Adapt reading to avoid tired sight
Given the lack of time, it is common to read in unusual places, such as on the bus, in bed and in dark environments. But can these reading habits hurt vision? According to the ophthalmologist Wagner Ghirelli, in fact, the more we read, the better. "Those who read a lot have a better visual capacity and read faster," he says. "With the use of the computer, there are people who become very agile and develop very great visual ability, since they associate visual and motor skills."
Reading on the bus is bad?

"The problem in the retina is related to trauma and independent of habits related to reading," explains the ophthalmologist Omar Assae.

In adults, reading with the book too close can cause discomfort at the most.
For good reading
More than worrying about rumors, you have to pay attention to small attitudes that will certainly ensure greater comfort during reading:
- Regardless of whether it is a book, a tablet, etc., the object should be approximately 40 cm away from the eyes, with adequate luminosity (determined by the comfort feeling when reading);
- O The object of reading should always lie below the eyes, nothing to lie in bed and place the book above them;
- Lighting is an important ally of reading and can not disturb vision, either by lack or by excess. Although comfort is relative, Osmar Assae recommends a 60w bulb, which should provide sufficient illumination.
