- Stand in front of a mirror with good lighting.
- Hold a ruler horizontally against your brow, ensuring it is straight and level.
- Close one eye and align the zero mark of the ruler with the center of your open eye’s pupil.
- While keeping the ruler steady, open the closed eye and close the previously open eye.
- Note the measurement on the ruler that aligns with the center of your newly opened eye’s pupil.
Method 2: Using a Smartphone App or Online Tool
There are various smartphone apps and online tools available that can help measure your pupillary distance accurately. These tools use your device’s camera to capture an image of your face and calculate the PD based on facial landmarks. Follow the instructions provided by the app or tool to ensure accurate measurements.
Remember, if you are unsure about measuring your pupillary distance at home, it is always best to consult with an optometrist who can provide precise measurements for your glasses prescription.
3. What are the different components that make up a glasses prescription form?
A glasses prescription form typically consists of several components that provide specific information about each eye’s visual correction needs. The main components include:
Patient Information:
This section includes details about the patient, such as their name, date of birth, contact information, and any relevant medical history. It helps identify and track individual patients’ prescriptions accurately.
Sphere (SPH):
The sphere component of a prescription indicates the lens power required to correct nearsightedness (negative values) or farsightedness (positive values). It is measured in diopters and may have different values for each eye.
Cylinder (CYL):
If the patient has astigmatism, the cylinder component will be present. It denotes the additional lens power needed to correct the irregular curvature of the cornea or lens. Like sphere, it is measured in diopters and can vary between eyes.
Axis:
The axis is only applicable if there is a cylinder value present. It indicates the angle at which the cylindrical correction should be placed on the lenses to align with the astigmatism axis. The axis is measured in degrees from 0 to 180.
