Diseases such as cataracts that affect the front of the eye (also called the anterior segment) are among the leading causes of visual impairment worldwide. Losing your vision reduces independence, mobility, and overall quality of life. Unfortunately, many people are not screened until vision loss symptoms become more severe—and in some cases, irreversible.

“It is in a patient’s best interests to undergo regular check-ups, but this isn’t always easy,” explains Nakazawa. “The instruments needed to conduct these exams are expensive, bulky, and largely confined to clinical settings. Patients in rural areas or with low mobility may not be able to access these vital screening tools—leaving them in the dark.”
