Overview
It is an unusually very common problem with many people’s eyes, usually resulting from hereditary or environmental causes. However, a new type of astigmatism has been recognized with the increased usage of computers, and that is why it is known as computer-caused astigmatism. This article will explain how long exposure to a computer leads to astigmatism, its signs, and remedies that one can put into action to overcome the problem.
What is Computer-Caused Astigmatism?
It occurs when either the cornea or lens of the eye has an irregular shape which causes the light failing to focus straight on the retina thereby an image seen is hazy or distorted. Astigmatism caused by a computer is the worsening of symptoms that follows more screen exposure over time. There has been greater exposure than ever before with the context of remote working, attending classes online, and viewing movies and TV programs from different corners of the globe through smart devices.
How Does Computer Use Cause Astigmatism?
The computer does not actually “cause” astigmatism in the real sense but may worsen already existing conditions or show symptoms similar to astigmatism. Here is how:
Digital Eye Strain: The use of computers for a long period requires much effort from the eyes, and it may be strained and uncomfortable.
Essential Viewing Distance: When viewed at a distance close or far from the screen, it blurs the natural focusing ability of the eyes, thereby worsening the condition of astigmatism.
Blue Light Exposure: High energy from the screens in the form of blue light causes fatigue in the eyes and indirectly worsens the condition of astigmatism.
Low Blink Rate: The person tends to blink less while concentrating on screens, thereby causing dry eyes and increased visual strain.
The Role of Poor Posture and Lighting
Direct eye strain is not the only significant role played by poor ergonomics in developing computer-caused astigmatism. Working at the wrong angle or in dim lighting will increase the workload on your eyes, which may further distort the vision.
Symptoms of Computer-Caused Astigmatism
Equally, identifying the symptoms of computer-induced astigmatism is essential so that interventions take place promptly. A few of the most common symptoms are:
- Blurry or distorted vision
- Discomfort in eyes
- Recurring headaches
- Struggling to focus on words or pictures
- Increasing sensitivity to light
- Watery or dry eyes
If you have any of these symptoms, particularly when you spend too much time on your screens, observe your usage and seek out an eye doctor.
Prevention and Remedies
Fortunately, there are so many ways to prevent and minimize the effects of computer-induced astigmatism. You can easily reduce its impact through healthy screen habits and ergonomic adjustments.
1. Observe the 20-20-20 Rule
The simplest way to reduce digital eye strain is by following the 20-20-20 rule: every 20 minutes look at something 20 feet away for 20 seconds. This simple habit allows your eyes to relax and recover from constant focus on the screen.
2. Change Screen Settings
Adjusting your screen settings can be quite a difference. Ensure:
- The brightness matches the surrounding environment.
- The font sizes are large enough to read without straining.
- Exposure is reduced by using blue light filters or glasses.
3. Maintain Proper Ergonomics
A well-designed workspace can help prevent computer-caused astigmatism. Key adjustments include:
| Ergonomic Adjustment | Recommendation |
| Screen Position | Keep it 20-30 inches from your eyes. |
| Screen Height | Align the top of the screen with eye level. |
| Chair Support | Use a chair with proper lumbar support. |
| Desk Lighting | Use ambient light to avoid glare. |
4. Break Periodically from the Computer
Break time from the computer can decrease eye strain and boost productivity at large. Breaking every hour can reduce the symptoms of computer-induced astigmatism.
5. Hydrate and Blink Frequently
Hydration of the eyes is important. Drink enough water throughout the day, and consciously try to blink.
6. Consult an Eye Specialist
If symptoms do not alleviate, go see an optometrist or ophthalmologist. They may prescribe:
- Prescription glasses with anti-reflective coating.
- Eye exercises prescribed according to your condition.
- Artificial tears for teariness.
Long Term Complications
Ignoring computer caused astigmatism will develop more severe complications. For instance, chronic strain will exacerbate the current level of astigmatism and even trigger myopia conditions. Furthermore, chronic pain affects your productivity and living quality.
Conclusion
Computer-induced astigmatism is a condition which is growing rapidly and for which active measures have to be taken against it. With knowledge of what causes computer-induced astigmatism, being aware of the symptoms, and cultivating preventive habits, you can protect your eye health in this digitally-driven world. Take action today and reduce the impact of prolonged screen use on your vision.
FAQs on Computer-Caused Astigmatism
1. Does computer usage affect my eyes permanently?
Computer cannot really be faulted for permanent damage of eyes. However, long exposures could worsen pre-existing astigmatism and may eventually develop chronic symptoms.
2. How do I distinguish between computer-induced astigmatism and normal astigmatism?
Computer-induced astigmatism usually worsens following prolonged screen exposure, whereas it improves with correct breaks and ergonomic adjustments.
3. Do blue light glasses work?
Yes, blue light glasses filter out the harmful blue light and reduces eye strain. It thus becomes a useful tool in the prevention of computer-caused astigmatism.
4. How often should I get my eyes checked?
Getting regular eye exams is very important. Frequent computer users must visit an eye specialist once a year.
5. Can children develop computer-caused astigmatism?
Indeed, children are also vulnerable to it with increased online learning. You have to keep track of their screen time and ergonomics as well.
