Can too much studying ruin your eyesight? Maybe. A German study has found that the more education a person has, the greater the likelihood that he will be nearsighted.
The researchers did ophthalmological and physical examinations on 4,685 people ages 35 to 74. About 38 per cent were nearsighted.
But of those who graduated after 13 years in the three-tiered German secondary school system, about 60.3 per cent were nearsighted, compared with 41.6 per cent of those who graduated after 10 years, 27.2 per cent of those who graduated after nine years and 26.9 per cent of those who never graduated.
The percentage of myopic people was also higher among university graduates.
