Doctors write "OD" on prescriptions with two primary meanings, depending on the context:
OD: “Once Daily”
When a doctor writes “OD” on a prescription, it means the medication should be taken once every day. This is often seen in treatments that require consistent, daily dosages to maintain effectiveness, such as antibiotics or medications for chronic conditions like hypertension or diabetes.
OD or o.d., an abbreviation used in medical prescriptions for omne in die or "once daily" both meaning "take once every day"
The abbreviation OD is frequently used in eye care and has two distinct meanings. When OD is part of your lens prescription, it is the abbreviation for the Latin term Ocular Dexter, which means “right eye.” When OD is written next to your eye doctor's name, it is the professional abbreviation for Doctor of Optometry.
In a typical prescription, two acronyms—one for each eye—are listed: O.D. This is short for oculus dexter, and is your right eye. O.S. This is short for oculus sinister, and is your left eye.
If there is a +2.50 on your prescription, this indicates that 2.5 diopters are needed to assist with farsightedness. The higher the number in this section, the more correction needed.
The sphere indicates the degree of nearsightedness or farsightedness, measured in diopters (D). A positive value, like +0.25, signifies mild farsightedness (hyperopia), while negative values indicate myopia.
The “highest” eye doctor—the type with the most extensive training—is an ophthalmologist, who must hold an MD degree before completing four years of additional ophthalmology schooling. Subspecialists in the field require still more education.
OS and OD meaning
OD is short for the Latin term oculus dexter which means right eye. OS is an abbreviation of the Latin oculus sinister which means left eye. You'll often see this terms on eyeglass prescriptions. The OU medical abbreviation is for oculus uterque in Latin which means both eyes.
The farther from zero, the stronger the prescription. A zero (or a "PL" or "Plane") means that no correction is necessary for that eye. Are you curious about what the diopter value on your prescription means? Myopia (-): 0.00 to -3.00 is mild, -3.00 to -6.00 is moderate and -6.00 or more is high.
Oppositional defiant disorder is a behavioral condition where a child or teenager is usually in an angry or cranky mood, defiant and combative to people in authority like parents and teachers.
• o.d. - can mean "once daily" or "right eye". • OJ - intended to mean "orange juice" but can be misread as "OD" or "OS"
An occupational disease (OD) is defined as: A wound or other condition of the body caused by a specific event or series of events or incidents over more than one work day or work shift.
Once Daily: OD can mean take once a day, from Latin omni die. It's often used in prescriptions, though many providers now prefer terms like QD (once daily), BID (twice daily), or TID (three times daily) to avoid confusion.
Bipolar Disorder (BD) Bipolar disorder is a common mood disorder that causes extreme shifts in mood, activity levels, and energy. There are three states that are typical of bipolar disorder: mania/hypomania (a 'high' state), depression (a 'low' state) and a normal state.
Od is commonly used as an abbreviation for 'overdose,' particularly in medical contexts, referring to an excessive and dangerous intake of substances.
A value up to 2.50 is considered moderate; anything above 2.50 may be considered severe. The third number (axis) reflects the orientation of your astigmatism. LASIK or PRK can treat the widest range of prescriptions from -14 through +6.
OD stands for “oculus dexter,” which means your right eye. OS stands for “oculus sinister,” which means your left eye.
Add stands for Addition. It stands for the additional correction that you need for reading. It is used in bifocal glasses, reading glasses, or varifocal glasses. It represents the additional power over the distance prescription.
Ophthalmologists must complete many more years of medical training than optometrists and opticians. As a result, an ophthalmologist is the most qualified among eye care professionals to diagnose and treat a wide range of eye diseases, beyond the routine eye and vision care provided by an optometrist.
No, a -7 prescription itself doesn't automatically mean someone is legally blind; legal blindness is defined by vision after correction, meaning 20/200 or worse in the better eye even with glasses or contacts, or a very narrow visual field (20 degrees or less), not just the number on the lens. While -7 is high myopia (nearsightedness) and indicates poor vision without correction, someone with -7 might achieve perfect 20/20 vision with glasses and therefore wouldn't be legally blind.

They use a definition for legal blindness set by the American Medical Association in 1934. According to that definition, “legally blind” means at least one of the following applies: You have 20/200 (or worse) eyesight, even with correction.

A Healthy Diet Protects Your Eyesight
Food provides nutrients that help to keep every part of your eye healthy. If your diet consists mostly of fried, fatty, processed, or sugary foods, your eyes may suffer, as a teenage boy in the United Kingdom discovered a few years ago.
