In today's digital age, the use of electronic devices such as cell phones, computers, and tablets has become a part of everyday life. From work and study to entertainment, almost every activity involves a digital screen. However, without realizing it, this habit can impact eye health if not balanced with proper usage patterns.
The Impact of Digital Screen Use on the Eyes
Staring at a screen for long periods of time can cause various conditions known as Digital Eye Strain or Computer Vision Syndrome . Some common symptoms include:
- Tired and heavy eyes
- Dry or watery eyes
- Blurred vision or difficulty focusing
- Headache
- Pain in the neck and shoulders
This complaint can be experienced by anyone, including adults, teenagers, and children, especially with the increasing use of gadgets for online work and learning.
Why Do Your Eyes Get Tired Easily When Staring at a Screen?
When staring at a digital screen, a person's blink rate tends to decrease by up to 50%. As a result, eyes become dry and tired more quickly. Furthermore, exposure to blue light from screens can increase eye strain, especially if used for extended periods without a break.
An unergonomic screen position, suboptimal room lighting, and the use of inappropriate glasses can also worsen eye conditions.
Tips for Maintaining Eye Health in the Digital Age
Here are some simple but effective steps to maintain eye health:
1. Apply the 20-20-20 Rule
Every 20 minutes of staring at a screen, look away at an object 20 feet (±6 meters) away for 20 seconds to reduce eye strain.
2. Pay attention to position and lighting
Make sure the screen is level with or slightly below eye level, at a distance of about 50–70 cm. Use adequate room lighting and avoid direct glare on the screen.
3. Blink Consciously
Get into the habit of blinking more often to keep the surface of your eyes moist and prevent dry eyes.
4. Limit Children's Use of Gadgets
Excessive gadget use in children can increase the risk of refractive disorders such as nearsightedness (myopia). Parents are advised to regulate screen time and encourage outdoor activities.
5. Have Regular Eye Exams
Regular eye examinations are important, especially for individuals who work in front of a screen for more than 6 hours per day.
Consult an eye doctor immediately if the following symptoms do not improve even after reducing screen use:
- Eyes feel sore or painful
- Persistent blurred vision
- Persistent red eyes
- Frequent headaches after using screens
An ophthalmologist will perform a thorough examination to determine the cause of the complaint and provide appropriate therapy, ranging from administering eye drops, corrective eyeglasses, to educating about healthier visual habits.
