To what extent is the computer to blame for your vision problems?

To what extent is the computer to blame for your vision problems?

Recently, Twitter co-founder Christopher Isaac "Biz" Stone has sent a message to those who are browsing their "social network" for hours on end: "This is not healthy. " Stone says people should visit your site, which is very popular, but should not devote their lives to it. In addition to the negative social repercussions of being always ahead of the computer screen, looking at it, Stone's statement carries more weight: our eyes can be harmed as well.

Some experts agree, but say the computer screen may not actually be the cause of the damage. Although computers do not cause known ill effects on vision, computer users often complain of tiredness of the eyes, headaches, eye fatigue and difficulty focusing. These symptoms, however, are not caused by the computer screen itself, but rather by the conditions surrounding the computer screen.

Pay attention to inappropriate lighting in the environment where the computer is located, improperly placed equipment computer and even the inappropriate choice of furniture that houses the computer, which can cause the above mentioned symptoms, after looking at the computer screen for a long time.

Muscle fatigue

Our eye muscles function as any other muscle in our body. When they become fatigued, the eyes may feel uncomfortable, pain may arise and the vision may begin to blur.

Our eye muscles work just like any other muscle in our body. When they become fatigued, their eyes may feel uncomfortable, pain may arise and their vision may begin to blur.

But if your profession requires you to look at the computer screen for much of the day, there are measures which can prevent eye irritation. Every 20 minutes of work, you should divert your gaze from the screen to an object 20 meters away for 20 seconds.

The size of the computer screen is also something very important. LCD screens can cause less eye strain than older screens. And adjusting the text size to get more visual comfort can also help.


Gallbladder stone: diet helps in controlling the problem

Gallbladder stone: diet helps in controlling the problem

Gallstones are a major public health problem affecting about 20% of the population. They are caused by a complex interaction between dietary, genetic, metabolic and environmental factors. The vast majority of stones are made up primarily of cholesterol, inside the gallbladder. This is due to a multifactorial process that involves to a varying degree the presence of a bile with excess cholesterol, reduction of substances inhibiting the formation of crystals and impaired gallbladder motility.

Fluoridated water protects adult and children's health

Fluoridated water protects adult and children's health

Chapel Hill, NC - Fluoridated water promotes protection against caries in adults , even though they have not consumed fluoridated water as children, say researchers in the US and Australia. A study published online in the Journal of Dental Research showed that adults who spent more than 75 percent of their lifetime in a community with water fluoride had 30% less dental caries compared to adults who lived more than 25% of their lifetime in communities without fluoridated water.
