There are two forms of the test that you can take. When first starting, we recommend that you take the Quick Test. This test is comprised of three measurements per eye and will give you the Spherical Equivalent Values for your eyes. If you have low astigmatism, the SPHE is an accurate measure of your eyes' refractive correction. The measurements in the Quick Test do not count towards your final EyeGlass Number.
The Full Test measures your astigmatism and also is used to generate your EyeGlass Numbers. For each eye you will perform 9 measurements with each corresponding to a different angle. If you do not know whether you have astigmatism, we recommend taking taking the full test.
