Nosotros are here to help. At Rx-Safety, nosotros sell all dissimilar types of glasses—including prescription glasses. Nosotros have seen the conversion process many times, and then we want to do our part to demystify this procedure.
Below yous volition find our guide to converting your eyeglass prescriptions to reading glasses. By following the steps and advice that nosotros take presented below, yous will be well on your way to completing this important task.
The Conversion Procedure
To convert to reading glasses, you only need two things. Yous will demand your current eyeglass prescription and a computer. From there, you will do some simple math to ensure that your conversion is accurate.
Permit's start with your electric current eyeglass prescription. Every eyeglass prescription contains several abbreviations and numbers. For case, "OD" stands for oculus dexter ("right centre" in Latin) and "OS" stands for oculus sinister ("left eye"). To successfully convert your eyeglass prescription to reading glasses, you will need several other metrics. You volition demand a altitude prescription, sphere power, and an add. The distance prescription is self-explanatory. Sphere ability is the principal force of your eyeglass prescription, and information technology is written in increments of 0.25. The add stands for the additional correction that is used for reading glasses.
Essentially, the formula for converting an eyeglass prescription to reading spectacles is adding your sphere power to your add power. To illustrate this process, information technology is helpful to provide some examples.
For example, let'due south say that yous have an eyeglass prescription that has a sphere ability of -one.25, a cylinder of -i.00, an axis of 83, and an add of 1.50. One time again, the formula states that we should add our sphere ability (-i.25) to our add together power (1.50), resulting in plus 0.25. From here, if this were to become a single vision reader, the end result would be plus 0.25, minus 1.00, at 83 degrees.
As another example, if we had a sphere power of two.00, a cylinder of -one.fifty, an axis of 130 degrees, and an add of 1.50. We would follow the same steps as above. Simply put, we would add together the sphere ability of ii.00 to the add together of ane.50, resulting in plus iii.50. The last prescription reading for these reading glasses would exist plus 3.50, minus 1.fifty, at 130. By this bespeak, you tin can see that both the cylinder and centrality are never going to alter. The only matter that will change will be the sphere power because nosotros are adding the added ability to information technology. Elementary enough, right?
This conversion formula tin lead to some interesting scenarios. For instance, if you accept a sphere power of -ane.50 and an add of 1.l, you will end upwards with 0.00. Yous would be wearing a single vision reader of 0.00 and this will be included with the aforementioned cylinder and axis.
The situation becomes somewhat more complicated if your sphere ability is not the same for both eyes. Equally merely one example, let'southward say that your correct eye has a sphere ability of -three.50 and your left centre has a sphere power of -2.75. The remaining parts of your prescription are the same for both eyes. For case, permit'southward assume that your cylinder is -0.75, your axis is 140 degrees, and your add is one.50. From there, you would follow the aforementioned formula as described to a higher place. Specifically, you would take your right centre sphere power of -iii.50 and add information technology to your add together (one.50), resulting in -two.00. For your left middle, yous would take -2.75 and add together it to one.50, equalling -one.25. This would result in a right eye of -2.00, -0.75 at 140, and a left eye of -1.25, -0.75 at 140. It is as simple as that.
As you can come across, the math itself isn't that tricky. The one matter that could trip yous up, withal, is the addition of both positive and negative numbers. It is piece of cake to mix your signs, which could result in reading glasses that are not properly converted for your eyesight. Because of this, it doesn't hurt to have a calculator when you are doing this conversion. Have your time and don't hesitate to bank check your math twice. If yous put on your reading glasses and think that something is off, go back and come across if yous correctly made your conversion. While you will eventually go it right, you tin avoid some frustration and wasted fourth dimension by going tiresome and checking your math.
