Worry not! In this simple guide, we\u2019ll unlock the meanings behind the abbreviations OD and OS, helping you understand your vision needs better. It\u2019s crucial to know these details when ordering <a href=\"\/\" target=\"_blank\" rel=\"noopener noreferrer\" aria-label=\"Visit eyeglasses Page (opens in new tab)\"><strong>eyeglasses<\/strong><\/a> online to ensure that your new specs will help you see clearly and comfortably.<\/p>\n<h2><strong>Understanding OD and OS<\/strong><\/h2>\n<p><strong><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-75144\" src=\"https:\/\/www.zennioptical.com\/blog\/wp-content\/uploads\/2023\/12\/OD-OS_2.jpg\" alt=\"\" width=\"916\" height=\"500\"><\/strong><\/p>\n<p>The terms OD and OS are short for the Latin phrases \u201coculus dexter\u201d and \u201coculus sinister,\u201d which translate to \u201cright eye\u201d and \u201cleft eye,\u201d respectively. When you see OD and OS on your prescription, they\u2019re simply indicating the vision correction for each eye. Here\u2019s a breakdown of what you might find next to these abbreviations:<\/p>\n<ul>\n<li><strong>Sphere (SPH):<\/strong> This number shows the level of lens power, measured in diopters, needed to correct your vision. A negative value indicates myopia (nearsightedness), and a positive value suggests hyperopia (farsightedness).<\/li>\n<li><strong>Cylinder (CYL) &amp; Axis:<\/strong> These values are related to astigmatism. The CYL number represents the lens power for astigmatism, and the Axis denotes its orientation.<\/li>\n<li><strong>Add:<\/strong> This number is relevant for those who need <a href=\"\/progressive-lenses\" target=\"_blank\" rel=\"noopener noreferrer\" aria-label=\"Visit progressive lenses Page (opens in new tab)\"><strong>progressive lenses<\/strong><\/a> or bifocals, signifying the added magnifying power for reading.<\/li>\n<li><strong>Prism:<\/strong> This indicates the need for prismatic power to correct eye alignment issues, measured in prism diopters.<\/li>\n<\/ul>\n<p>By familiarizing yourself with these terms, you gain a clearer understanding of your visual health and keep informed on what your eyes require.<\/p>\n<h2><strong>Measuring Pupillary Distance<\/strong><\/h2>\n<p>Another vital piece of information is your <strong>pupillary distance<\/strong> (PD), the space between the centers of your pupils. This measurement ensures that the lenses are positioned correctly in the frames. If you\u2019re unsure of your PD, you can easily measure it at home or visit an eye care professional.
