Risks and Symptoms of Continuous Exposure to Electronic Screens

Continuous or excessive use of electronic screens, such as computers or cell phones, carries health risks. Specifically, it could contribute to the development of some eye diseases and others associated with various organs, systems or parts of the body. In this sense, according to the bibliography consulted, some diseases or disorders are listed below, as well as the types of recommended electronic screens. to reduce these risks.

Eye Diseases

a. Computer Vision Syndrome (CVS): Prolonged concentration on the screen, lack of blinking and poor ergonomics can cause eye strain, dry eyes, headache, blurred vision, neck and shoulder pain.

b. Digital Myopia : Long periods of close focus on screens can cause difficulty seeing distant objects.

c. Eye Fatigue and Dry Eye : Prolonged exposure and reduced blinking can cause dry, itchy or sandy eyes as a result of rapid evaporation of tears and dry eye.

d. Astigmatism : Prolonged exposure to distances less than 30 cm can cause vision distortion both near and far.

Other Diseases, Disorders or Problems

a. Attention Capacity : Constant exposure to visual and auditory stimuli can cause difficulty concentrating on complex tasks.

b. Sleep Disorders : The blue light emitted by screens can affect the production of melatonin, a hormone that regulates sleep, which could cause insomnia.

c. Postural and Muscular Problems : Prolonged use of electronic devices can cause muscle tension and pain in the neck and back.

d. Skin Problems : Blue light from electronic devices can cause changes in skin cells due to oxidative stress, causing the destruction of collagen and elastin fibers, leading to loss of skin firmness. and the appearance of wrinkles.

e. Heart Problems or Diabetes : The greater the number of hours spent sitting in front of a computer, the greater the risk of suffering from diabetes or heart disease.

Prolonged Use of Screens Causes Permanent Vision Loss

There is no clinical evidence that prolonged use of electronic screens causes permanent vision loss. Dry eyes and visual fatigue, yes, but nothing in the long term.

Recommended Electronic Screens to Reduce Health Risks.

There is no specific technology as to what type of electronic screen is most recommended to minimize eye health risks. Factors such as brightness, contrast and precise color resolution, as well as the ability to maintain image quality from various angles, among others, are taken into account when choosing different types of screens. However, it will ultimately depend on individual preferences and specific needs.

LCD (Liquid Crystal Display) TFT (Thin Film Transistor) screens are display technologies used in monitors, televisions and other electronic devices and do not cause serious long-term effects on eyesight. The same is equally applicable for other more modern technologies derived from the previous ones, such as IPS (In-Plane Switching), OLED (Organic Light- Emitting Diode) and AMOLED (Active Matrix Organic Light- Emitting Diode) screens. Each one has its own characteristics and advantages.
