Why Eyes Feel Heavy And Tired All The Time? Eye Fatigue Explained
Why do your eyes feel heavy and tired all the time? This feeling has been named differently by science, such as eye fatigue and eye strain. When you have it, you consistently experience ocular fatigue and feel exhausted, which affects your work, focus, and also reduces productivity.
Various factors contribute to eye fatigue. Like, reading on screen, bright or dim light, blinking eyes less frequently, and overuse of the eyes without a break.
The good news is, you don’t need to worry about it as it’s not a serious concern. Just by making changes to your environment, routine, and workspace, you can get rid of the eyestrain. We’ll teach you how to do that in this article.
Main Causes That Your Eyes Feel Heavy And Tired All The Time
The eyes feel heavy and tired all the time, usually because of the bright or dim lighting, prolonged screen time, reading on screens, writing, driving, and many other reasons.

Bright or Dim Lighting
Excessively bright or dim lighting both are harmful to your eyes. The bright lights strain the eyes by making them work hard, while the dim lighting forces the eyes to adjust constantly, leading to tiredness and heaviness.
Prolonged Screen Time
If you spend hours sitting in front of your computers or using your phones or consoles, it can cause eye strain. This type of eye strain is also called computer vision syndrome. It’s the reason for approximately 10 million annual eye doctor visits.
Reading
Reading on a screen requires constant focus, and that puts pressure on your eyes. The tiny fonts and the glare of the screen make it worse, leading to weary eyes, blurred vision and headaches.
Writing
Writing requires long periods of close-up focus, and eye muscles stay tense without resting. That causes heaviness and difficulty refocusing at distances. When you write on a computer, that’s even worse, as the glare is also added to it.
Driving
Driving shifts your eye focus between the road, the mirror and the dashboard. The bright headlights or the dim conditions add extra strain to your eyes. When you drive for a long time and also don’t blink, it leads to dryness in the eyes.
Small Text On Digital Devices
If you’re used to reading text messages on devices with too small fonts, then your eyes need to strain more to see them. If you do so for a long time, it leads to eye fatigue.
Reduced Blinking
Normally, a person blinks 18 times per minute, which refreshes the eyes. Due to screens, the blinking has dropped by half, causing dryness, itchiness, burning and weary eyes.
Symptoms Of Eye Strain
These are the common symptoms of eye strain.

- Blurred or double sight
- Eye soreness or irritation
- Trouble keeping focus
- Light sensitivity increases
- Eyes feel dry or watery
- Neck, back, or shoulder pain
