Treat Computer Vision Syndrome with us

Computer Vision Syndrome (CVS) or Digital Eye Strain is widely spreading in this digital world. Daily we use our smartphones and computer screens for the entertainment, job, etc. However, it’s affecting our eyes, if we continually see screens without breaks and precautions. Prolonged screen time is the primary cause of this digital eye strain.

Computer Vision Syndrome Treatment

What can cause digital eye strain?

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

  • Incorrect viewing distance forces constant focus readjustment.
  • Slouching or improper posture causes strain on neck and shoulders.
  • Poor lighting leads to screen glare and difficulty focusing.
  • Blue light from screens disrupts sleep patterns and tires the eyes.
  • Reduced blinking causes dry eyes and discomfort.
  • Unhealthy indoor environment worsens eye dryness and irritation.
  • Pre-existing eye conditions increase susceptibility to strain.

What are the symptoms of digital eye strain?

Anyone who spends most of the time in digital screens can be affected with this eye problem. However the most frequently experienced signs:

What are the symptoms?
  • Eye Strain: Tired, heavy eyes from prolonged screen use.
  • Blurred Vision: Difficulty focusing after screen time.
  • Dry Eyes: Itchy, gritty sensation due to insufficient tears.
  • Headaches: Recurring headaches linked to eye strain.
  • Neck and Shoulder Pain: Discomfort from poor posture exacerbating eye issues.
  • Eye Fatigue: Eyes feeling tired and sore from excessive screen time.
  • Light Sensitivity: Discomfort or focus difficulty in bright light.
  • Double Vision: Seeing duplicate images when shifting focus.
  • Difficulty Concentrating: Struggle to focus after screen exposure.
  • Color Distortion: Altered perception of hues or fringing.

Effective Treatments for computer vision syndrome

solutions to prevent CVS
  • How you sit and work matters a lot. You must choose a comfortable chair height, position the monitor below the eye level, also adjust display and room lightning.
  • 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.
  • We normally blink 12-15 times in a minute, but while using the screens, due to concentration we reduce it to 5-7 times only. So, blinking regularly while using digital devices can help reduce dryness and vision problems, including dry eye syndrome.
  • The digital screens emit blue light or rays which damages your eyes, to protect it you can use anti-reflective computer glasses that may further minimize any damage from blue light exposure. Even if your vision is 6/6, wear a blue cut glasses while using the computer.
  • Implementing simple eye exercises into your daily routine is a great way to relax and strengthen eye muscles; palming, eye rolls and focusing exercises can help.
  • After consulting an eye specialist, you can use lubricating drops after every 2-3 hours while using the screens. This would help your eyes provide moisture and avoid dryness.

Changes in Eyeglasses Prescription

Nearly 71 percent of those reporting symptoms of Computer Vision Syndrome also use eyeglasses or contact lenses, and report more eye, neck, and back discomfort than people without optical aids. These results demonstrate the need to make improvements in how people utilize and wear their optical aids.

Tips for Eyeglass wearers

Eyeglass wearers must ensure their glasses fit properly; otherwise, their optical center shifts, leading to blurred vision and eyestrain as well as neck strain from tilting the head back. To prevent this, adjust frames or seek professional fitting. Bifocal, trifocal and progressive lens users face additional challenges as these prescriptions make it harder to see directly ahead or at arm's length, which worsen computer-related eye strain. Adjusting lens height or power, or purchasing special computer glasses can help alleviate symptoms.

Tips for Contact Lens wearers

Contact lens wearers must remember to blink when working at their computers, as computer use reduces blinking rates to one third of normal, while looking straight ahead at screens exposes more of the eyeball to air, leading to rapid drying out and irritation if contact lenses rest on corneas. If frequent blinking alone doesn't suffice in eliminating symptoms, ophthalmologists can prescribe eye drops specifically formulated for contact lenses to ease symptoms of dryness or itching.

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. Let’s move towards a healthier lifestyle.
