Digital eye strain (DES) or visual fatigue (VF) has been recognized as a health condition for more than two decades. With increasing screen use by all ages the problem is a common one. The following discusses the most regularly seen symptoms and the efforts we can take to reduce their severity or prevent them from occurring in the first place.

The most common symptoms
According to the American Optometric Association, the following are the most commonly reported symptoms.
- Eye strain (fatigue and tired eyes)
- Blurred vision
- Dry, itchy, and irritated eyes
- Neck and shoulder pain
The most common causes
The two biggest enemies to eye health are blue light and glare. Today’s computer, laptop, tablet, and phone screens all emit blue light. This, combined with the glare they also produce, has a detrimental effect on our vision. There’s also increasing evidence that overexposure to blue light causes damage to the retina, one of the structures within the eye.The very act of focusing on a screen for extended periods causes excess stress on the eyes. It puts further strain on the ciliary muscle at the back of the eye, causing it to spasm. This can be a key cause of ocular migraine, blurred vision, and eye fatigue.Add in the fact that concentrating on a screen-related task means we forget to blink regularly, reducing the natural eye lubrication, and you can understand where the dryness, itching, and irritated symptoms come from.The penchant for hunching over devices or poor posture when working at a desk is what leads to neck and shoulder pain.
How to Alleviate Digital Eye Strain
- Glasses and lenses
- Eye drops

Glasses and lenses
Using computer glasses that eliminate glare and filter blue light is one of the best ways to help reduce the effects of digital eye strain. There are many on the market but are of varying quality. The best incorporate lenses that eliminate glare and filter blue light and can, if you need them, have a magnification element.For most people, the glasses are those that utilize the prescription from your ophthalmologist and are fashioned specifically for when you’re working at your computer or looking at a device.
Because we tend to blink less when looking at a screen, those who suffer from dry, irritated eyes might benefit from using eye drops (also called artificial tears).
The 20-20-20 rule
This means that every 20 minutes you should look away from your screen and stare at something around 20 feet away for at least 20 seconds. This will help reduce the stress your eyes undergo when looking at a screen for extended periods.Make it even healthier by standing and walking around for a minute or so. That will also go some way to helping alleviate posture-related pain in your neck, shoulders, and back.
It’s vitally important that your work station is set up so you’re at the proper distance from your screen and positioned at the right height. This helps prevent squinting and ensures you’re not hunching over as you work. This will go a long way to helping with musculoskeletal pain in your neck and shoulders.
