Confusingly, the chart incorporates a mix of letter abbreviations, positive and\/or negative numbers, and full words.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What do they all mean? Consult our glossary below to tackle each element, then take a look at our example eye prescription chart to apply your knowledge.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"eye-prescription-abbreviations\">Eye Prescription Abbreviations<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>OD: <\/strong>Your right eye. OD stands for <em>oculus dexter<\/em>, which is \u201cright eye\u201d in Latin. We get the words dextrous and dexterity from the same root!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>OS: <\/strong>Your left eye. OS stands for <em>oculus sinister<\/em>, which is \u201cleft eye\u201d in Latin. We promise there\u2019s nothing more morally sinister about <a href=\"\/learn\/od-vs-os\">your left eye than your right<\/a>\u2014in this case, the word is merely referring to direction.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>OU: <\/strong>Both of your eyes. OU stands for <em>oculus uterque<\/em>, which is \u201cboth eyes\u201d in Latin.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>NV: <\/strong>Near vision (seeing things close-up).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>DV: <\/strong>Distance vision (seeing things far away).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PD: <\/strong>Pupillary distance. Your pupillary distance is\u2014drumroll\u2014the <a href=\"\/learn\/pupillary-distance\">distance between your pupils<\/a>! It\u2019s a handy measurement that helps align the center of the lens with the center of your pupils so that you have the most accurate vision possible. Your pupillary distance can be measured in a number of ways, including manually or with a specialized device called a pupillometer.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In an ideal world, your eye doctor will include your PD on your prescription every time. But not all doctors do this. If yours doesn\u2019t, you can always use our handy tool to <a href=\"https:\/\/www.warbyparker.com\/pd\/instructions\">measure your pupillary distance online<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SPH: <\/strong>Sphere. In this case, \u201csphere\u201d means that the correction for nearsightedness or farsightedness is spherical\u2014as in, equal in all meridians of the eye. You\u2019ll see numbers listed in the SPH column, and we\u2019ll get to those next\u2026&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"eye-prescription-scale\">Eye Prescription Scale<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Diopters<\/strong>: Any numbers you see in the \u201cSphere\u201d or \u201cCyl\u201d column of your eye prescription stand for <a href=\"https:\/\/www.warbyparker.com\/learn\/what-is-a-diopter\">diopters<\/a>. A diopter is a unit of measurement, like a gram or an ounce. Instead of measuring mass, however, diopters measure the refractive power of a lens. You\u2019ll see larger numbers (more optical power!) if your prescription is higher and lower numbers if your vision doesn\u2019t need as much help from glasses or contacts.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s important to note that these numbers proceed in either direction on a number line\u2014they can be positive or negative, based on the type of refractive error in your eye. If you don\u2019t need glasses at all, you wouldn\u2019t need any optical power from lenses: 0 diopters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Negative Numbers: <\/strong>If you see a minus sign in front of a number, that indicates nearsightedness, or <a href=\"\/learn\/what-is-myopia\">myopia<\/a>. Someone with -3 diopters of nearsightedness, for example, might have trouble reading words on a chalkboard from far away.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Positive Numbers: <\/strong>If you see a plus sign in front of a number, that indicates diopters that will correct <a href=\"https:\/\/www.warbyparker.com\/learn\/what-is-farsightedness\">farsightedness, or hyperopia<\/a>. Someone with +3 diopters of farsightedness, for example, might struggle to read text that\u2019s very close to their face.&nbsp;<\/p>\n\n\n\n\n\n<h3 class=\"wp-block-heading\" id=\"other-terms-on-your-eye-prescription\">Other Terms on Your Eye Prescription<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the kinds of lenses you need, you may see other terms on your eye prescription, including:&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>CYL or Cylinder:<\/strong> This term is only relevant to people with astigmatism, and refers to the lens power needed to address it. <a href=\"\/learn\/what-is-astigmatism\">Astigmatism<\/a> means your eye\u2019s cornea or lens is not completely spherical. Therefore, patients with astigmatism need cylindrical rather than spherical vision correction. (If there\u2019s no number associated with this term on your prescription, then you have no astigmatism to correct!)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Axis:<\/strong> Again, this is for people with astigmatism. It\u2019s the number (from 1 to 180) on your prescription that determines the orientation of your astigmatism correction. Axis is measured in degrees, not diopters. The cylinder and the axis always go together\u2014you can\u2019t have one without the other!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Add:<\/strong> Additional magnification. If you have age-related <a href=\"https:\/\/www.warbyparker.com\/learn\/what-is-presbyopia\">presbyopia<\/a>, you may have difficulty reading text close up, and can reserve a section of your glasses lenses for some added magnifying power. It\u2019s sort of like having reading glasses built into your regular ones.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Prism:<\/strong> Sometimes, eyes don\u2019t move in alignment with one another, resulting in symptoms such as double vision. (One disorder that causes eye misalignment is strabismus, commonly known as \u201ccrossed eyes.\u201d)&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To account for this condition, your doctor can <a href=\"\/learn\/what-are-prism-glasses\">add a prism to your lenses<\/a>. The prism is placed in a certain position and orientation based on your prescription, which will also notate the direction of the prism\u2019s thickest edge, or base.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>BU: base up<\/li>\n\n\n\n<li>BD: base down<\/li>\n\n\n\n<li>BI: base in<\/li>\n\n\n\n<li>BO: base out<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The prism will also have its own refractive strength, measured in prism diopters.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Expiration Date: <\/strong>Your eye prescription probably won\u2019t be the same forever\u2014it\u2019s important to <a href=\"https:\/\/www.warbyparker.com\/learn\/how-often-should-you-get-an-eye-exam\">have your eyes examined regularly<\/a> to make sure they\u2019re seeing as best as they possibly can.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eye prescriptions are normally valid for a year or two before they <a href=\"\/learn\/how-long-do-glasses-prescriptions-last\">expire<\/a> (the exact time period can vary depending on state laws). After that, you\u2019ll need to renew it by scheduling an eye exam.<\/p>\n\n\n\n<\/div><!-- .entry-content (split for inline block) -->\n\n<section class=\"wp-blocks__banner has-img white\">\n\t\t\t<div>\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.warbyparker.com\/learn\/wp-content\/uploads\/2022\/02\/virtual-vision-test-cta.jpg\" alt=\"Prescription Expired?\" loading=\"lazy\" \/>\n\t\t<\/div>\n\t\t<div class=\"wp-blocks__banner-img\">\n\t\t\t\t\t<h2>Prescription Expired?<\/h2>\n\t\t\t\t<p>If you\u2019re still seeing clearly, you can renew your prescription from home for just $15<\/p>\n\t\t\t\t\t<div class=\"wp-blocks-banner__cta-links\" style=\"flex-wrap:wrap;\">\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.warbyparker.com\/virtual-vision-test\">Take our Virtual Vision Test <svg id=\"aa495747-7767-4ea8-bc8e-3e09f9e2a480\" data-name=\"Layer 1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 5.5 9.5\"><path d=\"M5.49,4.61a.87.87,0,0,1,0,.32.73.73,0,0,1-.2.35l-4,4A.75.75,0,0,1,.22,8.22L3.69,4.75.22,1.28A.75.75,0,0,1,1.28.22l4,4A.75.75,0,0,1,5.49,4.61Z\" style=\"fill:#1050D0;fill-rule:evenodd\"\/><\/svg>\n<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n<\/section>\n\n<div class=\"entry-content\"><!-- (reopen for inline block) -->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"eye-prescription-chart-example\">Eye Prescription Chart Example<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are two examples of eye prescriptions, one for someone without astigmatism, and one for someone with it. Can you spot the differences and decode the terms you\u2019ve learned? If so, you\u2019ve learned how to read a glasses prescription like a pro.&nbsp;<\/p>\n\n\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"is-your-eye-prescription-bad\">Is Your Eye Prescription \u201cBad\u201d?&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We get asked this question all the time: \u201cHow bad is my eye prescription?\u201d But we don\u2019t go in for that kind of negative self-talk! There\u2019s no such thing as a \u201cbad\u201d eye prescription\u2014you likely mean that you\u2019re worried your prescription is unusually strong.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019re interested in cutoffs between moderate and severe kinds of vision issues, we can tell you that nearsightedness needing a refractive correction of -5 diopters or more <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6688422\/\" target=\"_blank\" rel=\"noreferrer noopener\">is often considered \u201chigh myopia,\u201d<\/a> whereas a prescription reading +5.25 diopters <a href=\"https:\/\/eyewiki.aao.org\/Hyperopia#cite_ref-prima_1-0\" target=\"_blank\" rel=\"noreferrer noopener\">fits the bill for \u201chigh hyperopia.\u201d<\/a> However, these scales can vary from institution to institution.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another fun fact: people with severe nearsightedness can experience issues with their near vision in addition to their distance vision, and people with severe farsightedness can have their distance vision affected, too. Vision correction is complex!&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most important takeaway is that your eyesight isn\u2019t \u201cgood\u201d or \u201cbad\u201d\u2014it just needs a specific amount of stylish tech to be as sharp as you want it to be.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"will-your-eye-prescription-change\">Will Your Eye Prescription Change?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Large fluctuations in your vision prescription over time aren\u2019t normal and should be investigated (unless they\u2019re the anticipated result of a treatment or injury). But small, gradual changes can certainly occur, especially as you and your eyes age.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, you can expect to develop presbyopia as you get older (it typically happens to most of us in our forties). When that happens, you might want to get a pair of <a href=\"https:\/\/www.warbyparker.com\/eyeglasses\/reading\">reading glasses<\/a> or incorporate new <a href=\"https:\/\/www.warbyparker.com\/progressives\">progressive lenses<\/a> into your regular frames.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even if you don\u2019t think your vision is any different and you\u2019re not experiencing any worrisome symptoms, it\u2019s a good idea to get your eyes checked every year. Annual <a href=\"https:\/\/www.warbyparker.com\/learn\/what-to-expect-at-an-eye-exam\">eye exams<\/a> ensure that an optometrist is monitoring your eye health and updating your prescription as needed.&nbsp;<\/p>\n\n\n\n<\/div><!-- .entry-content (split for inline block) -->\n\n<section class=\"wp-blocks__banner has-img white\">\n\t\t\t<div>\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.warbyparker.com\/learn\/wp-content\/uploads\/2022\/02\/phoropter-cta.jpg\" alt=\"Due for a check-up?\" loading=\"lazy\" \/>\n\t\t<\/div>\n\t\t<div class=\"wp-blocks__banner-img\">\n\t\t\t\t\t<h2>Due for a check-up?<\/h2>\n\t\t\t\t<p>Swing by your nearby store for an annual eye exam<\/p>\n\t\t\t\t\t<div class=\"wp-blocks-banner__cta-links\" style=\"flex-wrap:wrap;\">\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.warbyparker.com\/appointments\/eye-exams\/booking\">Book an eye exam <svg id=\"aa495747-7767-4ea8-bc8e-3e09f9e2a480\" data-name=\"Layer 1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 5.5 9.5\"><path d=\"M5.49,4.61a.87.87,0,0,1,0,.32.73.73,0,0,1-.2.35l-4,4A.75.75,0,0,1,.22,8.22L3.69,4.75.22,1.28A.75.75,0,0,1,1.28.22l4,4A.75.75,0,0,1,5.49,4.61Z\" style=\"fill:#1050D0;fill-rule:evenodd\"\/><\/svg>\n<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n<\/section>\n\n<div class=\"entry-content\"><!-- (reopen for inline block) -->\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-about-contact-lens-prescriptions\">What About Contact Lens Prescriptions?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You might be wondering: Is my contact lens prescription the same as my glasses prescription?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not always! Your glasses sit at a slight distance away from your eyes, whereas <a href=\"https:\/\/www.warbyparker.com\/contacts\">contact lenses<\/a> rest directly on your corneas. That difference in distance means their prescriptions might not match up.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, because contact lenses come with fixed parameters determined by their manufacturers, the doctor may need to adjust your <a href=\"\/learn\/how-to-read-contact-prescription\">contact prescription<\/a> accordingly. These adjustments can also differentiate your contact prescription from your glasses prescription.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even if the values on your contact lens and glasses prescription are the same, your contact prescription needs to include the name of the brand you&#8217;ve been prescribed (e.g. <a href=\"https:\/\/www.warbyparker.com\/contacts\/acuvue\">Acuvue<\/a>, <a href=\"https:\/\/www.warbyparker.com\/contacts\/clariti\">clariti<\/a>, <a href=\"https:\/\/www.warbyparker.com\/contacts\/dailies\">DAILIES<\/a>, etc.).  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your optometrist <em>also<\/em> needs to put additional information on your contact lens prescription related to fit. That\u2019s right\u2014your contacts need to fit you, just like anything else you wear.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The two measurements you should also see on your contact lens prescription are:&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Base Curve (BC): <\/strong>The curvature of your contact lens, which should mold comfortably to the curvature of your natural eye. This measurement in millimeters (mm) always falls between the numbers 8 and 10.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Diameter (Dia)<\/strong>: Just like in regular math, the diameter is the width of a contact lens in millimeters. Most contact lenses are between 13 and 15 mm wide.<\/p>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">Without all of the information above, you won&#8217;t be able to purchase contact lenses. Submitting your glasses prescription alone won&#8217;t cut it! So, if you want to wear contacts in addition to (or instead of) glasses, be sure to let your eye doctor know when you schedule your exam. That way, they\u2019ll know to include a contact lens fitting to assess the fit and vision of the contacts.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"remember-you-have-a-right-to-your-eye-prescription\">Remember: You Have a Right to Your Eye Prescription<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">According to the <a href=\"https:\/\/www.consumer.ftc.gov\/articles\/buying-prescription-glasses-or-contact-lenses-your-rights\" target=\"_blank\" rel=\"noreferrer noopener\">Federal Trade Commission<\/a>, you are legally entitled to a copy of your eye prescription. Your eye doctor should provide you with one after your exam, or whenever you request it.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You don\u2019t have to purchase eyewear from their office to get your eye prescription, and you should never have to pay a fee solely to access it.
