How Digital Screens Affect Your Vision

In today’s digital world, screens are everywhere. From smartphones and laptops to tablets and televisions, many people spend several hours a day looking at digital devices. While technology helps us stay connected and productive, prolonged screen use can place significant strain on your eyes.

At Asgarpour Optometry, we commonly see patients experiencing eye discomfort related to extended digital screen use. Understanding how screens affect your vision is an important step toward protecting your long-term eye health.


What Is Digital Eye Strain?

Digital eye strain, also known as computer vision syndrome, refers to a group of vision and eye-related problems caused by prolonged use of digital screens. Unlike reading printed text, digital screens require your eyes to work harder due to glare, contrast, brightness, and constant focusing demands.

Common symptoms of digital eye strain include eye fatigue, dryness, headaches, blurred vision, difficulty focusing, and neck or shoulder discomfort. These symptoms may worsen over time if left untreated.


How Digital Screens Impact Your Eyes

One of the most common effects of screen use is reduced blinking. When staring at a screen, people tend to blink far less often than normal. Blinking is essential for keeping the eyes lubricated, and reduced blinking can lead to dry, irritated eyes, particularly for contact lens wearers.

Digital screens also require your eyes to maintain focus at a fixed distance for long periods. This places continuous strain on the eye’s focusing muscles and can result in visual fatigue, headaches, and temporary changes in vision clarity.

Another contributing factor is blue light exposure. Screens emit blue light, which can increase glare, visual discomfort, and eye strain, especially during extended use. Blue light exposure in the evening can also interfere with sleep patterns.

Poor ergonomics can further amplify these effects. Screens positioned too high, too close, or in poorly lit environments can increase eye strain and lead to muscle tension in the neck and shoulders.


Children and Screen Use

Children are particularly susceptible to digital eye strain. They often spend long periods on screens without breaks and may not recognize or communicate visual discomfort. Excessive screen time in children has also been associated with an increased risk of nearsightedness.

Regular eye exams are important for detecting vision changes early and ensuring healthy visual development.


Tips to Reduce Digital Eye Strain

One effective way to reduce eye strain is by following the 20-20-20 rule. Every 20 minutes, take a 20-second break and look at something at least 20 feet away. This allows the eyes to relax and refocus.

Optimizing your screen setup can also help. Keep screens at arm’s length, position them slightly below eye level, and reduce glare by adjusting lighting and screen brightness.

Blinking more frequently helps maintain eye moisture. In some cases, your optometrist may recommend lubricating eye drops to relieve dryness.

Proper eyewear is also important. Computer glasses or lenses with anti-reflective coatings can reduce glare and improve visual comfort during screen use.


The Importance of Regular Eye Exams

Symptoms of digital eye strain often overlap with uncorrected vision problems. A comprehensive eye exam can determine whether your symptoms are related to screen use, dry eyes, focusing issues, or changes in your prescription.

At Asgarpour Optometry, we tailor our eye exams to your lifestyle and visual needs, including extensive screen use at work or home.
