Refers to the amount of extra power needed to correct the astigmatism. It will always appear as a - (minus) number.
Indicates the area of the extra power in a toric lens. This oval area could be vertical or horizontal or at any angle in between; with an axis between 0 and 180 degrees.

 Is there a difference between toric lenses and lenses for astigmatism?

No, the toric shape purely describes the shape of the lens that is suitable to correct astigmatism.

What is the meaning of Astigmatism?

Astigmatism is one of the most common refractive errors. Similar to other body parts like ears, legs or feet, the clear surface which is called cornea of the eyeball is not 100% symmetrical but slightly shaped similar to a rugby ball (toric in shape) or in some cases has an irregular shape in general from birth or after an injury. Simply put, the need for correction is for some areas of the eye stronger than for the rest of the eye.

Astigmatism Meaning

How common is Astigmatism in UAE, Saudi, Kuwait, Qatar, Oman and Bahrain?

According to several studies conducted on several continents, astigmatism exists in most parts of the populations and is not limited to a particular continent. Therefore, it is safe to assume that astigmatism is as common in the GCC / Middle East as in any other country in the world.

What is Cylinder and Axis in toric contact lenses for astigmatism?

A contact lens prescription for the correction of nearsigthed astigmatism, for example, could be: -2.50 -1.00 x 90.

  1. The first number (-2.50) stands for the Sphere power for the correction of myopia in the flatter (less nearsighted) part of the eye.
  2. The second number (-1.00) stands for the Cylinder power of the additional myopia (nearsightedness) correction required for the more curved part of the eye. In this case, the total correction required for this area (also called meridian) is -3.50 D (-2.50 + -1.00 = -3.50 D)
  3. The third number (90) is called the Axis. This is the location (in degrees) of the flatter area of the eye, on a 180-degree scale where 90 degrees designates the vertical axis of the eye, and 180 degrees designates the horizontal axis.
