Coçar os
olhos e ler no escuro ou deitado podem prejudicar a visão?



Cerca de 80% das informações que
recebemos chegam pelos olhos.
Ideal, segundo médico, é não apagar luz para usar computador ou ver TV.







A visão é
um dos mais importantes meios de comunicação com o ambiente, já que cerca de
80% das informações que recebemos chegam pelos olhos.

Alguns
hábitos corriqueiros, como coçar a vista e ler no escuro ou deitado, podem ser
prejudiciais à visão.
Ler com o livro muito perto pode forçar o
cristalino (espécie de diafragma do olho) e favorecer a miopia. Também pode ser
um sinal de que a pessoa já sofre de algum problema de refração. A distância
mínima ideal é de 30 cm, segundo o oftalmologista Samir Bechara, do Hospital
das Clínicas de São Paulo.&nbsp;

Já ler
deitado propicia um achatamento dos olhos, o que é ruim para a saúde deles. E
ler no escuro dilata a pupila e causa desconforto. Por isso, o melhor é não
apagar a luz para usar o computador ou ver TV. Você corre o risco de se cansar
mais e ficar com dor de cabeça.







No caso
de ler em um veículo em movimento, como carro, ônibus, trem ou metrô, há um
maior esforço dos músculos dos olhos para mantê-los paralelos, o que pode
provocar desconforto e favorecer o estrabismo.
