Are You Spending More Time in Front of Screens?
If you feel that you spend too much time staring at digital screens, especially your phone and laptop, then you’re not alone. Between work and leisure, most people are now spending more hours than ever in front of computers and other digital devices. In this digital age, our exposure to screens has increased dramatically, affecting people of all ages.
Optometrists are increasingly concerned that excessive screen time could be affecting our eye health, causing digital eye strain (DES), also known as computer vision syndrome.
Understanding Blue Light and How It Affects Your Eyes
Most digital devices and computer screens emit unnaturally high levels of blue light. This type of visible light has shorter wavelengths that carry more energy than other light sources. Blue light exposure can negatively impact your eye health in various ways, and understanding how blue light affects your vision is essential for long-term eye health.
Symptoms of Digital Eye Strain
Digital eyestrain can manifest through several uncomfortable symptoms:
-
Reduced blinking, which leads to dry eyes as tears evaporate
-
Squinting, which can affect vision quality and cause eye fatigue
-
Blurred vision after extended periods of computer work
-
Eye discomfort and general eye fatigue
-
Shoulder pain due to poor posture at your workstation
-
Headaches caused by eye muscles working harder to focus
Blue light has also been linked to eye surface toxicity and infections. Excessive blue light and too much exposure to bright light can strain your eye muscles, making it difficult for your eyes to focus properly.
Long-Term Effects of Blue Light Exposure
There is evidence to suggest that long-term exposure to blue light could increase your risk of developing diseases of the retina, including macular degeneration or atrophy of the retina. When blue light passes through the eye, it can potentially damage sensitive cells over prolonged periods.
How to Reduce Eye Strain and Protect Your Vision
Managing your screen time and taking proactive steps can help reduce eye strain and maintain comfortable vision. Here are effective strategies to protect your eyes:
Take Regular Breaks
Give your eye muscles time to relax by stepping away from your computer screen and other digital devices throughout the day.
Follow the 20/20/20 Rule
Every 20 minutes, spend 20 seconds looking at something about 20 feet (6 metres) away. This allows your eyes to focus on long distances and gives them a break from intense use. Set a timer if you’re worried you may forget.
Adjust Your Screen Settings
Reduce glare and adjust the brightness settings on your screens to match the ambient light in your environment. Poor lighting and poor contrast can worsen eye strain symptoms, so ensure your workstation has adequate light sources without creating harsh glare on your computer monitors.
Optimise Your Workstation
Position your screen at eye level and adjust your setup to improve your posture. This can help prevent shoulder pain and reduce strain during extended use of digital devices.
Practice Healthy Blinking Habits
Close or rest your eyes when not reading, and practice regular deep blinking to promote eye hydration. Reduced blinking is one of the most common causes of dry eyes when using screens.
Use Lubricating Eye Drops
Artificial tears and eye drops can help combat dryness caused by reduced blinking during long periods of screen time. Keep them nearby for relief throughout the day.
Schedule an Eye Exam
Have regular eye tests and ask your optometrist for personalised advice. An eye exam can detect uncorrected vision problems and refractive errors that may be contributing to your symptoms. Your optometrist can also check for eye muscle imbalance and recommend appropriate solutions.
Invest in Blue Light Filter Lenses
Blue light control lenses and glasses with a blue light filter can help reduce the amount of blue light that reaches your eyes. These specialised lenses are designed for people who spend long periods in front of screens and can make a significant difference in reducing eye strain symptoms.
Consider Contact Lenses Options
If you prefer contact lenses, speak with your optometrist about options that can help with digital eye strain. Some modern lenses are designed specifically for people who use computers and other digital screens extensively.
Seek Professional Advice for Dry Eye Symptoms
If you experience persistent dry eyes, consult your optometrist. They may recommend specific treatments or eye exercises to improve your eye health.
Protecting Children’s Eyes in the Digital Age
Today’s young people love their screens, as any parent will tell you. Younger eyes are actually at greatest risk, as they still have very clear lenses which filter out very few light rays from the sun and artificial light sources like light bulbs and screens.
Unlike some adults, modern kids have literally grown up with screens, watching TV and using cell phones and other digital devices daily. This means that over the course of their lifetimes, their eyes could potentially receive decades of extra blue light exposure. While not enough research has been done in this area, there are reasons to be concerned about this cumulative effect on vision and overall eye health.
Parents should monitor their children’s screen time and ensure they take regular breaks. Wearing glasses with blue light protection and practising eye exercises can help protect young eyes during extended periods of digital device use.
