The US Food and Drug Administration said on Tuesday it had sent a warning letter to Amazon.com related to sale of seven unapproved eye drops on the company s e-commerce platform.
More than 2 dozen products could cause eye infections or blindness, after bacterial contamination and unsanitary conditions were found at a manufacturing facility, the agency said.
Despite claims by their makers, blue light glasses probably don t reduce eyestrain for people who spend a lot of time looking at computer screens or phones.
