Your right eye RX (OD) is very weak. Your left eye RX (OS) is rather mild. -US Navy Optician
"od" on a prescription for eye drops mean "right eye"--as in apply the drops to the right eye. "os" means "left eye".
In eye prescriptions, "OS" refers to the left eye and "OD" refers to the right eye.
"OD" in an eye prescription stands for "oculus dexter," which means right eye in Latin. It indicates the specific correction needed for the right eye. The prescription for the left eye is labeled as "OS" for "oculus sinister." Understanding these labels helps ensure the correct lenses are prescribed and fitted for each eye, leading to accurate vision correction.
OD = right eye, OS = left eye. It's latin based OD = ocula diestra, OS = ocula siniestra, OU = oculi uniti (both eyes)
A prescription would be needed to determined the 'power' of each eye if you're ordering contacts. If you're unsure and/to unable to get an eye exam to determine your prescription, to be on the safe side order +0.00 OS and +0.00 OD.
The O.D. designation on an eyeglass or contact lens prescription means the right eye or oculus dexter. The O.S. means left eye or oculus sinister.
Right OS = Left Yes....from oculus (eye) dexter (right) and oculus sinister(left)
In science, OD typically stands for "optical density," which is a measure of how much light is absorbed or scattered by a substance. It is commonly used in spectrophotometry to quantify the concentration of a substance in a solution.
Od means RIGHT eye,and 50 x 100,it's result OS means LEFT eye,and 50x 95,it's result.
The terms Oculus Dexter (right eye), Oculus Sinister (left eye), and Oculus Uterque (both eyes) are used in medicine, usually abbreviated OD, OS, and OU, respectively.
Your ophthalmologist, optometrist, or optician should explain that to you . . . whoever it was that wrote the prescription.
