Having issues with zoom fatigue and digital eye strain – don’t forget the 20-20-20 rule!
You will recall that last year I wrote how the COVID-19 pandemic has led to a marked increase in the use of digital devices with the result that there has been a dramatic upsurge in the number of people experiencing symptoms of digital eye strain (DES), such that the term ‘zoom fatigue’ has been coined to describe this phenomenon. DES is characterized by visual disturbance and/or ocular discomfort related to the use of digital devices such as smartphones, iPads, computers and laptops.

Discontinuation of Silsoft contact lenses
One of the contact lens options we use for the contact lens management of infantile aphakia is the Silsoft lens from Bausch & Lomb. Presently the Silsoft lens is the only silicone elastomer lens on the market and this lens has previously been approved by the Food and Drug Administration in the US for both daily wear and 30-day extended wear for aphakia. The main feature of the silicone elastomer material is its very high oxygen permeability.
Jillian lecturing to optometry students at the University of Melbourne
My colleague Jillian Campbell is now recognised as one of the leading contact lens practitioners in Australia. Jillian successfully manages all our challenging contact lens patients, including the aphakic babies, post-surgical cases, patients with keratoconus and those who require contact lens fitting because of ocular trauma.

Regular contact lens after-care is essential
We see many patients in our practice – especially those with keratoconus or those who have undergone corneal graft surgery – for whom contact lenses are the only means of refractive correction. Generally, these patients have an irregular corneal shape so the improvement in vision obtained with spectacles is minimal and hence they are generally dependent on rigid contact lenses (or similar) to achieve levels of vision that allow them to manage with normal activities of daily living.
Hand sanitizer associated corneal burns increasing due to COVID-19
As a result of the COVID-19 pandemic, people around the world are now practicing strict personal hygiene against infection. This includes the regular use of alcohol-based hand sanitizers. A recent paper in the Visual Journal of Emergency Medicine reported on a surge in hand sanitizer associated ocular chemical injury to the marked increase in the use of hand sanitizers over the last year.

Rigid contact lenses – the new terminology
Rigid contact lenses are available in many forms. In the past, the classification of rigid lenses was based on differences in total diameter, although the terminology was variable.

Vale Professor Barry Cole
This blog is about a great man who left us recently. It is about a great man who was without a doubt the most important and significant person in the development of optometry as a profession over the last 60 years. It is about a great man who always inspired me and undoubtedly had the biggest influence on my career.
