Computer Vision Syndrome

What is Computer Vision Syndrome (CVS)?

This is an umbrella term describing various symptoms of discomfort caused by using computers, also known as Digital Eye Strain. According to the European Eye Fatigue 2016 report, around 80% of millennials experience symptoms of CVS. It is something that affects adults and children alike with increased use of screens.

What are the symptoms?

Symptoms are commonly felt by those using a computer for more than 2 hours a day. They include headaches, burning irritable eyes, red eyes, intermittent blurring, fatigued eyes, twitching, double vision and loss of focus. Back and shoulder pain are also common. The College of Optometrists has found lockdown increased the incidence of these symptoms.

What causes these symptoms?

When using a computer, your eyes continually focus and refocus on print of differing size, contrast and distance away. This constantly uses the accommodation system and extra-ocular muscles of the eyes. Text and images made from pixels differ from printed versions. The nature of pixels where light intensity varies within it, provides
a difficult image to focus on for long. Increase in age exacerbates this, as our ability to accommodate decreases. Images relayed to the brain vary greatly as a result causing fatigue. Blinking less will also dry the eyes out.

What can help with CVS?

Adjusting the level of glare from surrounding lighting, workstation set-up, regular breaks and changing computer settings all help. Prescription glasses with specific coatings commonly give clarity and relief of symptoms.

Mrs L.McI.

I took my 7yr old to have a routine eye test and Jonathan was fantastic with him, completely put him at ease, a much friendlier and personal approach than the large chains. Have recommended Clearvue to all family and friends.

Received very good service at the Currie branch, Jonathan the Optometrist was very thorough, took time to talk me through my eye images and was very helpful and caring. Great service received and would highly recommend to anyone. My Partner and daughter are also booked in to see Jonathan so we now have a family optician for all of our eye care.

Myself my husband and my daughter all had our eyes tested at Clearvue. Jonathan was so lovely and put us all at ease. Great choice of frames. Will definitely be recommending to friends and family.

Mrs L.T.

Expert advice from Jonathon and a fantastic range of frames. Love my new prescription Ray-Bans which were ready really quickly! Will definitely be visiting again to trial contact lenses!

Mrs K.M.

Myself and my two wee boys visited today to get our eyes tested. Jay was amazing with my sons...one of my boys was very anxious after having a bad experience at another opticians. Jay was great with him, explaining everything he was going to do before he did it and putting my wee boy at ease. My other wee boy needed drops in and he made it so easy for him. Both boys need glasses and there was a great variety to choose from- they are both delighted! Brilliant service and would highly recommend.
