Wearing a small one looks slim, but it can't be too small to wear. The degree of glasses is the same, and the degree of deviation cannot be seen clearly. Generally, the optical shop will not match the degree of matching glasses for adults, that is, consider the use of computer writing and reading. Therefore, the contrast between red and green is generally clear, and you can wear glasses to compare. In the case of the subject, I will say two more words. If the degree is properly lowered, I can't estimate it myself. I have to consider the balance of my eyes. Too much reduction in the degree of not only prevents vision, but the eye is more likely to be tired.
