Purchasing a pair of eyewear online is increasingly becoming the new trend. Online eyeglass stores, such as NURILENS, offer a number of vision options from standard single vision lenses to premium progressive lenses. The experience, however, can switch from convenient to stressful when it comes to answering questions about your prescription. Your prescription specifies a unique set of mathematical requirements that enable you to vividly capture the beauty of everything around you. Understanding your vision you have and what the different values on your prescription mean can surely be confusing.
Here are some of the things you want to look out for when reading your prescription.
These values represent various precise measurements that help you obtain your optimal vision. They measure the required lens power that are attributed to correct nearsightedness, farsightedness, and astigmatisms.
OD and OS are extremely popular terms in the optical world. They are Latin abbreviations that refer to your right and left eye. OD is the abbreviation for ‘oculus dexter’ which translates to ‘right eye’. OS is the abbreviation for ‘oculus sinister’ which translates to “left eye”.
While choosing between single vision lenses vs. progressive lenses, remember:
As time passes, your vision is likely to change, so it is good to keep in touch with your optometrist every year or two, so that you always have an up-to-date prescription.
An add value refers to the added magnifying strength needed to help someone see something up close. These values allow you to get progressive or multifocal lenses that have corrections to fix your distant vision (upper portion of the lens), along with adjustments to see things up close (bottom portion of lens).
If your optician or optometrist has ever held up a ruler of some sort to your eyes, they are probably measuring your pupillary distance. Abbreviated to PD, your pupillary distance is a measurement of the distance between the centers of your pupils.
Your PD might come in one value or two. If your PD is divided between your right and left eye, then each value is a measurement from the center of your pupil to the center of the bridge of your nose.
Your PD is an important value as it allows your glasses to be properly measured for the center of your vision. While there are tools online to help you measure your PD on your own, it’s always best to have an optical professional measure it for accuracy. As compared to the other values on your prescription, your PD is least likely to change from year-to-year. Nevertheless, it’s always good to verify it to ensure an accurate prescription.
