The effect of the visual correction with glasses was examined on the brain activation during reading sentences with characters presented in a stimulus image by using the fMRI. As the results. when stimulus images can be seen clearly, the brain activations were found in the classical language areas. In contrast. when the visual correction was good but the target images were blurred. or when the target images were clear but the correction was not sufficient. little activation were found in those areas. although lower visual areas and the frontal eye field/the premotor area were activated. The activations in the language areas would be much sensitive to whether the character images are readable or not.
