Perhaps you don’t give computer eye strain much thought, but once it starts to bother you, it’s difficult to ignore. More than ever, eye protection from smartphones and computer screens is necessary, but prevention rather than treatment is the key to successfully addressing the issue.

In this article, we’ll look at a few easy preventative measures that can shield eyes from computer screens and smartphone screens.

Does using screens impair your vision?

Due to the fact that almost everyone uses a screen on a daily basis, digital eye strain (DES) is more common than ever.
While most people use smartphones, not everyone spends their entire day staring at a computer screen. According to experts, DES is present in about 50% of computer users. So, do screens impair your vision? The good news is that eye strain does not persist over time.
Although there is no proof that strain worsens your eyesight over time, it does cause excruciating discomfort and make getting through a workday challenging.

Eye Strain from Computer

What specifically does the screen do to the eyes? There are several warning signs, and depending on whether you use a computer or a smartphone, they change slightly. Let’s examine some of these symptoms and discuss how to prevent them.

Computer Eye Strain Symptoms

According to the American Optometric Association, headaches, blurred vision, dry eyes, and in severe cases, neck and shoulder pain are the most typical symptoms of eye strain. Your eyes communicate a problem to the rest of your body when they become tired.
While reading on screens, we unconsciously stop blinking, which leads to dry eyes, and other pain reactions are brought on by the body alerting us to a problem. These symptoms will appear if you stare at a screen for a long period of time, such as when you use a computer all day for work.

Let’s look at screen eye protection strategies.

How To Keep Your Eyes Safe While Using a Computer?

Use The 20/20/20 Rule

Your eyes were not made to be fixed on something in front of you all day. During long workdays, the 20/20/20 rule allows you to give your eyes the much-needed break.

If you stare at the screen for 20 minutes, you must take a 20-second break to look at something at least 20 feet away. However, the more time you spend looking away from your screen, the better.

Ensure Good Lighting in Your Space

Even though it might seem counterintuitive, less light in your workspace is actually better for your eyes when using a computer. Close your curtains and use less fluorescent lighting in the office so that it isn’t too bright.

Make sure your ambient lighting is about half as bright as the average office and use lower voltage bulbs.

Regularly have eye exams

Regular eye exams help you monitor your eye health and make sure that your issues don’t go beyond common eye strain. Additionally, it presents a wonderful chance for you to discuss your habits and eye health with a professional!

Minimize glare

Because it prevents your eyes from responding as quickly as they should to the information you’re trying to focus on, glare on your computer screen can strain your eyes.

As much as possible, use a matte anti-glare screen (rather than glass-covered LCDs). Make sure your glasses lenses have an anti-reflective coating if you wear them.

Use screens with high resolution

Most people are no longer required to use CRT screens. Those were the old computer monitors with slow refresh rates that produced a glaring flicker and hurt your eyes.

Refresh rates on screens today are typically 75Hz or higher. The better, the higher. Additionally, screens with higher resolutions seem more realistic. Your eyes don’t have to work as hard to interpret the images in front of you when you can’t see the pixels.

Limit Blue Light

Short wavelength blue light is well known for harming the eyes. Use special eyewear to cut back on blue light, or lower the screen’s color temperature. It’s perfect for ongoing use.

Smartphone Eye Strain

Mobile phone screens have the potential to strain the eyes just like computers do. We all need to have this conversation because we use them almost exclusively in place of pen and paper. But what impact do phones have on your eyes?

Symptoms of Eye Strain from a Phone

The symptoms of eye strain from a phone are very similar to those of computer eye strain. Mobile phone eye strain can result in blurred vision, dry eyes, throbbing pains around the eyes, and dry eyes. But unlike computers, we use phones differently. We could stare at a computer screen for hours on end.

We use our smartphones for brief intervals throughout the day, which adds up to hours of use. This is better for the eyes, but if you’re squinting while using the phone, it could mean that you experience these symptoms all day long without realizing that mobile phone eye strain is to blame.

Let’s look at some strategies for shielding eyes from smartphone screens.

How To Protect Eyes From Phone ?

Configure the screen

Because your screen appears perfect right out of the box, it’s simple to forget that it can be customized. However, since everyone has a different set of eyes, all smartphones let you adjust the contrast, brightness, and text settings.

When at home, reduce the brightness, or enable automatic brightness settings to let your phone change its brightness based on the lighting conditions. To make reading text messages easier, increase the text size!

Maintain a Safe Distance

Between 16 and 18 inches away, you should be able to see everything on your phone’s screen. Holding your phone too closely is not recommended, but if you must, you might want to zoom in on your screen.

Employ Night Mode

Modern Apple and Android smartphones come with night mode features that make it simple to automatically lessen eye strain at night. Once enabled, your phone will automatically change the screen settings to reflect the time of day.

Don’t Forget To Blink!

It may sound silly, but when we’re using smartphones and tablets, it’s simple to forget to blink. Unconsciously, we fixate on the content to the point of staring at the device.

We maintain eye moisture and refocus our vision each time we blink. To prevent strain and dryness, do it frequently.

Use screen protectors that reduce reflections

Despite the glossy nature of smartphone screens, matte screen protectors give you an LCD-like appearance. They shield your screen and lessen glare from outside lights or the sun. They’re also reasonably priced.

Utilize synthetic tears

Artificial tears can be an efficient tool in keeping the eyes comfortably lubricated for all types of eyestrain, whether they are brought on by computers or mobile devices. There are numerous varieties of lubricating eye drops available on the market, both with and without preservatives. Before choosing the one you prefer the most, you might need to try a few.

Although it’s crucial to adjust your phone’s brightness, most smartphones can do so automatically. Your device’s ambient light sensor means that the light will change based on how much light is already present. Additionally, the night mode function lessens the negative effects blue light has on your eyes.

The ideal screen color is one that is warmer. It’s crucial to cut down on blue light since long wavelengths are healthier for you.
