  4. The term sphere means that the correction for nearsightedness or farsightedness is spherical, or equal in all meridians of the eye. Cylinder (CYL) Cylinder indicates the amount of lens power needed for astigmatism. It always follows the sphere power on an eyeglass prescription
  5. CYL (Cylinder) CYL is a + or - value in 0.25 steps and is required to correct your astigmatism. If you have an astigmatism, you will find a + or - value in this box. You will also have a corresponding AXIS value (see below). When no astigmatism correction is required the optician will leave the box blank

  3. Cylinder (CYL) The cylinder number is how much astigmatism you have, if any. This is when part of the cornea has a different curve. Normally, an eye is shaped like a basketball—rotated any direction, the curve stays the same. An eye with astigmatism is more like a football—one curve is longer than the other
  4. 4. CYL & AXIS: a Cylinder (CYL) and Axis number (between 0 and 180 degrees) are required to correct Astigmatism. Both parameters will be required together. 5. ADD: provides magnifying power for reading, bifocal, multifocal and progressive lenses. You will most likely have the same number for both eyes that usually ranges between +0.75 and +3.00
  5. us cylinder notation. ADD is an abbreviation for Near Addition. This is the additional refractive power to be combined, or added, to the distance power to achieve the ideal near power
  6. If you do have a CYL number you will also have an axis number, based on a protractor scale that tells you where on the eye the astigmatism is found. For example, SPH -2.50 D CYL +5.00 Axis 40 means you have a nearsightedness of -2.50 dioptics with an astigmatism of +5.00 along the 40 degree axis

The axis value, always between 1 and 180 degrees, tells the lens maker where to place the astigmatism correction (the Cyl value). Prism and Base. If your eye muscles aren't working together as a team, we can use the prism and base values to correct them Corrected with -ve cylinder axis 180. In kids. Actually causes more defocus than ATR (lose more letters on eye chart). Can be + or minus 10 from 180. Defocuses horizonatal components of letters. ATR: the eye has more power HORIZONTALLY. Corrceted with -ve cyl axis 90. Causes least amount of letters lost on eye chart. Can be + or - 10 degres. The left eye (LE, or OS) is being prescribed -1.00 D sphere for myopia plus -0.50 D cylinder for the correction of astigmatism. The cyl power has its axis at the 180 meridian ( horizontal), meaning the 180 degree meridian of the eye has no added power for astigmatism and the vertical (90 degree) meridian gets the added -0.50 D Consequently, what is the normal eye SPH CYL and axis value? In reality, most normal eyes have about 0.50 diopters of negative cylinder power at axis 180 (horizontally), so a typical eye would have a prescription of plano (0.00 diopters sphere ) -0.50 x 180

Axis is measured in degrees, and refers to where on the cornea the astigmatism is located. Axis numbers go from 0 to 180. If you think of the eye as a map hanging on a wall, the 90 degree axis or line, runs up and down (or north to south.
  3. This eye needs a cylinder of -0.75 and an axis of 173 to correct astigmatism, and an ADD power of +2.25 to correct near vision. The ADD value is usually present in a multifocal prescription. The left eye is prescribed with a sphere of -3.00 to correct nearsighted
  4. What is Cyl in eye prescription? Cyl stands for Cylinder. This is your level of astigmatism (visual distortion), which is the amount of 'extra' prescription you have. Astigmatism is caused by an irregularly shaped cornea and can lead to blurred or distorted vision

This is a relatively low amount of nearsightedness. The second column denotes -1.00 diopters of astigmatism, and this person will need a 100-degree axis to correct the issue The 'CYLINDER' is the number that describes the amount of astigmatism that the eye has. Astigmatism is a measure of the curvature of the eye. The 'AXIS' is related to the cylinder curvature and shows the direction of where the eye is curved. These measurements are your eyeglass prescription numbers and are used to make glasses Spherical equivalents are often used by eye doctors to prescribe contact lenses for patients with low astigmatism or patients who want colored contact lenses (very few colored contact lens brands are able to correct astigmatism), to reduce the astigmatism in an eyeglass prescription for patients who have trouble adapting, or to compare overall.

Meridians of the eye are determined by superimposing a protractor scale on the eye's front surface. The 90-degree meridian is the vertical meridian of the eye, and the 180-degree meridian is the horizontal meridian.
