Step-by-step explanation:
Contact lenses are not suggested in the lab because they can introduce another surface into the natural anatomy of the eye, potentially impacting the normal microbiota and contributing to eye diseases.
Additionally, chemicals and fumes in the lab may react with contact lenses, causing damage to the eye. If contact lenses are worn, precautions should be taken such as wearing appropriate protective eyewear over them to prevent chemical contact.
In terms of safety precautions, when working in the lab, you should carry a compound optical microscope carefully and know the correct procedure when using powerful optical lenses.
