Sugra Double Mirror - Retinoscope

The Sugra Double Mirror Retinoscope is a diagnostic instrument designed for the objective measurement of refractive errors in ophthalmology. It is utilized to determine conditions such as myopia, hyperopia, and astigmatism by observing the light reflex from the patient's retina. This device is particularly beneficial for assessing patients who may have difficulty providing subjective responses, including children and individuals with communication barriers.

Beyond quantifying refractive errors, the retinoscope also offers qualitative insights into various ocular pathologies, including early detection of corneal ectasia, cataracts, and retinoblastoma. Its clinical applications extend to screening for conditions like keratoconus and evaluating accommodative function. The instrument features Optic Glass for clear observation and a durable Plastic frame, making it suitable for consistent use in laboratory settings.
