To provide our customers with the best care and service, we have implemented a verification system that is in compliance with the requirement of Kementerian Kesihatan Malaysia (KKM) for our customers. This regulation is to ensure all our valued customers are being sold with the correct prescription power and to prevent eye complications after wearing the purchased contact lenses.
Having said that, we also provide FREE contact lens prescription verification service (by registered optometrist) before customer place the order. However, even if you had obtained your prescription but still unsure of what prescription power you should choose, you may submit your prescription slip to us and we will seek our authorised Optometrist to advice on which prescription power that is most suitable for you.
1. Upload your copy of prescription
You can provide us a copy of your valid prescription slip written by an eye care professionals. You can either scan or snap a picture of your written prescription.

OD: OD stands for oculus dexter, the Latin phrase for “right eye.”
OS: OS stands for oculus sinister, the Latin phrase for “left eye.”
If both the left and right eye has the same diagnosis and prescription information, the abbreviation “OU” is used instead, or “ocular uniter,” meaning both eyes.
Sphere (SPH): This indicates the amount of lens power, measured in diopters (D), prescribed to correct myopia (nearsightedness) or hyperopia (farsightedness). The spherical power of a lens is indicated with a plus sign (+) for hyperopia and a minus sign (-) for myopia. Tintiris only supplies Myopia lenses at the moment.
Cylinder (CYL): This indicates the amount of lens power for astigmatism. If no cylinder power is noted, either you’ve no astigmatism or your astigmatism is so slight that it is not really necessary to correct it with your eyeglass or lenses.
Axis: This describes the degree and direction of your astigmatism. The axis is a figure which determines the angle of the correction needed to see clearly, measured in degrees from 1 to 180.
Base Curve (BC): The base curve determines what type of fit is required for the lens to meet the curve of your eye. This is usually written in millimeters or sometimes with the words: flat, median or steep.
Diameter (DIA): The diameter of a lens determines what length of width that best fits your eye. It measures the width of a lens in millimeters, from end to end.
