Can lice be seen by the human eye?

Most people can see adult lice. However, if your vision is less than great, it can be very hard to tell a lice egg from dandruff, dust, or other debris. Using magnifying glass will help, and comparing what you find to the pictures and descriptions on our identifying lice guide. It is a myth that lice are microscopic. Microscopic means that something can only been seen with a microscope.
