CONTACT LENSES
Wearing contact lenses in a histopathology laboratory constitutes a hazard. Chemicals, bacterial and viral aerosols can dissolve in tears and become trapped under contact lenses. This can cause a variety of eye disorders of which conjunctivitis is the most common.43
Some corrosive chemicals can damage the surface of contact lenses as well as the eye. Wearing spectacles rather than contact lenses not only eliminates this hazard but also provides a barrier to aerosols, splashes and flying glass chips (produced when a diamond pencil is used to label glass slides).
