You will have the best results with your magnifier purchase if you have guidance from a vision rehabilitation professional. The strongest magnification is not necessarily the best option: a too-strong or too-weak magnifier will not have the desired results. A person will see best with instruction in positioning the magnifier.
When you purchase your magnifier at Second Sense, make an appointment at 312-236-8569. Let us know if you would like some instruction on proper magnification use.
