Or get this nice thingie instead of new glasses. Note that the name of the link doesn't match the product (USB microscope) so I hope it stays valid. At most shops you pay almost double the price of this one. I bought it last week and it works nice. The main disadvantage is the stand which limits the size of the object you can get in the image/video.
Note that the depth of field ("scherptediepte") is very small, so you need to adjust the focus very precisely or you will get a blurry picture. As an example a recording of my RN2483-pictail board.
