  Lens materials including:

Polycarbonate lenses are the most impact resistant material (shatter resistant) and most suitable for children or active adults. They provide the best eye protection of any lens and include 100% UV protection. They are thinner and lighter than CR-39 plastic lenses. The suggested prescription range is (0, no Rx) to +/-5.00 sphere and 0 to -2.0 astigmatism.

Hi-Index1.61 lenses are good for higher prescriptions because they do not look thick, do not magnify or minify your eyes when seen by others, and are lighter. The suggested prescriptions range is +/4.00 to +/-8.00 sphere and 0 to -2.0 astigmatism. Good for everyday use.

  These 3 points we need to know to make the lenses:

 1). Diopter: left = (-5.00), right = (-5.00)       ------- this is an example for your reference.

 2). For PD: (pupil distance, the distance from the centre of left eye to the centre of right eye)

 3). Astigmatism: If your eye have astigmatism, please provide the power of astigmatism and axis.

How to read your prescription (Rx)?

  Your prescription provides us with your doctor's recommendation for clear and comfortable vision. When ordering prescription eyeglasses online, be sure your eye doctor writes your Pupillary Distance (PD) measurement on your prescription. This ensures the optical center of your lenses will be exactly in front of your pupils.

Please review your information with our 4 samples bellow:

Prescription Glossary:

                               RX - Your Prescrition

                               O.D. / Oculus Dexter- Right Eye

                               O.S. / Oculus Sinister - Left Eye

                               O.U. - Both Eyes

                               SPH / Spherical - Corrective power for distance or reading; near (-) or far (+) sightedness

                               CYL / Cylinder - Corrective power for astigmatism (if applicable)

                               Axis - Corrective axis for astigmatism; it is an angle between 0 and 180 degrees (if applicable)

                               PD - Pupillary Distance or the distance between the center of each pupil (in mm)

                               PL / Plo / Plano - Placeholder for the number zero; you may leave the fields blank or enter 0.00

                               Prism - When the two eyes are not properly aligned and looking directly at the same thing, prism can be ground in to the lenses in order to re-align them (if applicable)

                               Base - The base is to the prism what the axis is to the cylinder (if applicable)

                               DV - An abbreviation for Distance-Vision

                               NV / NVO - Near-Vision or Near-Vision-Only; your optician is recommending reading-only glasses

                               -100 = - 1.00

                               +225 = +2.25

Please Note:

Astigmatism correction ("CYL / Cylinder"). Some doctors write their prescriptions in plus (+) cylinder and some in minus (-) cylinder. They are not the same. Take special note of this when entering your prescription later. If you don't see anything there, leave it blank.

Your doctor may use a blank Rx pad, not a pre-made Rx pad for eyeglasses only. If this is the case, you can draw imaginary grid-lines to separate the numbers. It will separate the different values more easily for you. The top power is always the right eye & the bottom power is always the left.

If you don't see numbers in some of the boxes (if there is no CYL or AXIS or ADD), leave those values blank when ordering. If you only see one number for each eye, it's the "SPH / Sphere" power; leave all the other fields blank.

It is common for the doctor to sometimes leave out the decimal points. If you see a number like -100 or +225, it is understood that your doctor means -1.00 or +2.25., respectively. Also, an axis of 5 or 05 is the same as 005; 70 is the same as 070. It's like using abbreviations or writing in short-hand.

If you have no astigmatism in one or both eyes, your doctor may just write the sphere power alone, or may use placeholders like sph ("sphere") or D.S. ("diopters sphere") instead.

   If you need help in understanding any part of your prescription, please contact us to ensure everything is entered correctly as prescribed. We are here to assist you and we want your glasses to be made exactly to your doctor's specifications.
