’t just for correction—it’s for solutions that align with how we actually live, work, and see.
