Smart medical lenses represent one of the most significant innovations in modern optometry, as they transcend the traditional role of correcting refractive errors to perform diagnostic and therapeutic functions. These lenses allow the monitoring of vital ocular indicators such as intraocular pressure, glucose levels in tears, and changes in the tear film, opening new horizons in managing chronic eye diseases such as glaucoma and diabetic retinopathy.<br /><br />Over the past decade, wearable medical technologies have witnessed remarkable advancements, with smart contact lenses gaining particular prominence. The integration of nanotechnology and miniaturized biosensors within contact lenses provides a continuous, non-invasive diagnostic platform.<br />• In glaucoma management: Lenses equipped with pressure sensors enable real-time monitoring of intraocular pressure, helping prevent the progression of vision loss caused by undetected ocular hypertension.<br />• In diabetic patients: Smart lenses offer an unconventional tool for monitoring glucose levels in tears, serving as a promising alternative to repeated blood tests.<br />• In dry eye diagnosis: Lenses embedded with humidity sensors can continuously measure tear evaporation and dynamic tear film changes.<br /><br />Smart medical lenses mark a paradigm shift in optometric practice, combining corrective, diagnostic, and therapeutic roles, thereby paving the way for more personalized and effective eye care.<br />
