Thank you for asking at HealthReplies.com.
Diopters are the strength of the lens that is used to help correct visual disturbances. The diopters value is found from the formula d = 1000 / focal length (in mm). Thus, the calculation of diopters is obtained after knowing the focal length of your eye's vision from the examination conducted by your eye doctor.
In general, cylindrical eye disorders occur due to abnormalities of curvature in the cornea or lens of the eye, causing vision to be blurred or unable to see straight lines. Astigamtism disorders can be accompanied by disturbances in vision or near vision problems, depending on the results of the examination and evaluation of the doctor. Patients with cylindrical eye disorders can be accompanied by a variety of comorbid complaints, such as:
Unable to see straight lines See nights that are uncomfortable or not clear. Eyes get tired easily Photophobia Double vision Headache To help control cylindrical vision disorders, patients can do an examination and evaluation directly to the ophthalmologist, so the doctor can do a series of sharp vision examinations. The result of astigmatism examination between 0-0,6 diopters is the normal range, while between 0.6-2.0 diopters shows a mild astigamatism value, between 2.0 - 4.0 shows a moderate astigmatism value, and above the 4.0 value diopters show significant values.
If the results of your eyesight sharp examination show an astigmatism value of 3.75 for each eye, then the diopters value for your lens is 3.75 diaopters, the astigmatism lens strength values used for correction of astigmatism disorders with an angle of 180 degrees each. for the right eye and the left eye by 15 degrees. What needs to be known next is to ascertain whether this astigamtism is followed by disturbances of distant or near vision.
