Difference Between 1.75 Power and 2.00 in Reading Glasses

Steve Mower - November 2019

Printing out our reading nautical chart and following the instructions carefully will provide you with a very good idea as to the reading power y'all need, whether for upward close reading or monitor viewing. Getting an center exam is the all-time way to decide exactly what kind of correction yous demand for whatsoever distance. Possible factors like astigmatism for example, when corrected, can improve your vision dramatically. You lot won't know until you get an eye exam. Also, using data from a written prescription, like using the 'Add' power as your reading ability for readers, is ordinarily wrong. Actually, but get an heart exam. (Prescription lenses hither are only $ten.00 more!)

If you already have a prescription yous can accept us look at it and offering recommendations.

(Note: You tin can test each eye individually by covering 1 middle with a slice of paper. Go along both optics open though.) Read the instructions below the chart.

All you demand to practice is Right Click on the above image and click to view paradigm, or save it to your estimator'south hard drive. And then print out the eye chart. Make sure you print it in its real, original size. The terminal printed chart should be 5 inches wide (12.7cm).

Once you have printed out the chart, simply follow these instructions: If you are wearing readers, yous demand to take them off for the exam.

Note for READING OVER CONTACT LENS WEARERS - If you clothing Distance Vision Only contact lenses and need reading spectacles, yous can use these charts, just make certain you are wearing your contacts.

In one case y'all have printed the reading chart, follow these instructions:

Reading Glasses Strength For Up-Close Vision (approx. 12-xiv inches away)

1. Without reading glasses on, agree the chart at a comfortable reading distance for you. Most people read at about 12-14 inches abroad.

2. Read the nautical chart from bottom to top. (Note: Yous tin test each middle individually by covering one center with a piece of paper. Keep both eyes open though)

iii. The first line yous have difficulty with is the power of lens you need.

If you are in the +3.00 and up range, I recommend choosing the next power lower than you think you might need. For example, if you accept issues seeing the +4.00 line but are 'kind of' comfortable with the +three.25 line cull +3.fifty every bit your power.

Tip one: If y'all do a lot of close upward piece of work and reading (12 inches or closer) yous can opt for a higher power. Closer work=college power.

Tip 2: After y'all determine your power, write it down and so do the test again for each eye individually. Comprehend your left center with a thick piece of paper and test your correct heart. Then do the aforementioned with your left heart. Write your correct and left powers down. Are they the same or different? (We can make your reading glasses with the aforementioned or different powers)

Reading Glasses Strength For Computer Distance Reading (approx. Arm'southward length)

one. Follow the instructions for determining Up- Close Vision above. Make sure you hold the chart at 12-xiv inches away and no further.

2. Once y'all have determined your reading glasses strength, use the chart below to determine your computer altitude strength.

Note; The reckoner strength powers listed are for screen distances of arm'due south length (approx 18 inches). If your screen is closer than arm'south length yous can opt for the next step higher power. BTW, run into tip 2 above. (Note: Yous can test each centre individually by covering 1 middle with a slice of newspaper. Keep both optics open though)

Upwardly-Close Power	Computer Power
+0.50	No Need
+0.75	+0.25
+ane.00	+0.50
+ane.25	+0.fifty
+1.l	+0.75
+i.75	+0.75
+2.00	+1.00
+2.25	+i.00
+2.50	+1.25
+2.75	+1.25
+3.00	+1.50
+iii.25	+one.50
+3.l	+1.75
+iii.75	+i.75
+4.00	+ii.00
+4.25	+2.00
+4.fifty	+2.25
+4.75	+2.25
+5.00	+2.50

[DISCLAIMER: The resulting reading strengths, if the instructions are followed advisedly, should exist accurate. However, in that location is no substitute for an eye exam from an Optometrist or Ophthalmologist. You may crave a correction for astigmatism for example...]

Need unlike powers in each middle? We practise that!
