The Effects of Screen Time on Dry Eye Syndrome

The increasing use of digital devices has led to the prevalence of dry eye syndrome. Excessive screen use can lead to symptoms such as eyestrain, dryness, headaches, and irritation. Digital eyestrain (DES) is a common problem among individuals of all ages. Children are spending more time indoors using digital devices, leading to an increase in myopia. 

 

Reduced Blinking
 

Studies show people blink less often when using computers and other digital devices. They often blink five times per minute, compared to 10 to 12 times when performing other activities. Blinking helps spread tears across the eye surface. Tears are vital for keeping the eyes healthy and moist. When you fail to blink frequently, the eyes become dry and irritated.   

 

Lack of Hydration
 

Health specialists recommend people drink two to three liters of water each day. Staying hydrated is beneficial not just for physical health but also for eye health. Drinking water will keep the eyes well hydrated, preventing dry eye symptoms. Unfortunately, most people fail to consume adequate water when gaming or working on the computer, exacerbating dry eye symptoms. 

 

Dry Eye and Blurry Vision
 

Blurry vision is a prevalent symptom of dry eye syndrome. When tears fail to coat the eye surface adequately, it affects the cornea. A dry and rough cornea surface affects visual clarity and comfort. 
 

People with dry eye syndrome find it difficult to wear standard contact lenses due to eye dryness. Eye doctors recommend specialized contact lenses to reduce dry eye symptoms. Scleral rigid gas-permeable lenses provide hydration while improving visual acuity.

 

Treatment for Dry Eye Syndrome
 

If your dry eye condition is due to prolonged screen use, the eye doctor can recommend ways to reduce the discomfort. Nonprescription lubricating eye drops can help reduce mild or moderate dry eye symptoms. 
 

Using the drops regularly throughout the day can help soothe the eyes by keeping them hydrated. If the drops fail to provide relief, the doctor can recommend other treatment options. A diagnosis can determine if the condition is due to meibomian gland dysfunction or blepharitis. 
 

How to Avoid Dry Eye Due to DES

 

There are things you can do to reduce dry eye symptoms due to digital screen use. They include: 
 

  • Resting your eyes while using the screen can help reduce dryness. Follow the 20-20-20 rule and look at an object 20 feet away for 20 seconds every 20 minutes. 

  • Remember to blink frequently when using your screen

  • Use artificial tears occasionally when using your computer to keep your eyes moist

  • Use a humidifier to add moisture to indoor air

  • Adjust your computer screen to prevent glare, and place it at arm’s length

  • Take plenty of water to stay well hydrated

  • Avoid smoking and consume a healthy diet


If your dry eye symptoms persist, visit an eye specialist for diagnosis and treatment. A comprehensive eye exam can determine the underlying cause of your condition. The best treatment considers the individual’s lifestyle, eye condition, and underlying health issues. Dry eye due to increased screen time is usually reversible. Studies show that reducing digital device use or changing habits can reduce symptoms.
