What Does 1.75 Mean For My Prescription Eyewear?

Whether you are purchasing your first pair of prescription eyewear or have been wearing prescription eyewear for some time, we’re sure that you have at least glanced at your eye prescription. Especially if you are a new wearer of prescription glasses, the letters, numbers, and characters in your prescription may be confusing. It may seem like its own language. What’s even more confusing is that when speaking with your optician, optometrist, or eyewear retailer, your counterpart may state that you have a prescription of 1.75. Even though you may not necessarily need to know what that means, you may be naturally curious. Moreover, if you have a prescription of 1.75 and are searching for a new pair of prescription eyewear, knowing what this actually means can make your shopping experience much more pleasant.

In this article, we are going to further explain what 1.75 means and how it can help correct your vision. With this knowledge in mind, you can be more confident when you are shopping for prescription eyewear.

The Basics Around a 1.75 Eyewear Prescription

Looking at your eyewear prescription, you may see a collection of columns, rows, and cells. All of this data inherently provides detailed information about your sight and how prescription eyewear can help you see more clearly. For the purposes of this discussion, we are going to direct you to a column that is labeled “add.”

Add stands for addition. The basic idea is that this is the power that needs to be added in your prescription in order to give you a clear vision for certain activities. Often, these activities are for reading or other close-range activities, but they don’t have to be. If you are younger, you likely won’t see an add for your prescription, but this is a rule of thumb. There’s no need to worry if you do see it in your prescription. Another rule of thumb is that your add is the same for both eyes. While there are rare, there may be some exceptions.

Ultimately, a 1.75 add can be negative or positive. Let’s start with -1.75. A -1.75 eyewear prescription essentially signifies that you need some additional power to see some objects that are further away. Specifically, we are talking about things like watching television or objects or people at a distance when you are driving. Compared to a -1.25 eyewear prescription, for instance, a -1.75 eyewear prescription is going to be more powerful.

A +1.75 add will help you see more clearly when you are looking at close text or images. Near-point activities like reading are most common, but you can imagine other activities where you cannot see clearly at close range. A +1.75 add may indicate that you need some bifocal power in order to better focus on text that is close to you. You may be able to see +1.75 prescription glasses for sale if you are in your local pharmacy or drugstore, for instance. You will want to ensure that the rest of your prescription fits that particular pair of glasses, but it may be an option if you are interested.

A -1.75 and +1.75 prescription, as you can tell, presents a vast difference. And just to reiterate, this is just one element of your overall eyewear prescription. Therefore, you will definitely need to pay attention to the details when you are ordering your next pair of prescription glasses. While many websites (like Rx-Safety) let you upload an image of your actual prescription, you will want to be extra careful if you are manually inputting your prescription. Doing so will help you forego any issues or mistakes when ordering your new glasses.

      Hi Joseph,

      The +1.75 add helps you see more clearly when you are looking at close text or images. Your prescription is ok.

  2. Debra says:

    I need glasses for driving and TV. But my prescription says the sphere is +1.50. Could this be correct?

  3. Don Binns says:

    I’ve been given a new prescription noting both left and right lenses are the same SPH +2.5. Given my left eye is worse than my right I’m puzzled as to why it doesn’t require a different correction. Is this normal?

  4. Angie says:

    I have gone from R +2.00 Sph to +0.75 and L +1.50 to +0.50. My Cyl reading R -0.75 with no change and L -0.75 to -0.50. does this mean my eyes have improved??
