A Danish startup says your next eye exam could happen through your phone.
Copenhagen-based OptikosPrime claims it can generate a full vision prescription using nothing more than a standard smartphone camera. Unlike apps that simply screen for blurry vision, its Argus prototype moves into true refraction, the precise measurement required to prescribe corrective lenses. The company reports a mean absolute error of 0.51 diopters and is aiming for the 0.25 diopter clinical standard used in professional prescriptions. If independently validated, that would put a mobile phone within striking distance of high-end optometry equipment.
The bigger story is access.
Clinical machines depend on controlled lighting, chin rests, and steady positioning. Smartphones operate in chaos. Yet OptikosPrime says it engineered around those variables to deliver results in under 60 seconds. That could matter enormously in rural settings and developing countries, where bulky $5,000 to $20,000 machines are often impractical. With the World Health Organization estimating that 2.2 billion people live with vision impairment, and at least 1 billion cases remain unaddressed, the opportunity is massive.
The company is working with Sightsavers to refine the tool using real-world data from Africa and Asia, and collaborating with Karolinska Institute for clinical validation.
If the technology holds up, it could remove one of the biggest bottlenecks in both online eyewear sales and global eye care delivery: getting an accurate prescription in the first place.
