How to test your eyesight

They say that the eyes are the window to the soul. And how we all want this mirror to be always clean and clear. After all, for a person with one hundred percent vision, it is even scary to imagine that one day the "picture" will fade or disappear altogether. When every day is able to observe thousands of bright colors, it’s scary to think about the bad. However, there are different cases in life and no one is immune from anything. That is why it is necessary to monitor the condition of the eyes and periodically check the quality of vision. After all, it all starts small. And sometimes even slight minor changes can lead to permanent wearing of glasses or even surgery.

How to test your eyesight at home

It is impossible to test your eyesight one hundred percent on your own. But you can make sure it's good by measuring the pungency. But then, based on the results of independent research, decide whether you should seek help from a specialist. Or you are satisfied with the data you received.

Visual acuity is the ability eye distinguish several points with a minimum distance between them.

There are several ways to test your eyesight yourself:

1. Using the Sittsev test. Eyesight is checked using a special plate. It is freely available on the Internet (shown below). Just print it on A4 paper and stick it to the wall. Move back some distance (about five meters). One eye is covered with a sheet (or palm), the main thing is not to squint or squint. And start naming the letters in order. Pronunciation of one letter should last no more than 3 seconds. If you name ten rows of letters without mistakes, then you have one hundred percent vision. If you have errors in one or more rows, you should contact a specialist for help.
2. There is such an eye disease as myopia and hyperopia. You can just as easily check the presence of one of them at home using a special colored table (given below). It has two colors. It must be printed on a color printer at maximum brightness. It is not recommended to check your eyesight while looking at the computer. Since the brightness of the monitor can play a cruel joke with you.
   The leaf, as in the previous case, is hung on the wall, at eye level. Move back some distance. The result is determined as follows. If you see red much brighter and clearer, then you have myopia. If the brain perceives green in this quality, then farsightedness.

Check your child's eyesight

Eyesight test baby is not very different from an adult vision test. You can use the same methods. It is very important that the child has good eyesight, because he is just beginning to learn about the world and he has a lot to learn. However, not one child since birth does not know letters and cannot read, which is why a special table consisting of figures and symbols has been created for them. The principle of operation is exactly the same as that of the Sittsev test.

Vision test chart

There are the following tables for eye examinations:

• The already mentioned Sittsev Table. It is most commonly used to test eyes. Consists of twelve lines of letters that decrease from top to bottom. The optimal distance at which a person should distinguish between letters: lower - two and a half meters; the upper ones are five.
• Snelen's table. It is used in countries where English is used. Similar to Sittsev's table.
• Golovin's table. This type of table is aimed at checking visual acuity. It looks like a set of rings with the same height and width with breaks. It is considered to be the norm if the human eye distinguishes two distant points with an angular resolution of one minute. Checking distance from five meters.

Where can you get your vision checked
