Reading Glasses Strength and Reading Test
For your convenience we have a simple way for you to determine what reading glasses or computer glasses strength to use. Our reading glasses strength chart:
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. Then print out the eye chart. Make sure you print it in its real, original size. The final printed chart should be 5 inches wide.
Once you have printed out the chart, just follow these instructions:If you are wearing readers, you need to take them off for the test.
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 contacts.
Once you have printed the reading chart, follow these instructions:
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 1: 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.
Tip 2: After you determine your power, write it down and then do the test again for each eye individually. Cover your left eye with a thick piece of paper and test your right eye. Then do the same with your left eye. Write your right and left powers down. Are they the same or different? (We can make your reading glasses with the same or different powers)
Reading Glasses Strength For Computer Distance Reading (approx. Arm's length)
1. Follow the instructions for determining Up- Close Vision above. Make sure you hold the chart at 12-14 inches away and no further.
2. Once you have determined your reading glasses strength, use the chart below to determine your computer distance strength.
NOTE; The computer strength powers listed are for screen distances of arm's length (approx 18 inches). If your screen is closer than arm's length you can opt for the next step higher power. BTW, see tip 2 above. You can do this test for each eye individually.
Up-Close Power Computer Power
+.50 No Need
+.75 No Need or +.50
DISCLAIMER: The resulting reading strengths, if the instructions are followed carefully, should be accurate. However, there is no substitute for an eye exam from an Optometrist or Opthamologist. You may require a correction for astigmatism for example...

You can select a different power for each eye. If you need a different power for each eye, we can save you a lot of money. Our lenses are free. Buying prescription readers would cost you 2 to 5 times more in a store. Why would you do that?
You can add AR Coating or Custom Tint. Our Mojo BluBlock AR (anti-reflective) coating is great for computer use to cut reflected glare and filter out unwanted blue light. Our custom tints look cool and our Mojo BluBlock tints help elleviate problems with blue light emitting devices like cell phones, tablets, and iPads.
