What does 0.00 sphere mean?

It is measured in diopters and suggests that you need a spherical correction for your sight. An SPH number indicates if you are farsighted or nearsighted. If the SPH value is 0.00, or noted by Plano, Pl, or an infinity sign, you do not have a vision distance problem.

What does 0.00 mean for glasses?

On a glasses prescription, 0.00 (zero focusing power needed) represents good vision. Generally, the further away from zero you go (whether the number is positive or negative), the worse your eyesight and the greater the need for vision correction.

What is a normal eye sphere number?

What is the normal eye SPH, CYL, and Axis value? Normal eyes would typically have about 0.50 dioptres of negative cylinder or cyl power at an axis number of 180. Typically, most people have between 0.5 to 0.75 dioptres of astigmatism and won't need contact lenses or glasses to see clearly.

What does 0.00 cyl mean?

CYL. The abbreviation stands for Cylinder. It represents the amount of lens power you need for astigmatism. If you do not have astigmatism, you may not have anything indicated in this column. The value may be a plus or a minus, and in most cases, the value will be between +/-0.25 to +/-4.00.

Are 0.00 contacts non prescription?

You still need a prescription.

Even if your colored contacts have zero power, you do still need to see a doc. That's because all contacts, clear or color, are serious medical devices that can potentially damage your eyes. Plus, it's the law!

WHAT DOES MY EYEGLASS PRESCRIPTION MEAN

What does 0.0 Plano mean for contacts?

If there is "Plano" or "PL" in the SPH section of your prescription, it means no nearsighted or farsighted correction is needed. Enter 0 for your value wizard.

What does 0.00 Plano mean for colored contacts?

Plano lenses are simply an optical lens which provide no corrective power. You'll know if you require plano lenses if you see the term “plano”, “PL” or “0.00” in your Sphere box on your prescription paper.

What is the sphere on eye test results?

Sphere (SPH) – The term “sphere” means that the correction for nearsightedness or farsightedness is spherical, equal in all meridians of the eye. This indicates the amount of lens power, measured in diopters (D), prescribed to correct nearsightedness or farsightedness.

What does sphere mean on eye exam?

The term “sphere” means that the correction for nearsightedness or farsightedness is spherical, meaning equal in all meridians of the eye.

What does +0.50 mean for vision?

OS +.50. Refractive Power – The first number in the series identifies your degree of nearsightedness or farsightedness. A plus sign (+) indicates you are farsighted, a minus sign (-) indicates you are nearsighted.

What is a bad eye sphere number?

-3.00 diopters or less is mild. -3.00 to -6.00 diopters is moderate. -6.00 to -9.00 diopters is severe. -9.00 diopters or more is extreme.

What sphere is considered blind?

Most health institutions and government agencies agree that if the vision in your best eye is 20/200 with correction, then you are legally blind.

What is normal sphere range?

Typical SPH numbers range between 0.00 and +/- 20.00. The SPH number on a glasses prescription is listed as a positive (+) or negative (-) number. A negative number means that the lens is correcting for nearsightedness, while a positive number indicates a prescription for farsightedness.

How strong is 0.0 for reading glasses?

A: 0.00x means that there is no magnification....they are plain glass lenses. if you hit the down arrow where you see that, it will show different reading strengths (1.25, 1.50 etc) v:) Helpful?

What is a bad astigmatism number?

Between . 75 and 2 diopters is considered mild astigmatism. Between 2 and 4 diopters is moderate astigmatism, and 4 or more diopters is considered significant or “bad” astigmatism. Generally, eyes with 1.5 diopters of astigmatism or more require correction.

What is the lowest eye grade?

The lowest strength is usually 1.00 diopters. Glasses go up in strength by factors of . 25 (1.50, 1.75, 2.00). The strongest glasses are 4.00 diopters.

Is sphere the same as astigmatism?

'Sphere' is basically a measure of how strong your prescription needs to be. The number marked 'axis' describes the orientation of astigmatism. It will be a number between 1 and 180. The number under 'cylinder' provides the lens power needed to correct the astigmatism.

What does sphere 0.25 mean?

If this box is empty, it means that there is no astigmatism and your eyes are perfectly spherical. A low number like 0.25 means your eyes are not quite round and a higher number like 3.00 means your eyes are quite oval.

Does sphere mean astigmatism?

SPH, or sphere, is the amount of lens power needed to correct nearsightedness or farsightedness, whereas CYL, or cylinder, is the amount of lens power needed to correct astigmatism. When people talk about their eye degree or “power,” they are usually referring to their SPH value.

How do I read my eye test results?

In general, the further away from zero the number on your prescription, the worse your eyesight and the more vision correction (stronger prescription) you need. A “plus” (+) sign in front of the number means you are farsighted, and a “minus” (-) sign means you are nearsighted.

What is good numbers for eye exam?

Having 20/20 vision means that your vision is normal. If you don't have 20/20 vision, your eye care professional will help you find out what condition may be affecting your vision. They'll also help you find a way to improve your vision, such as wearing glasses or having eye surgery.

What does a positive sphere mean?

If the sphere indicates "Pl" or "Plano" for both eyes, it means that you do not suffer from myopia or hyperopia. A positive sphere indicates hyperopia. People affected by farsightedness have either an eyeball that is too short, or a retina curvature of that is not pronounced enough.

What are positive and negative SPH values?

SPH stands for spherical power and describes the degree of nearsightedness or farsightedness. A positive value, or a prescription with a plus-sign (+), means that your child is farsighted. If you see a negative value (-) that means your child is nearsighted.

What is 0.0 diopter?

Astigmatism is measured in diopters. A perfect eye with no astigmatism has 0 diopters.

What does sphere number mean?

Sphere. This number determines the lens power needed to provide clear vision for each eye. A minus sign before the number indicates that you are nearsighted, while a plus sign means that you're farsighted. Lens power is measured in diopters. The higher the number, the stronger the prescription.
