My specs fell apart, so I ordered two new pairs from Ebay for a fiver, with free postage. The estimated arrival date was between this Saturday to next Saturday. To my surprise, they arrived today by Royal Mail next day delivery. Thinking Wow, that must have caused them more than they are worth? Then after rinsing them due to previous issues with chemicals making my eyes sting, it still happened after wearing them. So I washed them again, this time in warm soapy water, and they seem much better.
