The Dry Eye Detector ecosystem links upstream component suppliers, midstream manufacturers and software developers, and downstream distribution and clinical adoption. Upstream, lens, photodiode, and microโoptics providers deliver the optical building blocks for sensor modules. Midstream actors assemble these parts, embed AIโdriven analysis, and obtain medical certifications. Downstream, distributors and service firms supply calibrated detectors to ophthalmology clinics, optometry practices, and hospital ophthalmic units, where clinicians incorporate results into patientโcare pathways. Value emerges from the convergence of precision optics, data analytics, and regulatory compliance, and is captured by device makers and service providers through sales, licences, and maintenance contracts.
