Requesting help from others. Received these three questions from a fourth grade class. They are preforming a science project.
1) Who invented the first pair of eyeglasses?
2) What are the nosepieces made out of?
3) What other materials do you use?
The second question is the tough one. I am not sure of the different material used in nose pads.
Please remember that these are fourth graders so we will want to simplify the answers.
Thank you in advance for your assistance.
