What can I do to protect my eyes during at home ipl?

Hello, I got an at home ipl machine for hair removal but it did not come with glasses. The manufacturer just says to look away and close your eyes. I found some glasses online but they are very expensive. How else can I protect my eyes? I want to use it on my legs and belly so nowhere near my face. If I have my legs under a desk but my face over it as I am sitting in the chair will that provide protection? Thank you
