Glasses are fitted by ensuring the frame sits comfortably and securely on your face, primarily relying on the "three-point touch" rule and adjustments for optimal vision and comfort.
Here's a breakdown of the fitting process:
- Initial Assessment: An optician or eye care professional will assess your face shape, pupillary distance (PD), and the height of your eyes in relation to the frame.
- Frame Selection: You'll select a frame that suits your style and face shape. The optician can guide you to frames that are likely to fit well based on the measurements taken.
- The Three-Point Touch: A good fit relies on the "three-point touch" rule. This means:
- The frame should rest gently on your nose.
- The temples (arms) of the glasses should sit comfortably and securely on the top of each ear.
- Adjustments: Once you've chosen a frame, the optician will make adjustments to ensure a proper fit. These adjustments may include:
- Nose pads: Adjusting the nose pads to ensure the frame sits correctly on your nose and doesn't slide down.
- Temple arms: Bending the temple arms to ensure they sit comfortably and securely behind your ears without causing pressure or discomfort. They should follow the contour of your head without digging in.
- Frame width: Adjusting the overall width of the frame to prevent it from being too tight or too loose. If the frame is too narrow, the glasses will constantly slide down your face and need adjustments.
- Checking the Fit: After adjustments, the optician will check the fit to ensure:
- The glasses sit straight on your face.
- Your eyes are centered in the lenses.
- You can see clearly through the lenses.
- The glasses are comfortable to wear.
- Fine-Tuning: Minor adjustments are often necessary after wearing the glasses for a few days to ensure long-term comfort.
Essentially, the fitting process combines precise measurements, frame adjustments, and user feedback to create glasses that are both visually effective and comfortable to wear.
