Frequently asked questions

• At what age do children’s consultations begin and why are they important?

       Consultations in children begin approximately at the age of three, but if the child has visible problems from birth, or problems appear after a short time, certain specialized analyzes can be done, from which we can determine what treatment is beneficial in the first phase. The importance of this consultation is given by the fact that certain eye problems can be treated relatively easily, only until the age of 9, that is until the eyeballs mature and the muscles stiffen.

• What distance from the display is recommended for the eyes?

       In order to find out the optimal distance from the display you use, you must choose the size of the text corresponding to the one you generally use, or possibly a smaller text, for a more accurate approximation. There are two ways to check your optimal distance from the display: the simplest is to approach and move away from the display until the text becomes the clearest, and the second is to display this text on a red and green background. You need to move closer and further from the display until the text is clear on both colors. R/V test

• Why do my eyes get tired when I work at the computer or read, and why do I have to take breaks?

       In order to be able to work efficiently in a close environment and maintain a clear and relaxed view throughout the day, we must know that clear vision at different distances is supported by the accommodation of the crystalline. Thus, when we look at objects at great distances, over 6m, the ciliary muscles that coordinate the crystalline are relaxed and when we look into the work environment close, 20cm-1.2m, the ciliary muscles are in tension. So, we can deduce that at a certain time interval we are forced to relax the ciliary muscles, like any other muscle in the body that is, to look at a great distance for a short period of time, also called “break from close work”.

• How long does it take and what is a break?

       A break means moving the gaze from the work environment to the farthest corner of the room, at as far distance as possible (over 6m), or closing the eyes for 20 seconds, at a certain time interval.

• How often do you have to take these breaks?

     The time interval at which we are forced to take breaks is set according to the state of eye fatigue of each person, approximately between 10 and 45 minutes. In the morning, when we start working in the environment, the ciliary muscles have a good tone and enough strength to support the accommodation of the crystalline for a clear and relaxed view of up to 45 minutes.

     During a working day it is recommended that in the morning we take these breaks at a greater interval of time, after 35-45 minutes, at noon is recommended to take a break more often, after 20-25 minutes, and in the evening after 10-15 minutes, if throughout the day we work from a close distance from the display.

• What happens if you don’t take these breaks?

      At the moment, when we forget about these breaks and continue working in a close environment, after about an hour of tension, the ciliary muscles enter into a slight spasm that, if sustained, leads to the appearance of mild sensomatic states: in the first phase (dry eye sensation, itching, redness, etc.) to headaches and dizziness. If this behavior is repeated daily, it can lead to myopia (up to about 23-25 years old) or it may increase the dioptric values of a person who already has myopia(up to 60-65 years old in certain cases).

   People over the age of 23 who have a corrected myopia and who have been told that myopia will cease to increase after this age, if you will make excesses of accommodation through study or job, you will notice an increase in myopia directly proportional to the accommodative excess made by each one and possibly an increasingly accentuated photophobia!

      Galloping/strong myopia is myopia that has a rapid growth, even after the period of physiological growth, and the person in question has very high dioptric values.

    The slow growth of myopia, with dioptric values increased by 0.25 – 0.75dpt / year, is caused by the excesses of accommodation after the cessation of physiological growth!

• Why are we forced at a certain age to wear close-up glasses?

      Due to the decrease in the accommodation amplitude of the crystalline (responsible for good vision at different distances) that have a perceptible stiffening period between 45 years and 60 years. Crystalline Accommodation Table

• Why do problems with remote vision arise after wearing the close-up glasses for a while?

      Due to the incorrect use of the close-up glasses! It is totally forbidden to look through the glasses at greater distances than the diopter that you have allows you to. To find out the distance at which you see best with the close-up glasses, that is, the distance that theoretically you do not have to overcome when wearing those glasses, you can do the following exercise: You look at a text in small characters but that you can read, approach and distance the text until it is no longer visible. You will notice a minimum and maximum distance at which you can perceive the text, the average of these distances is the point where your eyes converge perfectly to the text read, that is, the distance at which you see most clearly with those glasses, and you should not exceed it when wearing them!

• What does progressive lenses mean, when are they used and what are their benefits?

      Progressive glasses are used after the age of 45-50 years, when the difference between the diopter from a distance (0 if you don’t have problems) and the close one is more than a diopter (the personal recommendation is after the difference exceeds 1.5 dpt, because up to this level the crystalline has some flexibility and still helps). From the name of the (progressive) lenses we deduce that it is a dioptric progression between the diopter of distance and the close-up. If you have 0 at a distance and +1.50 up-close, then the lenses will have a step progression of 0.25 dpt. from 0 to +1.50. Due to this progression we have improved vision at different distances because the diopter is directly related to the distance at which you want to look (D=m at the power -1). In principle, the progressive lens will also help us to see well at intermediate distances (approximately between 40 cm and 1.0m), not just near or at a distance (bifocal lens).

     However, these lenses are not recommended in the office if you are working on the desktop, since the position of the head to see well at the intermediate distance is not correct. In this case, degressive lenses are the solution, lenses that have a progression only for close and intermediate distances. If in the office we use a laptop, then the situation changes, and a progressive lenses can also be worn in certain cases.
