Your prescription, in plain language

Right eye (OD)

You are mildly nearsighted (-2.75 diopters). Without correction, near objects are sharp but distance — road signs, a presentation screen — turns blurry.

You also have very mild astigmatism (-0.75, axis 175°): your cornea isn't perfectly round, so the image distorts in one direction. Very common — and very correctable.

Left eye (OS)

You are mildly nearsighted (-2.50 diopters). Without correction, near objects are sharp but distance — road signs, a presentation screen — turns blurry.

Good to know: This explanation is educational and doesn't replace an eye exam. A prescription describes lens power, not eye health — that requires an examination.

Frequently asked questions

Is minus 2 a bad prescription?

Around −2 is a common, mild-to-moderate myopia: distance is blurry without glasses, near is often fine. It isn't 'bad' — and it says nothing about the health of your eyes, only about their focus.

What is the difference between SPH and CYL?

SPH (sphere) corrects near- or far-sightedness in all directions; CYL (cylinder) corrects astigmatism in one specific direction, indicated by AXIS.

Can I order glasses myself with this prescription?

A prescription is a snapshot, and glasses involve more than lenses: fit, pupillary distance and lens choice matter. An optician remains the best route — certainly with higher powers or cylinders.

Keratoconus thins and steepens the cornea, often from the teenage years. Why an ever-changing cylinder is a signal, and how cross-linking can halt the disease.
