Opticians typically makes the following adjustments to ensure your glasses fit comfortably and securely:
The temple tips should curve gently around the back of your ears. Your optician uses their fingers and thumbs to bend the temple tips to create a gentle curve, providing a secure fit without causing irritation.
If you have adjustable nose pads, your optician can squeeze the pads closer together or further apart to find the perfect fit on the bridge of your nose, allowing the glasses to stay in place comfortably.
The pantoscopic tilt is the angle of the lenses relative to your face. Your optician can adjust this angle by bringing both temples down to increase the tilt or up to decrease it, which is important for vision and can help prevent the frames from catching on your cheeks.
The bow angle is the curvature of the frame relative to your face. Your optician can mold the frames using their fingers and thumbs to adjust the bow angle, particularly on acetate frames by heating the area.
Tools Used by Opticians
Opticians use the following tools to accurately adjust your glasses:
This gauge makes it easy to set up a frame correctly and see exactly what adjustments are needed to achieve a symmetrical alignment of the frame on your face.
These tools are used to take precise measurements of the frame, the eye size, bridge size, side length, and head width.
These gauges are used to measure the frame's face form angle and the distance between the cornea and the back surface of the lens, which is crucial for individualised lens fitting.
By making these adjustments and using the appropriate tools, the optician can ensure your glasses fit perfectly, providing optimal comfort and vision.
