MySpex readers are available in multiple lens strengths, from +1.00 to +3.00. Use this chart to find out what lens strength is appropriate for you.
Print the chart below on a 8.5" x 11" paper. Be sure to print it out as is. Do not adjust it to 'Fit to Page' or change the zoom.
Place the chart about 12-14 inches away from your face, or where you would normally hold a book or newspaper.
With your glasses off, begin to read the lines from top down. The first line you have difficulty reading is your lens strength.
Some MySpex lenses are available in +0.25 increments. If your first difficult line is extremely blurry, consider choosing the strength in between.
If you receive your glasses and they are not the appropriate lens strength, we will gladly exchange your readers within 12 months of your original purchase. Read more on our Warranty Page.
