Therefore, it is critical to recognize and understand the common steps in this procedure.
We are here to help. At Rx-Rubber, we sell all different types of glasses—including prescription glasses. We have seen the conversion process many times, then nosotros want to do our part to demystify this process.
Below you lot will find our guide to converting your eyeglass prescriptions to reading glasses. Past following the steps and advice that we have presented below, you will be well on your way to completing this important task.
The Conversion Procedure
To convert to reading glasses, you only need ii things. You lot will demand your current eyeglass prescription and a calculator. From in that location, you volition do some uncomplicated math to ensure that your conversion is accurate.
Permit'south start with your current eyeglass prescription. Every eyeglass prescription contains several abbreviations and numbers. For case, "OD" stands for oculus dexter ("right center" in Latin) and "OS" stands for oculus sinister ("left centre"). To successfully convert your eyeglass prescription to reading glasses, you lot will need several other metrics. You lot volition need a distance prescription, sphere power, and an add. The distance prescription is cocky-explanatory. Sphere power is the main forcefulness of your eyeglass prescription, and it 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 glasses is adding your sphere power to your add power. To illustrate this process, it is helpful to provide some examples.
For instance, let'southward say that y'all take an eyeglass prescription that has a sphere ability of -1.25, a cylinder of -1.00, an axis of 83, and an add together of 1.l. Once again, the formula states that we should add together our sphere power (-one.25) to our add ability (1.50), resulting in plus 0.25. From hither, if this were to become a single vision reader, the finish result would be plus 0.25, minus 1.00, at 83 degrees.
Equally another example, if we had a sphere power of 2.00, a cylinder of -1.50, an axis of 130 degrees, and an add together of i.l. Nosotros would follow the aforementioned steps as higher up. Simply put, nosotros would add together the sphere ability of 2.00 to the add of 1.50, resulting in plus three.50. The last prescription reading for these reading glasses would be plus 3.50, minus 1.50, at 130. Past this signal, you can see that both the cylinder and axis are never going to modify. The merely thing that will change will be the sphere power considering nosotros are adding the added power to it. Simple enough, right?
This conversion formula can pb to some interesting scenarios. For case, if you accept a sphere power of -i.50 and an add of 1.50, yous will terminate upward with 0.00. Yous would exist wearing a single vision reader of 0.00 and this will be included with the same cylinder and centrality.
The situation becomes somewhat more complicated if your sphere power is not the same for both optics. As merely one case, permit's say that your right heart has a sphere ability of -3.50 and your left eye has a sphere power of -2.75. The remaining parts of your prescription are the same for both eyes. For instance, allow'south assume that your cylinder is -0.75, your axis is 140 degrees, and your add is 1.50. From in that location, you would follow the aforementioned formula every bit described higher up. Specifically, you would take your right eye sphere power of -3.fifty and add it to your add (one.l), resulting in -2.00. For your left centre, you would take -2.75 and add it to 1.l, equalling -one.25. This would issue in a right eye of -two.00, -0.75 at 140, and a left middle of -1.25, -0.75 at 140. It is equally simple every bit that.
As y'all can see, the math itself isn't that tricky. The ane thing that could trip you upwardly, however, is the addition of both positive and negative numbers. It is easy to mix your signs, which could result in reading spectacles that are not properly converted for your eyesight. Because of this, it doesn't hurt to take a figurer when you lot are doing this conversion. Take your fourth dimension and don't hesitate to cheque your math twice. If you put on your reading glasses and recollect that something is off, go back and see if you correctly made your conversion. While yous will eventually go information technology right, you can avert some frustration and wasted time by going slow and checking your math.

Slowing downwardly, beingness deliberate, and checking your piece of work is an effective playbook here.
Therefore, nosotros encourage you to effort it out for yourself today. If it would make you feel more than comfortable, feel free to do some hypothetical conversions first. Completing practice conversions before existent-life conversions will make you more than comfortable with the math and will give you the confidence to move forward. One time you are more than confident, however, feel free to try the conversion on yourself. If you lot accurately complete the conversion, that's great! If not, you volition quickly discover, and you tin can grade-correct as necessary.
