Do I need my family to sign the three-sided mirror?

There is no need for family members to sign, and the three-sided mirror is to check the fundus, so there is no risk. You don't have to be signed by your family, but you should be accompanied when you do the examination, because your eyes will be anesthetized locally before the examination, and your eyes will feel uncomfortable after the examination, which will lead to blurred vision and easy safety accidents, so it is best to be accompanied by someone to do the three-sided mirror.

Knowledge expansion:

The refractive index of corneal tissue is examined by three-sided mirror, which can shorten the anesthesia time and eliminate retinal rupture. However, if the cornea is stimulated, it will lead to corneal epithelial damage and affect vision. If corneal tissue is damaged, eye drops or ointment should be used in time, and hot towels should be used. It is suggested that if you have eye problems, you should go to a regular hospital for examination in time and pay attention to eye health.

I hope my answer can help you and wish you health!
