Why is it important to pay attention to this problem?
People began to see worse. According to the study of the famous British Okulist David Allambi, the number of shorters increased by 35% compared with 1997, when the smartphones were not and in risen, and mobile phones were just beginning to be in use. If the progression continues, then by 2035, more than half of people around the world (55%) will have weak vision.
Thanks to Allambi and its experiments, there was even a special term - screen myopia.
Is the vision really spoil?
Results of these Research of British scientists can be believed - confirm the experts of the Russian Institute of RAMS. The report says that reading from a small screen Yes even in an uncomfortable posture and with poor lighting Sits of vision at times faster than, let's say, reading a paper book at home in bed.
"Under the blow" is mainly those used by the users, which, with the help of gadgets, cast trips to the subway, train, route taxis. Vibration, change of illuminated and dark sections of the tunnel, shaking wagons - all this prevents the look and makes it less often blinking. In addition to impairment, the use of devices in transport can cause headaches and even nausea.
Are smartphones as harmful as computers?
No, smartphones and 7-inch tablets are much more damaging to the eyes than computers. Of course, the reason lies in the diagonal of the screen. To see what is written on the tiny display of a smartphone, you have to bring the device too close to the eyes, and this negatively affects the concentration of vision and contributes to the destruction of the macula - part of the eye, which allows a person to distinguish fine details.
Are all phones equally harmful?
Renowned ophthalmologist Andrew Hepford warns that violet and blue shades cause the most damage to the eyes. From this point of view, it is worth "fearing" first of all displays AMOLED, which are known for the uneven brightness of colors and the predominance of purple.
AMOLED displays have been installed on Samsung devices for a long time, and their acidity (excessively intense, unbelievable brightness) has become the talk of the town. It is clear that this characteristic also affects the eyes not in the best way.
How to use a gadget so as not to impair your eyesight?
There are many recommendations about this, but the main thing to watch out for is the distance from the smartphone to the eyes. A curious experiment organized by the American " Journal of Optometry and Vision Science" (" Journal of Optometry and Vision Science") showed that out of 129 participants in the experiment, none of them kept the gadget at the required distance. People bring mobile devices to their faces, on average, 4-6 cm closer than allowed.
How far should you keep your smartphone?
In the publication of the same " Magazine" the rule " 1 - 2 - 10"is set out, which everyone who wants to stay with good eyesight. The rule is : smartphone screen must be placed 1 foot (30 cm) from the face, computer monitor - 2 feet (60 cm), TV blue screen - 10 feet (3 m).
Exercise "20-20-20" - what is it about?
“ 20-20-20 ” is a well-known exercise recommended by ophthalmologists and allows you not to overload your eyes when working with a smartphone or computer. Every 20 minutes of operation, take your eyes off the monitor and focus for 20 seconds on a point approximately 6 meters (20 feet) away. This will be enough time for the eyes to get a well-deserved rest.
Is it possible to adjust the phone so that the eyesight does not go down?
By adjusting the gadget's settings, you can reduce the negative impact on vision. First of all, you should set a font large enough so that the text on the screen is clearly visible from a distance of 30 cm. Android smartphones have fonts like “ Large ” and “ Huge". On the iPhone, the size of the letters is controlled by the slider, which can be found in the “ Text Size ” section in the main settings.
Also it is worth adjusting the brightness. You need to proceed from how well the room is lit. Remember: when you had to look at an overly bright display in the dark, you felt physical pain. That's a lot of stress on the eyes! iPhone owners are advised to use the “ Auto-brightness ” option (in the “ Wallpaper and brightness ” section of settings) - it automatically adjusts the display brightness to external conditions and copes with it with a bang.
It will not be possible to set up the gadget so that the vision does not shrink at all - for this you will have to completely abandon the use of mobile devices.
Is it possible to save vision thanks to mobile accessories?
Accessories can help too. When using a smartphone whose screen is glare, the user needs to be prepared for the fact that vision problems will not take long. Even small reflections lead to eye strain. Getting rid of glare is easy - you need to stick a matte film on the screen. This accessory is inexpensive and also durable. As a bonus, the matte film will protect the display from scratches and fingerprints.
Another useful tool is contact lenses with HD optics. Lenses reduce eye strain even when the user is reading from a mobile device in poor light or with regular light changes. Lenses with high-definition optics from the company Bausch & Lomb.
Proper nutrition - an assistant to an advanced user?
Vitamin A has a positive effect on vision. It is found in large quantities in fish, blueberries, carrots, eggs - these are the foods that should be emphasized in the diet of a person who suffers from "gadget addiction". However, it is important to remember that eating well is not enough to preserve vision. It has been calculated: in order to compensate for the damage that gadgets cause to the eyes, a person needs to eat 5-6 kg of carrots every day.
Should I be worried about my eyesight if I wear lenses or glasses?
Constant “talking” with a smartphone also has a negative impact on the vision of people who use contact lenses or wear glasses. If, let's say, on debt of work, a person is forced to constantly "sit" in the smartphone or at the computer, it is recommended to contact an ophthalmologist. The doctor will help you choose the optics taking into account the health of the eyes and professional activity of a person.
What can advise readers?
There are several recommendations for those who do not think the ride in the subway or in a taxi without reading. First of all, such people should think about the acquisition of of the electronic book with technology E-INK. Such books do not have the backlight, the pages of them are visually similar to ordinary paper, the font value can be adjusted by anything - due to this negative impact on vision is minimal. Plus e-books E-INK lies in long stand-alone work - as the energy is consumed only on the transfer of pages, the device can do without recharging a whole month. Minus - High Cost: E-books have recently rose in general, and the device E-INK will cost the buyer in the amount of about 10 thousand rubles.
