We are here to help. At Rx-Safety, we sell all different types of glasses—including prescription glasses. We accept seen the conversion process many times, so we want to practise our part to demystify this process.
Below you will find our guide to converting your eyeglass prescriptions to reading glasses. By following the steps and advice that we have presented below, you lot will be well on your way to completing this important chore.
The Conversion Process
To catechumen to reading glasses, yous only need two things. You will need your current eyeglass prescription and a calculator. From there, you will do some simple math to ensure that your conversion is accurate.
Allow's start with your current eyeglass prescription. Every eyeglass prescription contains several abbreviations and numbers. For instance, "OD" stands for oculus dexter ("correct heart" in Latin) and "Bone" stands for oculus sinister ("left eye"). To successfully convert your eyeglass prescription to reading glasses, you volition demand several other metrics. You will demand a distance prescription, sphere ability, and an add. The distance prescription is cocky-explanatory. Sphere power is the main strength 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 spectacles.
Essentially, the formula for converting an eyeglass prescription to reading glasses is adding your sphere ability to your add together power. To illustrate this process, information technology is helpful to provide some examples.
For instance, permit's say that y'all accept an eyeglass prescription that has a sphere ability of -ane.25, a cylinder of -1.00, an centrality of 83, and an add together of i.50. Once once more, the formula states that we should add together our sphere ability (-1.25) to our add ability (ane.fifty), resulting in plus 0.25. From here, if this were to go a single vision reader, the end result would be plus 0.25, minus ane.00, at 83 degrees.
As some other example, if we had a sphere ability of two.00, a cylinder of -i.50, an axis of 130 degrees, and an add of 1.50. We would follow the aforementioned steps as to a higher place. Simply put, we would add together the sphere power of 2.00 to the add of 1.50, resulting in plus three.50. The final prescription reading for these reading glasses would be plus three.50, minus 1.fifty, at 130. By this point, you can see that both the cylinder and axis are never going to alter. The only matter that volition change will exist the sphere power because we are adding the added power to it. Unproblematic enough, right?
This conversion formula can lead to some interesting scenarios. For instance, if you accept a sphere power of -1.50 and an add of 1.50, you will finish up with 0.00. You lot would be wearing a single vision reader of 0.00 and this will exist included with the same cylinder and axis.
The situation becomes somewhat more complicated if your sphere power is not the same for both eyes. As just 1 instance, let'due south say that your correct eye has a sphere power of -3.50 and your left eye has a sphere power of -2.75. The remaining parts of your prescription are the aforementioned for both eyes. For instance, let'southward assume that your cylinder is -0.75, your centrality is 140 degrees, and your add together is ane.fifty. From in that location, y'all would follow the same formula every bit described in a higher place. Specifically, you would accept your right eye sphere ability of -3.50 and add it to your add (1.l), resulting in -2.00. For your left eye, you would take -2.75 and add it to one.50, equalling -1.25. This would result in a right middle of -2.00, -0.75 at 140, and a left eye of -1.25, -0.75 at 140. Information technology is as simple as that.
Equally you can see, the math itself isn't that tricky. The one thing that could trip y'all up, notwithstanding, is the add-on 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. Considering of this, information technology doesn't hurt to accept a calculator when you lot are doing this conversion. Take your time and don't hesitate to check your math twice. If y'all put on your reading glasses and call up that something is off, get back and see if you lot correctly fabricated your conversion. While you will eventually get it right, you can avert some frustration and wasted fourth dimension past going deadening and checking your math.
Confidently Converting Your Eyeglass Prescription to Reading Glasses
By this point, we promise y'all have realized that it isn't an extremely complicated process. Yep, it does crave you to practice some uncomplicated algebra. If you lot feel like you're weak at math, y'all may be intimidated past this fact. Luckily, notwithstanding, the algebra is extremely bones. Slowing downwards, being deliberate, and checking your work is an effective playbook here.
Therefore, we encourage y'all to try it out for yourself today. If information technology would brand yous experience more comfortable, feel free to do some hypothetical conversions first. Completing exercise conversions before real-life conversions volition make you more comfortable with the math and will requite you the confidence to move forward. Once y'all are more confident, nonetheless, feel complimentary to endeavor the conversion on yourself. If you lot accurately complete the conversion, that'south corking! If not, y'all will speedily notice, and you can course-correct as necessary.
