Verified By Dr. Mukesh Jha | 04-Apr-2026

Dr. Mukesh Jha, Consultant Psychiatrist at Kailash Hospital, Noida, and Dr. Kunal Singh, Consultant Ophthalmologist at Kailash Hospital, Noida, regularly meet many patients through different lenses one treats a restless, anxious mind, while the other takes care of dry, strained eyes. And the message they deliver is unambiguous excessive phone use is slowly poisoning an entire generation. Most patients ask, "What is the amount of screen time that will do no harm?" And the response to this is, as both the specialists would put it, a very subjective matter.

Today, we wake up to the feeling that we are holding something in our hands, rather than touching a hand of our beloved or sipping some refreshing water it is our smartphone, the glowing cold glass of screen.

According to predictions, by 2026, on average, one spends seven hours or more watching the screen in big cities like Delhi NCR. Work, fun, communication, or entertainment you have your reason for scrolling and swiping endlessly in front of the mobile phone screen. So when your time spent in front of the phone exceeds some limit, you start asking yourself a crucial question what is the right amount of phone screen time, and how much harm it can cause?

What is Considered Healthy Screen Time?

The definition of healthy screen time use has undergone change since then. While experts recommended a fixed ceiling of two hours in the early 2010s, the same does not seem practicable in 2026 for a modern-day professional.

There are no definitive numbers when it comes to a safe number of screen hours. While the American Academy of Paediatrics recommends certain numbers for children, adults have a more complex scenario to deal with. Adults need to consider their activity, timing, and emotions while using screens.

The primary distinction is between active screen time use and passive screen time use:

• Active Screen Time: Engaging in video calls with family members, learning new skills, producing content, or working with productivity apps. This type of screen time use is productive and harmless.
• Passive Screen Time Use: Browsing social media feed mindlessly, watching videos suggested by algorithms, or playing unproductive games. This is generally associated with negative results.

A reasonable benchmark for an adult is to aim for less than 2 hours of recreational, passive screen time per day outside of work or essential tasks. Total screen time (including work) often exceeds 10-12 hours, making the non-negotiable breaks and boundaries even more critical.

Effects of Excessive Screen Time

Psychiatric Perspective: The Impact of Screen Time on Mental Well-being

As explained by Dr. Mukesh Jha, the repercussions of excessive use of screens on mental well-being are severe and complex.

Dopamine Loop and Addictiveness:

Each notification, like, or new update generates the production of some amount of dopamine, known as the feel-good neurotransmitter. It acts as an intermittent reinforcement and establishes a powerful reward loop, making people addicted to their phones, similar to the gambling addiction mechanism.

Increased Cases of Anxiety and Depression:

From several scientific investigations, it can be observed that there is a clear relationship between prolonged use of screens and rising cases of anxiety and depression. Social comparison fear, FOMO, and exposure to negative news content are just some of the many reasons behind this trend. In one study, it was found that restricting social media usage to half an hour per day reduces depression and feelings of loneliness.

"This is because the person who suffers from the side effects of high screen time tends to feel helpless," according to Dr. Jha. "He or she feels the effect of his or her phone but is unable to control the scrolling and is hence helpless and feels trapped. Helplessness or a lack of control is common in people with behavioral addictions and drives the side effects."

Sleep Disturbance:

"Using your phone before bedtime can affect melatonin levels," says Dr. Jha. "As a result, your body may experience difficulty in falling asleep because using your phone at bedtime will reduce slow-wave sleep and increase light sleep." In addition, blue light has been shown to have an adverse effect on the sleep-wake cycle by reducing REM sleep, causing sleep problems, which may be associated with mental health issues.

Poor Attention Span:

Social media sites such as Instagram Reels and TikTok encourage frequent and fast-changing information input. As a result, your brain gets used to the speed and novelty offered by these sites, which causes poor attention span.

The Ophthalmologic Perspective: Your Eyes on Screens

According to Dr. Kunal Singh, prolonged exposure to screens is increasingly affecting the visual health of people, including younger individuals.

Computer Vision Syndrome/Digital Eye Strain:

The most frequently encountered problem is computer vision syndrome. The following symptoms may appear:

• Dry, red, or irritated eyes
• Double vision and blurriness
• Frontal or temple headaches
• Pain in the neck and shoulders (caused by incorrect posture while operating a device)

Dry Eye Syndrome:

While concentrating on a screen, we blink less often – the rate drops by up to 60%. Tears are released during each blink, covering the eye surface and maintaining proper hydration. Fewer blinks lead to faster evaporation of tears and, consequently, dry eyes, which can be both painful and harmful to the cornea. 

Progressive Myopia (Nearsightedness):

Sustained use of electronic devices has been linked to an increased incidence of myopia, which is especially pronounced in developing children. Sustained use and lack of outdoor activities have shown to be one of the major causes for this phenomenon.

"I am seeing kids at age eight who have problems with their eyes that are symptomatic of dry eyes and eyestrain issues," notes Dr. Singh. "It is very worrying what the impact of too much screen time has on developing vision in kids. We are probably looking at an epidemic of myopia soon."

How to Balance Your Digital Life?

Promoting your health in the digital age does not necessitate a total rejection of smartphones; rather, it requires an intentional and balanced approach to their use. You just need a strategy. Dr. Kunal Singh and Dr. Mukesh Jha recommend the following protocol for anyone visiting Kailash Hospital, Noida:

• The 20-20-20 Rule for Eyes: To give your eyes a break, try looking at something 20 feet away for at least 20 seconds every 20 minutes. Dr. Kunal Singh points out, "This allows the ciliary muscles in the eye to relax." It's one of the easiest ways to reduce the impact of long hours in front of a screen.
• The "Digital Sunset": Switch off all screens at least 60 minutes before bed. Use this time for "analog" activities like journaling, stretching, or light conversation.
• Grey-Scale Mode: One of the best ways to combat high screen time effects on the brain is to turn your phone to grey-scale. "The brain is attracted to bright, vibrant colors," notes Dr. Mukesh Jha. "When the screen is grey, it becomes a boring tool rather than an addictive toy. This is a game-changer for avoiding burnout at work and reducing mobile screen time."
• Optimize Your Ergonomics: Hold your phone at eye level. Looking down at your lap creates up to 60 lbs of pressure on your neck, contributing to the side effects of excessive screen time known as "text neck."
