Understanding the Basics of Your Prescription

Your eye exam prescription is key to knowing how to fix your vision. It’s filled with abbreviations and numbers that tell you what you need. Each part of your prescription is important for your vision correction.

Decoding Abbreviations: OD, OS, and OU

First, learn the eye abbreviations. OD means Oculus Dexter, or “right eye.” OS is Oculus Sinister, or “left eye.” OU (Oculus Uterque) means both eyes.

Knowing these abbreviations is key. Your prescription will list each eye’s needs separately. This is because each eye might need different corrections.

Breaking Down the Numbers: SPH, CYL, and Axis

Your prescription has numbers for different vision corrections. The main parts are SPH (Sphere), CYL (Cylinder), and Axis.

• SPH shows the lens power for nearsightedness or farsightedness, in diopters (D).
• CYL is for astigmatism correction, also in diopters.
• Axis tells where the astigmatism correction goes, in degrees.

For instance, a SPH of -2.00 for your right eye (OD) means you’re nearsighted by 2 diopters. If the CYL is -1.00 with an Axis of 90 degrees, it means you have astigmatism. The Axis tells where the corrective lens should go.

Eye exam results give you important info about your vision and eye health. Learning to understand them is key to caring for your eyes. When you get your results, you’ll know more about your eye health and what corrections you might need.

Identifying Refractive Errors

Refractive errors happen when your eye doesn’t bend light right, causing blurry vision. Common ones are myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Your exam results will show if you have any and how severe they are.

Myopia shows as a minus (-) in your prescription, meaning you see near things better. Hyperopia has a plus (+) sign, showing you see far things better. Astigmatism is shown by a cylindrical (CYL) value and an axis number, which tells where the astigmatism is.

Reading Visual Acuity Scores

Visual acuity numbers show how well you can see at different distances. The 20/20 score is normal vision. For example, a 20/40 score means you see things at 20 feet that a normal person sees at 40 feet.

Knowing your visual acuity score helps you understand your vision problems. A score of 20/200 or worse in both eyes is legal blindness. Regular eye exams help track any changes in your vision.

Recognizing Notes on Eye Health and Pressure

Intraocular pressure (IOP) is key for spotting eye conditions like glaucoma. Your doctor uses a tonometer to measure IOP in millimeters of mercury (mmHg). Normal IOP is between 10-21 mmHg, but it can vary.

Your eye health notes might talk about your retina, cornea, and other parts of your eye. Any issues or concerns are usually noted, along with advice for more tests or treatment if needed.
