Every day, many people spend more and more time in front of the computer. For some, it's work-related, and they just can't do it any other way. Others deliberately spend precious time chatting on various social networks and on dating sites. It is not recommended to sit at the computer for a long time without interruption. Vision problems may occur.Constantly watching the monitor, our eyes strain and get tired. And the flickering screen irritates the eyesight. The same thing happens when reading documents for a long time. The letters seem to blur before my eyes. You have to strain your eye muscles to see the text. With regular prolonged eye strain, vision begins to decrease. But often there just isn't enough time to visit an ophthalmologist. You can check your eyesight from the comfort of your home.Vision checkups should be regular. People over the age of forty and children under 7 need to have their eyes checked every year. Teenagers under 17 years old - once every six months. For people under the age of 40 - once every two years. Those who have vision problems should constantly consult a doctor.Checking your eyesight at home is the most rational option - use the Golovin-Sivtsev table. Such tables are hung in ophthalmologists' offices. You can download the manual online or buy it at a bookstore. Children who cannot read have their eyesight checked using the Orlova table. Instead of letters, it shows pictures of different sizes.Do not print the table on glossy paper. Otherwise, the letters will glow when you read them. The table is installed 5 meters away from the person. The room should be well lit.There are 12 rows in the table, arranged from top to bottom. The size of the letters goes from larger to smaller. The vision parameters are indicated next to each line. Ideally, line 10 can be seen by a person with very good eyesight. Children have their eyes checked according to the same principle.You can evaluate your eyesight using the letter "E". She is depicted in different inverted angles. The length of each letter line should be 0.5 cm. A person who can see where a letter is turned from three meters away has good eyesight.All the methods listed above are rather arbitrary and do not give an objective picture.
