Eyelash extensions, popular among Japanese women, are increasingly responsible for eye problems.
From January to June, the police detected four cases in which eyelash extension services were offered without a required license authorizing beauticians to put the extensions on their clients' own eyelashes. The figure equals the total number for 2010 and 2011.
The four cases were found in Saitama, Chiba, Kyoto and Hyogo prefectures, according to the National Police Agency.
Officials of the National Consumer Affairs Center and other sources said consultations on health problems related to eyelash extensions started to become noticeable around 2007 in line with an increase in the number of salons offering such services. Since 2009, the number of consultations on related problems, including eye pain, persistent congestion of the eyes, eyesight deterioration and cornea damage, has totaled around 90 a year.
A Tokyo woman in her 30s went to a hospital by ambulance after feeling eye pain on the day she got extensions. Damage to the whole cornea was found.
