Some Tokyo police officers will be allowed to wear sunglasses on the job for the first time to protect their eyes from ultraviolet rays and improve vigilance in bright sunlight.

The Metropolitan Police Department announced on Aug. 5 that personnel in its Security Police division who protect dignitaries and mobile police units can don the protective eyewear. 

“We will continue our efforts to build a better working environment so that police officers can focus on their jobs and take an active role in security,” said MPD official Takahisa Ogura.

Officers in the designated departments can wear sunglasses depending on the situation, or be required to remove them in circumstances so as not to put the public ill at ease.

Eligible personnel must purchase their own eyewear and designs that grab attention or are colored will not be permitted. 

The National Police Agency issued an official notice of promoting countermeasures against the expected summer heat wave to police departments across the nation in April.

Since then, police departments in each region have been taking various measures against the blistering heat.
