Good Morning Dr. Attia, I'm an optometrist in a multi-doc/multi-location Optometry Office. All practices were private practices, but now are owned by Private Equity. In AZ, patients are resistant to wearing masks and frankly when doing an ophthalmological exam, masks really fog up our instruments. As one of the founding Docs of the new company, I have some input to clinical decisions. Can you please point me to research on Mask efficacy? Our staff will likely remain masked, but my hope is to allow patients to choose if they wish to wear a mask or not. THANK YOU
