HOW TO DETERMINE WHICH READING STRENGTH IS RIGHT FOR YOU: All you need to do is Right Click on the above image and click to view image, or save it to your computer's hard drive.

Note for READING OVER CONTACT LENS WEARERS - If you wear Distance Vision ONLY contact lenses and need reading glasses, you can use these charts, just make sure you are wearing your contactINSTRUCTIONS: Reading Glasses Strength For Up-Close Vision (approx. 12-14 inches away) 1. Without reading glasses on, hold the chart at a comfotable reading distance for you. Most people read at about 12-14 inches away. 2. Read the chart from bottom to top. 3. The first line you have difficulty with is the power of lens you need. If you are in the +3.00 and up range, I reccommend choosing the next power lower than you think you might need. For example, if you have problems seeing the +4.00 line but are 'kind of' comfortable with the +3.25 line choose +3.50 as your power. Tip: If you do a lot of close up work and reading (12 inches or closer) you can opt for a higher power. Closer work=higher power
