Using Computers may harm your eyes? Treat Computer Vision Syndrome at Home

As far as we indulge in digital lives, our hands always dive for devices like smartphones, laptops, and tablets. We opt for them to make our life easier and more convenient but on the contrary, they are affecting our eyes with Computer Vision Syndrome (CVS) or Digital Eye Strain issues.

Computer Vision Syndrome

Whether it’s studying or working, we are required to work on digital screens for a long time and this is the primary cause of this eye problem. Not only prolonged screen time but also improper posture while using the systems affects our eyes and lead to eye strain.

What can cause it?

This eye problem is mainly caused by using digital screens for a longer time without regular breaks which may lead to undue strain in eyes. Other causes may be:

Causes of Computer Vision Syndrome
  • Improper Viewing Distance: when we sit at incorrect distance that forces eyes to constantly readjust focus and it leads to discomfort and strain in eyes.
  • Improper Posture: Improper posture while using digital devices, such as slouching, leaning forward, or tilting the head forward can put undue strain on neck and shoulders. I also improper chair height, placing monitor at above eyes.
  • Poor Lighting: Lack of appropriate or excessive lighting conditions can result in screen glare, leading to eye strain. Poor ambient lighting conditions also hinder our eyes from focusing properly.
  • Blue Rays: Digital screens emit blue light that can affect our natural sleep-wake cycle and lead to eye fatigue.
  • Reduced Blinking: People tend to blink less frequently while staring intently at screens, leading to dry eyes and increased discomfort.
  • Unhealthy Work Environment: Poor indoor air quality, dry air and inadequate ventilation may all contribute to eye dryness and irritation that worsens the eye conditions.
  • Pre-existing Eye Conditions: People suffering from pre-existing eye conditions such as dry eye syndrome, refractive errors or eye muscle imbalances are more prone to these syndromes. Proper management of these conditions is essential in mitigating its impact.

What are the Symptoms?

Individuals who spend significant amounts of time using digital devices may experience various symptoms associated with this eye problem. Below are the most frequently experienced signs:

What are the symptoms?
  • Eye Strain It’s due to long hours spent staring at screens, some individuals may develop eye strain. Signs include tiredness, heaviness and discomfort in their eyes - symptoms which indicate eye strain.
  • Blurred Vision Difficulties focusing on objects after extended screen viewing sessions may lead to blurred vision.
  • Your Tear Production Is Deficient A lack of tears may result in dry, itchy eyes with an unpleasant gritty sensation.
  • Headaches Repeated headaches may be the result of eye strain associated with this eye problem.
  • Neck and Shoulder Pain Tense or sore neck and shoulder muscles caused by improper posture when using digital devices can exacerbate eye discomfort and contribute to this vision problem.
  • Eye Fatigue: Overexerting our eyes through excessive screen use may leave them feeling tired, heavy, and sore; this indicates eye fatigue.
  • Increased Sensitivity to Light: Sensitivity to bright light or glare may lead to discomfort or difficulty focusing, both of which are signs of this eye problem.
  • Double Vision: Witnessing duplicate images or objects when switching focus from screen to distant locations may indicate this syndrome.
  • Concentrating is Difficult: It has long been linked with reduced ability to focus, as indicated by difficulties focusing on tasks after prolonged screen exposure.
  • Colour Distortion: Changed perception of colors, such as perceiving hues differently or experiencing fringing, could be indicative of these syndromes.

Effective Solutions to lessen the effects of computer vision syndromes

solutions to prevent CVS
  • Make sure your workstation is Ergonomic: It can be maintained with a comfortable chair height, positioning the monitor at eye level, and adjusting lighting. It can help reduce glare.
  • Implement the 20-20-20 Rule: Adopting the 20-20-20 rule, taking a 20 second break every 20 minutes by looking away at 20ft each time, helps ease eye strain significantly. This is considered as the best method to reduce eye fatigue.
  • Make an effort to blink regularly while using digital devices: We normally blink 12-15 times in a minute, but while using the screens, due to concentration it reduces to 5-7 times only. So, blinking regularly while using digital devices can help reduce dryness and vision problems, including dry eye syndrome.
  • Adjust display settings: Adjusting display settings such as brightness, contrast and font size to reduce eye strain can be helpful. The digital screens emit blue light or rays which damages our eyes, to protect it we can use anti-reflective computer glasses that may further minimize any damage from blue light exposure.
  • Implement Eye Exercise: Incorporating simple eye exercises into your daily routine is a great way to relax and strengthen eye muscles, such as palming, eye rolls and focusing exercises. Regularly scheduled eye exercises may alleviate eye strain while improving overall eye health.
  • Use Lubricating Drops: After consulting an eye specialist, we can use lubricating drops after every 2-3 hours while using the screens. This would help our eyes provide moisture and avoid dryness.

Here are the frequently asked questions (FAQs):

Q.1 Are computer vision problem permanent?

Ans: Traditionally speaking, it tends to be temporary and can usually be managed effectively with some simple lifestyle modifications and appropriate precautions.

Q.2 Can blue light glasses help prevent these syndromes?

Ans: Blue light glasses may provide relief by filtering out harmful blue light emitted by screens and protecting eyes while mitigating these symptoms.

Q.3 How can I reduce screen glare?

Ans: To effectively decrease glare on your screen, position it away from direct light sources, use anti-glare screen filters and adjust ambient lighting in your environment as these measures will significantly lessen discomfort caused by screen glare.

If you still face this then go for an eye specialist to manage and reduce the discomfort caused due to Computer Vision Syndrome. Let’s move towards a healthier lifestyle.
