Seeing Without Glassesdoes not advocate throwing away your glasses or contacts; rather, it instructs you about how to use glasses as therapeutic tools, just as you might use a set of free weights or a racquet to tone your body. Neither does the book recommend abandoning your optician; rather, it teaches better use of them as an educator and resource. Businesses benefit as productivity increases when their employees use preventive techniques to avoid computer eyestrain and to reduce the negative side effects of vision stress. Seeing Without Glassesis a valuable handbook for anyone looking to improve their vision or to maintain healthy eyesight.
