More than 34 million Americans are wearing contact lenses today, with another 74 million people worldwide. But how many of them know the real score about the cleanliness of their contacts? If you’re a wearer, you might want to find out where your eyes stand in connection with the contacts you’re wearing right now.
According to Dr Maria Gloria Dominguez-Bello, the lead scientist from NYU Langone Medical Centre, New York City, their research “shows that putting a foreign object, such as a contact lens, on the eye is not a neutral act.”
She expounded further that “These findings should help scientists better understand the long-standing problem of why contact-lens wearers are more prone to eye infections than non-lens wearers.”
In the research, hundreds of sample swabs from the different areas involving the eyes of 9 contact lens users and 11 individuals who were not users, were taken by the researchers.
It was discovered that for both groups, the conjunctiva, or the eye surface hosted a highly diversified range of bacteria compared to the skin located directly beneath the eye.
Three times more of bacteria of the three most typical kind such as Acinetobacter, Pseudomonas, and Lactobacillus, were found and identified on the contact lens wearer’s eyeballs.
The microbial ecosystem, otherwise known as conjunctival “microbiome” of contact lens wearers were discovered to be comparable to that of the skin than that of the eye.
