Study: Glasses-wearers up to three times less likely to get COVID

The researchers found participants touched their face up to 23 times each hour on average and their eyes an average of three times per hour.

They found the risk of contracting Covid-19 was two to three times lower among those who wear glasses.

“Touching and rubbing of the eyes with contaminated hands may be a significant route of infection,” the report said.

“Long term use of spectacles may prevent repeated touching and rubbing of the eyes.”
