The health of our eyes is often overlooked, despite the fact that our eyes are subjected to enormous stress every day. Whether it's hours spent in front of a computer screen, prolonged reading, or daily activities like driving, the eyes are constantly at work. This can lead to a common but often underestimated problem: eye strain, also known as "visual fatigue." As an optician, I see many people who endure annoying symptoms like headaches, tired eyes, and blurred vision, without realizing that proper correction could easily resolve these issues and significantly improve their quality of life.
What is visual fatigue and why is it so common?
Visual fatigue is an increasingly common condition, especially with the rise in the use of digital devices. The screens of computers, smartphones, and tablets emit blue light, which can cause eye strain when viewed for long periods. However, everyday activities such as reading, driving, or working in poorly lit environments can also contribute to eye strain. Some common symptoms include:
- Frequent headaches, especially after reading or working on the computer for extended periods.
- Dry eyes or excessive tearing.
- Blurred or double vision.
- Burning sensation, itching, or fatigue in the eyes.
- Difficulty concentrating or feeling generally tired.
Many people ignore these symptoms, considering them a normal part of modern life, but the reality is that they should not be accepted as inevitable.
The Risks of Ignoring Visual Fatigue
Not addressing visual fatigue not only means living with discomfort and annoying symptoms, but it can also lead to more serious problems. Here’s what can happen if these signals are ignored:
- Deterioration of Vision: Eyes that are constantly under stress can become fatigued more quickly and cause vision problems over time, worsening existing conditions such as myopia or astigmatism.
- Headaches and Stress: Visual fatigue is one of the main causes of headaches and can also contribute to increased stress and general fatigue. This negatively impacts the quality of life and productivity.
- Reduced Sleep Quality: Prolonged exposure to blue light from screens can disrupt the body's natural circadian rhythm, reducing sleep quality and causing a range of negative health effects.
- Posture Problems: When the eyes are tired or unable to focus properly, we tend to shift into uncomfortable positions or push our heads forward, causing tension in the neck and shoulders.
How proper correction can reduce eye strain
Many of the symptoms of eye strain can be reduced or eliminated with a simple, proper vision correction. Here’s how:
- Prescription Glasses or Customized Contact Lenses: A regular eye exam can identify refractive errors such as nearsightedness, farsightedness, astigmatism, or presbyopia that may be causing discomfort. Once corrected, these issues can drastically reduce the need to strain the eyes.
- Blue Light Filter Lenses: For those who spend many hours in front of a screen, using glasses with a blue light filter can significantly reduce eye strain and improve comfort, especially during long work or study sessions.
- Ergonomic and Lighting Tips: An optician can provide personalized advice on the ergonomics of the workstation and lighting, which can make a significant difference in reducing eye strain.
- 20-20-20 Rule: During eye exams, we can teach simple habits like the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet (about 6 meters) away. This helps reduce eye strain.
Benefits of Optimal Visual Comfort
A correct and comfortable vision goes beyond simply improving visual sharpness. An adequate correction can:
- Increasing Productivity and Well-Being: Working or studying without visual discomfort improves concentration and efficiency.
- Reduce Headaches and Symptoms of Fatigue: Clear vision means less strain on the eyes, less tension, and fewer headaches.
- Improving Sleep Quality: By reducing exposure to blue light and alleviating eye strain, it is possible to improve sleep quality.
- Improving Quality of Life: With comfortable vision, all daily activities – from reading to work, to driving and recreational activities – become more enjoyable.
