Query: It makes my eye hurt

I bought this for my 5 years old because he loved the spy gears. Since it's pretty cheap, so I gave it a try! My son played a little but isn't interested in it again. I tried this spy glasses on myself & I had to look on the sides in order to see things behind me. My eyes had to focus so closely and "widely"...after wearing it for a short time, my eyes hurt!
