Seeing ‘Plano’ on Your Prescription? Here’s The Truth
Have you ever wondered why there is a prescription on your eyeglasses that the word ‘Plano’ is printed with one of your eyes? You’re not alone!
The first impression that I got when I saw Plano on my own prescription was that something was amiss or missing. However, in fact, it is entirely normal—and knowing this can tell you a great deal about your eyesight.
In this blog, I’ll explain in simple terms what “Plano” means, why it appears on your prescription, and how it affects your glasses or contact lenses.
What Does “Plano” Mean on an Eye Prescription?
The word Plano (pronounced PLAY-no) simply means “no correction needed.”
This is to say, when your prescription includes Plano in one or both eyes, then this means that your eyesight does not have any power to correct either nearsightedness (myopia) or farsightedness (hyperopia).
You may have other reasons to wear lenses, such as astigmatism or protection; however, your primary vision prescription is 0.00, and this is the meaning of the term Plano.
Plano = Zero Lens Power
In optical terms, “Plano” equals 0.00 diopters, meaning your eye’s focus is naturally good at distance without corrective power.
Your prescription would therefore be as follows:
| Sphere (SPH) | Cylinder (CYL) | Axis |
|---|---|---|
| Plano | -0.75 | 90° |
In this example, your sphere (which corrects nearsightedness or farsightedness) is Plano — no correction needed — but you still have astigmatism correction.
Plano in Different Prescription Formats
Plano will be written in various forms in your prescription, depending on the eye doctor or optic store. Here are common formats:
- PL – short for Plano
- 0.00 – numerical representation
- Infinity (∞) – rare, but used in some optical systems
Why One Eye Might Be Plano (and the Other Isn’t)
Most individuals have one eye with better strength than the other; thus, you may end up having Plano on one side only.
For example:
| Eye | SPH | CYL | AXIS |
|---|---|---|---|
| Right (OD) | Plano | -0.50 | 80° |
| Left (OS) | -1.75 | -0.25 | 100° |
It is as though your right eye will not require distance correction, but your left eye is a little short-sighted.
What Are Plano Glasses?
Another common usage of the word is in the purchase of the so-called Plano lenses or non-prescription glasses.
Plano glasses contain no optical power whatsoever; that is, there are flat lenses designed to be used:
- Blue light protection
- UV blocking
- Fashion or aesthetic use
- Safety glasses

Plano Contact Lenses: Are They the Same?
Yes — Plano contact lenses are non-corrective lenses too.
These are typically used for:
- Cosmetic color lenses (for changing your eye color)
- Special effect glasses (such as Halloween glasses)
- Protective or medical uses
Plano in Sphere Section (SPH)
If you see Plano under the Sphere (SPH) section, it specifically means:
Your eye doesn’t have nearsightedness or farsightedness.
It is the SPH column that defines the necessity of the need of your eyes to see distant or nearby objects.
- Negative numbers (like -2.00) = nearsighted
- Positive numbers (e.g., +1.75) = short-sighted.
- Plano (0.00) = normal focusing power
Plano Vision vs. Normal Vision
Consider Plano vision as possessing a balanced vision – you will have sight without the aid of optical vision to see farther.
But that does not necessarily imply that you have flawless eyes. You might still:
- Struggle with close-up tasks (especially after 40, due to presbyopia)
- Experience digital eye strain
- Have slight astigmatism or focus imbalance
Quick Summary Table: What Plano Means in Eye Prescriptions
| Term | Meaning | Lens Power | Common Use |
|---|---|---|---|
| Plano | No correction needed | 0.00 | Normal vision |
| Plano Glasses | Non-prescription lenses | 0.00 | Fashion / Protection |
| Plano Contacts | Non-corrective lenses | 0.00 | Cosmetic or medical use |
| Plano Sphere | No distance correction | 0.00 | May still have astigmatism |
FAQs
What does Plano mean on an eye prescription?
Plano implies that you do not require any correction of your vision level; your diopters are 0.00 (there is no short or long-sightedness).
Is Plano vision good?
Yes! Plano vision implies that your eyesight is clear as you see things at a distance. It is an indicator of good, balanced vision, although you can still wear glasses to protect your eyes or as a comfort with the screen.
Does Plano mean 20/20 vision?
Not always. Plano indicates no correction is needed, but 20/20 vision measures visual clarity. You can have Plano and still not see exactly 20/20 — or vice versa.
What does “Plano” (PL) mean in an eye prescription?
“PL” or “Plano” means zero power in your lenses. It’s often used interchangeably with 0.00 on your eye prescription chart.
What does 0.00 Plano mean for glasses?
It is used to refer to a pair of glasses that lacks the power of a prescription (most of the time, blue lights or UV protection, or style).

Final Thoughts
When you are told that your prescription is Plano, it only means that you do not have to be corrected with the help of vision aid because your eyesight is balanced.
Nevertheless, despite the Plano vision, regular eye checkups and the use of blue light or UV protection glasses are also worth your attention, particularly when you spend most of your time on the screen.
