An eye chart, or optotype, serves as a vital tool in the realm of visual health, enabling the subjective measurement of one's visual acuity. Typically, these charts find frequent use in the hands of healthcare professionals, including optometrists, physicians, and nurses, as an integral part of their practice for screening individuals for potential vision impairments. Ophthalmologists, those dedicated physicians who specialize in the intricate domain of ocular health, also rely on eye charts. They utilize these charts to meticulously monitor the visual acuity of their patients, particularly in response to various treatment modalities like medications or surgical interventions.
