Advice for tourists: how to read and use glasses correctly so as not to spoil your eyesight?

We read on various modern high-tech gadgets: computers, laptops, smartphones, the latter are always with us, we read with them even on the road. 

But for many people, this is not enough: for them, real reading is a book, no matter if it is a paper or electronic version. Such bookworms read a lot, for a long time and constantly. How harmful is prolonged reading for the eyes and how to read correctly in order to preserve vision? 

Is there any harm from reading? 

Small print in books really sets a heavy load on the human visual system. Trying to distinguish between letters, moving quickly from line to line, the muscles of the eyes constantly tense up for a long time. However, by nature, the organs of vision are intended for this, therefore, reading is not capable of leading to destructive disorders in the eyes and worsening the sharpness of our optical system. 

However, a number of factors can cause not only fatigue and dry eyes, but also headaches, tension in the cervical region: 

Weak or too bright lighting 

When there is not enough light, a person brings the book closer to him, the eye muscles begin to tighten more, increasing intraocular pressure. Constant reading in poor lighting can even cause myopia. Excessively bright light, which literally blinds, also leads to a large overstrain of the visual system. 

Reading while lying down 

This position also makes you bring the book closer, hold its at the right distance is almost impossible. The result is eye fatigue and a headache. 

Reading an e-book or on a smartphone

Cons: small screen size, which forces the reader to bring the screen closer to the eyes, and blue LED backlighting of digital displays, unsafe for health. 

Reading in transport 

The vibration of the transport is transmitted to the book, a person may not even notice it. Plus poor lighting. In transport, the eyes get tired faster, pain may occur. 

Advice for those who wear glasses 

People with ophthalmic diseases who are forced to wear corrective glasses should worry about their vision more than others. Excessive strain on the visual muscles that occurs when reading can significantly aggravate the situation. 

Special problems arise in people after 40 years, when farsightedness develops. They are forced to wear glasses while reading, as they no longer distinguish between small print in books or icons on a smartphone. At the same time, they can clearly see all objects in the distance. Optometrists recommend them to purchase glasses with narrow lenses, in which you can look over the lenses when looking into the distance. Examples for clarity – narrow rectangular frames Jaguar 3372 007 or Porsche Design 8801 A, which also look stylish. 

The second tip is not to rush to buy ready-made reading glasses. For refractive errors, custom-made glasses are ideal. In the prescription, the doctor will indicate your individual interpupillary distance horizontally and vertically. Finished glasses are produced with an average interpupillary distance of 62-64 mm, and the optical center of the lenses is located geometrically in the center of the frame. As a result, the optical power of finished glasses can differ significantly from what you need. As a result, ready-made glasses will provide you with a headache, tearing, pain in the eyes. 

In addition, ordering glasses according to an individual prescription, you can choose a frame to your taste and size, taking into account the latest fashion trends. For example, semi-rimless Clubmaster RX 5154 8117 Marble Optics with original tortoiseshell print or folding, pocket version Persol 2886V 24 Folding, convenient for people with farsightedness. It is now easy to find a sale of Ray-Ben glasses on the Web at a discount and choose the right model from collections of different years.

The rest of the rules are simple and may seem boring in a school way, but following them will help preserve your eyesight:
