Document clips for computer monitors are great if you’re constantly having to type from a paper document.
By not having to bend your neck to look at the document, you’ll reduce neck strain.
You can get them as low as $8.50 on Amazon (Referral Link)
If you’re like me and only have a laptop, you can get one like this. It’s a little pricey at $20, but if I was typing from documents all day I’d totally get it.
