by Author

In today’s world, screen time plays a crucial role in our lives since screens are an important part of our everyday lives. From work to education to entertainment to social interaction, screens are used everywhere. You will find that the amount of time we spend on-screen, whether it is on computers, tablets, smartphones, or televisions, has increased rapidly, making people more concerned about the potential impact of prolonged screen usage. Whether you are a student, professional, or passionate gamer, it is very important to understand how screen time impacts your eyes and what can be done to maintain optimal eye health.

Using screens that emit blue light for a long time is usually dangerous for eyesight since it causes eyesight problems and makes your vision bad. As per a study, blue light is more dangerous for children as compared to adults since they absorb this light quickly. How much time you spend on screen is also an important part of maintaining your vision, since according to many surveys, screen time for different age groups varies. For children and seniors, it is usually less, and for adults, it is a little more. Here is a blog through which you will be able to understand screen time and its side effects.

Eye Problems Caused by Prolonged Screen Time

Eye Problems

When an individual uses screens for a long period of time, it leads to a lot of eye problems. Some of these problems are short-term and usually do not last for a long period of time. Whereas some problems caused by excess use of screens are permanent, serious, and need to be taken care of. Listed below are some of the eye problems caused by prolonged screen time:

  • Eye fatigue: If an individual is working for a long period on screen, then they need to focus on objects at different distances. When you constantly adjust your focus for different objects, your muscles get stressed, causing eye fatigue.
  • Dry and irritated eyes: When an individual looks at the screen for a long period of time, they constantly stare at the screen and blink their eyes very little. This can make your eyes dry, and you will feel irritated, itchy, and gritty.
  • Blurred vision: Constantly using a screen for a long time can make an individual’s eye muscles weak since they need to focus on one particular object for a long time. By doing this, it reduces the ability of an individual to function properly and causes blurry vision.
  • Loss of focus: Prolonged use of a screen without a break can disturb the focus of an individual. When you are using a screen for a long time, it becomes difficult for the eyes to focus on a particular object since screens use bright colors and constantly change displays.
  • Nearsightedness: As per studies, if an individual has increased their screen time, the chances of developing myopia also increase. Along with this, not indulging in outdoor activities can also cause nearsightedness in them.

Beyond the Eyes, It Affects Your Sleep And Overall Health

Prolonged use of screen time not only affects your vision, but it also has a lot of other side effects. There are a lot of adverse consequences of excessive screen usage, due to which an individual has to face a lot of health-related problems. The following are some of the problems, other than eye-related, that an individual can face.

  • Improper Sleep Schedule
  • Neck and Shoulder Pain
  • Headaches
  • Risk of Chronic Diseases
  • Mental Health
  • Poor Posture
  • ADHD symptoms
  • Screen Addiction
  • FOMO

Can elongated screen time make bad vision worse?

However, there is no evidence that can prove that excessive use of a screen for a long period of time can make your bad vision worse. Eyesight problems such as nearsightedness or farsightedness can worsen over time by using screens for a long time since the eyes get stressed too much, making the individual uncomfortable. Those who are facing the problem of nearsightedness and, along with that, are using screens for hours have a greater chance of increasing their nearsightedness. Children who are growing up need to be a little more careful while using screens since it can have a very bad impact on their eyes while they are still growing.

It is also referred to as high-energy visible (HEV), and it has the shortest wavelength of around 380 to 500 nanometers and the highest energy of all visible colors. You will find that an individual is always surrounded by blue lights that are harmful for the human body.
