How To Protect Your Eyes From Harmful Blue Light When You Spend A Lot Of Time In Front Of Your Computer

Femme4 talks about how gadgets affect vision and whether it is really possible to keep a fresh look at work in front of a blue screen.


The eyes are comfortable looking into the distance – this is the physiological state of the rest of the visual system, which arose as a result of its evolution. They are used to focusing on objects near the eye only for a short time. However, smartphones and laptops have changed the situation – today, about half of the waking time, our gaze is directed to objects located near and at medium distances. Long-term work at such a distance without special eye protection can provoke visual fatigue syndrome, the expert says.

In addition, by sticking to the screens of smartphones, blue light additionally burdens the eyes and harms the eyes. It is the portion of visible light with the shortest wavelength and highest damaging energy, which causes discomfort and visual impairment.

Symptoms of blurred vision:

  • A veil periodically appears before the eyes;
  • The picture blurred or doubled, especially when looking at distant objects at the end of the working day;
  • There is dryness, burning and redness of the eyes;
  • Frequent headaches, pain in the eyebrows and / or soreness when moving the eyeballs;
  • A person gets tired quickly with any visual load.


1. Pay attention to the organization of the workspace:

Make sure that the distance from the eyes to the monitor is at least 35-40 cm;

reduce screen brightness if possible.

 2. If your eyes feel dry, use moisturizing eye drops without preservatives.

Looking at the blue screen of the gadget, we do not notice that we begin to blink less often. Due to insufficient hydration of the surface of the eye, you may feel a burning sensation and stinging, which impair performance and quality of life in general. Today, special drops help to eliminate these symptoms, which increase lacrimation, moisturize the mucous membrane and return a comfortable look.

3. Remember to take breaks.

The eyes need rest and recovery not only at night. To maintain a clear view, it is very important to take breaks from work at the computer or phone: go outside, breathe fresh air. In the room, adhere to the 20/20/20 rule: every 20 minutes in front of the screen, move your gaze, look into the distance for 20 seconds, blinking more often.

4. Use glasses with blue radiation protection

Experts say that glasses to protect against harmful blue light can be used all the time. They increase visual comfort while working with gadgets and reduce the risk of developing visual fatigue syndrome.

Even if you follow all the rules listed above, do not forget to visit your ophthalmologist at least once a year. Preventive examinations make it possible to identify violations and pathologies of vision at an early stage and timely help the eyes, which today are experiencing a huge load, adds an expert.
