So by wearing progressive lenses glasses, it is likely to have all the field of vision, such as distant, intermediate, or near things. But on the other hand, for most people, it will take some time to adjust to them. And at this period, side effects like headaches and visual dizziness can often occur. So in other words, we can say that progressive lens glasses can not be completely free from visual side effects. During the accommodation period, many people will experience headache and visual dizziness.
