We are here to help. At Rx-Safety, we sell all different types of glasses—including prescription glasses. We take seen the conversion process many times, so nosotros want to do our part to demystify this process.
Below y'all will detect our guide to converting your eyeglass prescriptions to reading glasses. By following the steps and communication that we have presented beneath, you will exist well on your fashion to completing this important chore.
The Conversion Process
To convert to reading glasses, you only need two things. You will need your current eyeglass prescription and a calculator. From in that location, you will do some simple math to ensure that your conversion is accurate.
Let's start with your current eyeglass prescription. Every eyeglass prescription contains several abbreviations and numbers. For instance, "OD" stands for oculus dexter ("right heart" in Latin) and "OS" stands for oculus sinister ("left eye"). To successfully convert your eyeglass prescription to reading spectacles, you volition need several other metrics. You volition need a distance prescription, sphere power, and an add. The distance prescription is cocky-explanatory. Sphere ability is the main strength of your eyeglass prescription, and information technology is written in increments of 0.25. The add together 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 together ability. To illustrate this process, information technology is helpful to provide some examples.
For instance, allow's say that you have an eyeglass prescription that has a sphere power of -1.25, a cylinder of -1.00, an centrality of 83, and an add of ane.50. Once again, the formula states that we should add our sphere power (-one.25) to our add together power (1.50), resulting in plus 0.25. From here, if this were to become a unmarried vision reader, the finish result would be plus 0.25, minus 1.00, at 83 degrees.
Equally some other example, if nosotros had a sphere power of 2.00, a cylinder of -one.50, an axis of 130 degrees, and an add of 1.l. We would follow the aforementioned steps as above. Merely put, we would add the sphere power of 2.00 to the add of i.50, resulting in plus 3.50. The last prescription reading for these reading glasses would be plus three.50, minus one.50, at 130. Past this point, yous can see that both the cylinder and axis are never going to modify. The just thing that will alter volition exist the sphere power because we are calculation the added power to it. Uncomplicated enough, right?
This conversion formula can atomic number 82 to some interesting scenarios. For instance, if you have a sphere power of -i.50 and an add together of 1.50, you will end up with 0.00. Y'all would be wearing a single vision reader of 0.00 and this will be included with the same cylinder and axis.
The state of affairs becomes somewhat more complicated if your sphere power is not the aforementioned for both eyes. As but one instance, let's say that your correct centre 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 same for both eyes. For instance, let'southward assume that your cylinder is -0.75, your centrality is 140 degrees, and your add together is 1.l. From in that location, you would follow the same formula equally described above. Specifically, you would have your right heart sphere power of -iii.fifty and add together it to your add (1.50), resulting in -2.00. For your left eye, y'all would take -two.75 and add information technology to 1.50, equalling -one.25. This would result in a right eye of -ii.00, -0.75 at 140, and a left eye of -ane.25, -0.75 at 140. It is every bit simple as that.
Every bit y'all tin see, the math itself isn't that catchy. The one thing that could trip you up, all the same, is the add-on of both positive and negative numbers. Information technology 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 reckoner when you lot are doing this conversion. Have your time and don't hesitate to bank check your math twice. If you put on your reading glasses and think that something is off, go dorsum and see if you lot correctly fabricated your conversion. While you lot will somewhen get it right, you can avoid some frustration and wasted fourth dimension by going irksome and checking your math.
Confidently Converting Your Eyeglass Prescription to Reading Glasses
By this signal, we promise yous accept realized that information technology isn't an extremely complicated process. Aye, information technology does crave y'all to practise some simple algebra. If you feel like you're weak at math, yous may be intimidated by this fact. Luckily, however, the algebra is extremely basic. Slowing down, being deliberate, and checking your piece of work is an constructive playbook here.
Therefore, nosotros encourage you to try it out for yourself today. If it would make you lot experience more comfy, feel gratuitous to do some hypothetical conversions first. Completing practice conversions earlier real-life conversions will brand you more comfortable with the math and volition requite you the confidence to movement forward. One time you are more confident, however, feel free to try the conversion on yourself. If you accurately complete the conversion, that's great! If not, you volition chop-chop find, and you can course-correct as necessary.
We wish you the best of luck!
