What is the primary reason to avoid wearing contact lenses in the lab?

The primary reason to avoid wearing contact lenses in the lab is that they can trap chemicals against the eye. This can lead to serious eye irritation or damage if hazardous substances come into contact with the lenses. In the event of a chemical splash or exposure, the contact lenses can hold the irritant close to the surface of the eye, increasing the risk of injury and making it difficult to flush the chemicals out effectively.

Wearing safety goggles is essential to protect the eyes from potential hazards, and they do not pose the same risks as contact lenses. Proper eye protection is critical in a laboratory setting to ensure safety and prevent chemical exposure to sensitive areas like the eyes.
