Therefore, it is critical to recognize and understand the common steps in this process.
We are hither to aid. At Rx-Safety, we sell all different types of spectacles—including prescription glasses. We have seen the conversion process many times, so we want to do our part to demystify this process.
Below you will find our guide to converting your eyeglass prescriptions to reading spectacles. By following the steps and advice that we have presented below, yous will be well on your way to completing this important chore.
The Conversion Process
To convert to reading glasses, y'all merely demand two things. Yous volition need your current eyeglass prescription and a figurer. From there, you volition practice some elementary math to ensure that your conversion is accurate.
Let'south beginning with your electric current eyeglass prescription. Every eyeglass prescription contains several abbreviations and numbers. For instance, "OD" stands for oculus dexter ("right eye" in Latin) and "OS" stands for oculus sinister ("left eye"). To successfully convert your eyeglass prescription to reading glasses, you lot will need several other metrics. Y'all will demand a altitude prescription, sphere power, and an add. The altitude prescription is self-explanatory. Sphere ability is the main strength of your eyeglass prescription, and it is written in increments of 0.25. The add stands for the boosted 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 together power. To illustrate this process, information technology is helpful to provide some examples.
For instance, let's say that you have an eyeglass prescription that has a sphere power of -1.25, a cylinder of -1.00, an axis of 83, and an add of 1.fifty. Over again, the formula states that nosotros should add our sphere power (-1.25) to our add ability (ane.fifty), resulting in plus 0.25. From here, if this were to become a unmarried vision reader, the stop result would be plus 0.25, minus 1.00, at 83 degrees.
As another example, if we had a sphere power of 2.00, a cylinder of -1.50, an centrality of 130 degrees, and an add of 1.50. Nosotros would follow the aforementioned steps every bit higher up. Simply put, we would add together the sphere power of 2.00 to the add of 1.50, resulting in plus 3.50. The final prescription reading for these reading glasses would be plus iii.50, minus ane.50, at 130. By this point, y'all can run into that both the cylinder and axis are never going to change. The only affair that volition alter volition exist the sphere ability considering we are adding the added power to information technology. Elementary plenty, right?
This conversion formula can lead to some interesting scenarios. For example, if you have a sphere power of -1.50 and an add of 1.50, you lot will end upwards with 0.00. You 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 eyes. Equally just one instance, let'southward say that your right eye has a sphere power of -3.l and your left center has a sphere ability of -2.75. The remaining parts of your prescription are the same for both eyes. For instance, permit'due south assume that your cylinder is -0.75, your axis is 140 degrees, and your add is 1.50. From there, yous would follow the aforementioned formula as described above. Specifically, you would take your correct centre sphere power of -3.50 and add it to your add together (1.50), resulting in -2.00. For your left heart, you would have -2.75 and add it to i.fifty, equalling -1.25. This would issue in a right eye of -2.00, -0.75 at 140, and a left eye of -1.25, -0.75 at 140. Information technology is as unproblematic as that.
Every bit you tin can see, the math itself isn't that tricky. The i matter 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 non properly converted for your eyesight. Because of this, it doesn't injure to have a calculator when you are doing this conversion. Take your time and don't hesitate to check your math twice. If you put on your reading glasses and think that something is off, go back and see if you lot correctly made your conversion. While yous volition eventually get it correct, you tin can avoid some frustration and wasted fourth dimension by going slow and checking your math.
Confidently Converting Your Eyeglass Prescription to Reading Glasses
By this bespeak, we promise you have realized that information technology isn't an extremely complicated process. Yeah, it does crave you lot to do some simple algebra. If yous feel like you're weak at math, you lot may be intimidated by this fact. Luckily, however, the algebra is extremely bones. Slowing down, being deliberate, and checking your work is an constructive playbook here.
Therefore, nosotros encourage you to try it out for yourself today. If information technology would make you feel more comfortable, feel free to exercise some hypothetical conversions commencement. Completing practice conversions before real-life conversions volition make you more than comfortable with the math and will give you the confidence to move forward. Once you are more confident, however, feel free to try the conversion on yourself. If you accurately complete the conversion, that's keen! If not, you will rapidly find, and you tin course-correct every bit necessary.
