Eight batches of sunglasses from luxury brands such as Christian Dior, Michael Kors, Ferragamo and Burberry were found to be substandard, Shanghai’s market watchdog said.

Burberry sunglasses sold at Grand Gateway 66 in Xuhui District failed for visible light transmittance, the Shanghai Administration for Market Regulation said yesterday.

The real visible light transmittance of three batches of sunglasses failed to live up to their labels, it added.

Michael Kors sunglasses sold at the ifc Mall and a batch of H&M sunglasses hadthe same problem, it said.The H&M sunglasses also failed for corrosion resistance against sweat.

Such sunglasses will fade and peel, leaking heavy metals such as nickel and lead, probably causing skin problems, it said.

A batch of Christian Dior and Ferragamo sunglasses each failed for labeling that lacked types, categories or standards of the products, which will affect consumers’ choice and proper use of sunglasses.

A total of 40 batches of sunglasses were tested.
