The New Epidemic 

Worldwide individuals today have access to an extensive range of digital devices and applications that boost our productivity at work and enrich our lives at home. Despite all of the benefits of technology, however, we are becoming increasingly aware of the adverse effects that these technologies can have on our lives, specifically the stress on our visual systems. Prolonged use of digital devices such as computers, tablets, and mobile phones have dramatically increased the prevalence of dry eyes, eye fatigue, and other vision-related problems, often grouped under the umbrella terms “Digital Eye Strain” or “Computer Vision Syndrome.[1]

Market research by Nielsen revealed that American adults spend an average of 11 hours per day on various screens. Forty-five per cent of TV watchers frequently use two screens at once—watching TV while scrolling through their phones or tablets. According to Apple, the average iPhone user unlocks their phone 80 times a day, which, after accounting for eight hours of sleep, amounts to one unlock every 12 minutes for 16 hours a day, every day.[2] Canadian children aged 5-17 spend an average of 3.4 hours per day on screens, or 23 hours per week.[3]

The imposition of COVID-19 stay-at-home measures has led to a further uptick in the use of digital devices. Currently, users worldwide spend an average of 6.5 hours[4] on their digital devices every day.

Another factor contributing to the demand for vision-enhancing products is the growing aging population, especially in developed countries. The World Health Organization estimates that by 2050 there will be more than 2 billion people across the world aged 60 or older.[5]  Like most systems in the human body, vision deteriorates with age. Aging increases the prevalence of conditions such as presbyopia, glaucoma, dry eyes, macular degeneration, cataracts, and diabetic retinopathy. The global markets for eye health supplements[6] dry eye treatments,[7] and myopia and presbyopia treatments[8] are all expected to grow due to increased demand driven by increased screen use and the aging population.

In Canada there are currently approximately 6 million people who suffer from dry eyes,[9] 11 million with myopia,[10] 1.5 million with AMD (age-related macular degeneration),[11] 2.5 million with cataracts,[12] 400,000 with glaucoma,[13] and 500,000 with diabetic retinopathy.[14]

In the USA there are currently approximately 16.5 million people who suffer from dry eyes,[15] 38 million with myopia,[16] 11 million with AMD, 24.4 million with cataracts, 3 million with glaucoma, and 4.1 million with diabetic retinopathy.[17]

The world faces substantial challenges in terms of eye care, eye disease prevention as well as bigger structural and societal problems pointed out by the World Health Organization as "inequalities in the coverage and quality of prevention, treatment and rehabilitation services; a shortage of trained eye care service providers; and poor integration of eye care services into health systems, among others."

We aim to address this issue head on by providing education on prevention, maintenance and products specifically designed to mitigate these problems.
