What would happen if you wore someone elses contacts?

Wearing someone else's contact lenses can lead to several issues, including eye infections, irritation, and allergic reactions. Each person's lenses are customized to their specific vision needs and eye shape, so using another person's contacts may not fit properly, leading to discomfort or damage to the eye. Additionally, sharing contacts poses a risk of transferring bacteria and other pathogens, increasing the likelihood of serious eye health complications. It's essential to use only your prescribed contacts to ensure safety and proper vision correction.
