Paper is manufactured from pulp which is made from trees. IE wood. The use of any paper product to clean a delicate lens can cause minute scratches on the lens which can mar the surface and interfere with the visual display when viewing something on the slide. When looking through the microscope, it is hard to determine if what you're seeing is actually on the slide or a scratch on the lens.

Antonie van Leeuwenhoek used a simple microscope with a single lens that he crafted himself, often referred to as a van Leeuwenhoek microscope. Robert Hooke used a compound microscope, which includes multiple lenses to magnify the image.
To clean a microscope lens, you can use a lens cleaning solution specifically designed for optical equipment, along with lens cleaning paper that is lint-free and soft. Gently wipe the lens in a circular motion to remove any dirt or smudges, being careful not to scratch the lens. Avoid using harsh chemicals or abrasive materials that can damage the lens.
