Many people have vision-related challenges—low vision, difference in sight due to partially limited color vision or cataracts, short or farsightedness, lower sight due to age, and visual impairment. 50 to 60% of Japan's general population use either glasses or contact lenses. Including temporary issues, a great number of people experience difficulty in day-to-day living.
