New Contact Lens Update Addresses Top Pandemic-Related Eye Issues

WATERLOO, Ontario, December 13, 2021—The Centre for Ocular Research & Education (CORE) has published Issue 63 of Contact Lens Update, which explores the COVID-19 pandemic’s impact on five clinically relevant ocular conditions. The latest edition and all past issues are available for free at

Highly pertinent for eye care practitioners worldwide, the issue examines and summarizes how mask wear, home schooling, and remote working may impact patients presenting to clinical practice—and potential prevention and mitigation approaches.

Lyndon Jones

CORE Director Lyndon Jones’ opening editorial provides a thorough review of five possible pandemic-related ocular complications. These cover a potential increase in myopia and dry eye complaints linked to increased digital device use, along with a discussion around whether mask wearing has increased rates of hordeolum and chalazion, dry eye, and dissatisfaction with spectacle wear. The article includes several clinical pearls to help practitioners investigate and manage these conditions.

Rosa Yang

In the feature article, CORE’s Rosa Yang discusses key findings from a paper investigating the progression of myopia in a large sample of school-aged children after COVID-19 home confinement in China. As remote education continues, the findings should interest any practitioners who examine young children and are employing or considering myopia management.

The final two contributed pieces discuss the impact of mask wear on the ocular surface and on spectacles fogging. Carole Maldonado-Codina, associate director of Eurolens Research at the University of Manchester, is the author of a recent poster that investigates patient preference between spectacles and contact lenses while wearing a mask.

Keyur Patel, clinical director at Tompkins Knight & Son Optometrists in the U.K., presents a compelling case study looking at the impact of inappropriate mask-wear on the break-up time of tears over the ocular surface. He then provides highly relevant and timely advice on how this can result in increased symptoms of dry eye that patients may not even vaguely link to their mask use.

“Almost exactly two years after the first reports of a deadly respiratory illness started to emerge out of China, the pandemic continues to dominate our daily lives,” said Dr. Jones. “These changes include children being educated at home, adults working remotely, an increase in digital device use, and mask wearing and social distancing become widespread globally.

“How do these factors impact our eyes? Modifications to our daily lives appear to have a much greater impact than we could have imagined. Contact Lens Update has consolidated and examined the most pronounced changes in detail using an evidence-based approach to provide practitioners with sound, timely clinical advice on how to look for and manage related complications.”
