Computer Vision Syndrome: Symptoms, Treatment, the COVID-19 Pandemic and More

A recent study conducted by Eyesafe Nielson revealed after March of 2020, the average American’s screentime increased by approximately 60%. Amidst the COVID-19 pandemic, youth are spending prolonged hours in front of computer, phone and television screens. The result are vision-related problems―known as Computer Vision Syndrome (CVS). 

Common CVS Symptoms

Most of these symptoms are short-term and will disappear with breaks from screentime. However, if extreme screen times persist, these symptoms may worsen:

• Dry or red eyes

• Aching neck and shoulders

• Blurred vision 

• Frequent headaches

• Eyestrains

• Eye fatigue

• Double vision

Common CVS Causes 

CVS can be caused by:

• Digital screen glare

• Poor seating posture (slouching)

• Seating too close to screens 

• Already-present vision problems (farsightedness, astigmatism, presbyopia)

• Poor lighting

• Prolonged screentime

CVS Prevention

Through various preventive measures, CVS can be avoided. 

• More blinking: Lack of blinking while utilizing screens is often contributes to getting CVS. Blinking more keeps the eye moist and prevents dry eyes. 

• Rest eyes frequently: To prevent eyestrain, follow the 20-20-20 rule: look at an object 20 feet away for 20 seconds every 20 minutes. 

• Sit properly: Have good posture and position the computer screen slightly below eye level and approximately 25 inches away. 

• Using an anti-glare screen: Consider the amount of exposure to blue light your eyes receive. Use a screen glare filter to decrease the amount of light reflected off the screen and into your eyes.
