The Contact Lens Society of Japan has conducted relevant investigations in particular on the current state of manufacture and wearing of cosmetic contact lenses. In the three months from July to September last year, there were at least 395 incidents of eye injuries caused by improper wearing of cosmetic contact lenses. Among the more than 300 incidents, women accounted for 97.7%, and 86.5% of all incidents occurred in young people aged 15 to 29. The main symptom is inflammation of the cornea or conjunctiva. According to the statistics of the Japanese Academy of Ophthalmology, cosmetic lenses account for the vast majority of eye diseases caused by contact lenses. The main eye diseases caused are corneal ulcers and corneal infiltration. The patterns or colors on cosmetic lenses currently on the market are mainly divided into these three types: printing and coloring on the inside or outside of the lens, and sandwiching the colored material between two transparent lenses. Coloring on the inner side of the lens can easily cause damage to the cornea, and coloring on the outer side of the lens can easily cause conjunctival lesions. The lens with the colored material in the middle is relatively safe, but the manufacturing process is still a trade secret. Therefore, it is the first step to prevent the damage caused by improper wearing of the lenses.
