The provided question is nonsensical as glasses are not designed to be fitted to a human arm. The arms of glasses (temples) are designed to fit around the ears to hold the glasses in place on the face. Therefore, the accurate question would be how to adjust the temple arms for better fit and comfort around the ears.
Since the question is fundamentally flawed, a literal answer is impossible. However, if we reframe the question to address the fitting of glasses temples for better comfort, here's how it's done:
Adjusting Glasses Temples for a Better Fit
If your glasses are too tight, too loose, or press uncomfortably behind your ears, you can adjust the temple arms. However, exercise caution as excessive bending can break the frames, especially plastic frames. If you are unsure, seek professional help from an optician.
Tools You Might Need:
- Hair Dryer (for plastic frames): To gently heat the plastic and make it more pliable.
- Small Screwdriver (for frames with screws): To adjust the hinges.
- Soft Cloth: To protect the frames from scratches.
Steps to Adjust Plastic Frames:
- Heat the Temples: Use a hair dryer on a low setting to gently heat the area you want to adjust for about 20 seconds. Don't overheat.
- Bend Gently: Once the plastic is warm and pliable, gently bend the temple arm to achieve the desired curve. A good technique is to use your thumb to create a smooth curve.
- Try Them On: Put the glasses on and see how they feel. If they're still uncomfortable, repeat the heating and bending process in small increments.
- Cool and Set: Once you're happy with the fit, allow the plastic to cool down. This will help it retain its new shape.
Steps to Adjust Metal Frames:
- Locate Adjustable Parts: Look for hinges or nose pads that can be adjusted.
- Make Small Adjustments: Use pliers (with covered tips to protect the metal) to make small adjustments to the nose pads or temple arms.
- Try Them On: As with plastic frames, test the fit frequently and make adjustments in small increments.
- Tighten Screws: If you adjusted the hinges, make sure the screws are tightened securely after adjustment.
Important Considerations:
- Material: Be aware of the frame material (plastic, metal, titanium, etc.) as each requires different techniques and tools.
- Professional Help: If you are uncomfortable making adjustments yourself, or if your frames are delicate or expensive, seek professional help from an optician. They have the expertise and tools to safely adjust your glasses.
- Small Increments: Make adjustments in small increments to avoid over-bending or breaking the frames.
- Even Adjustments: When possible, adjust both temple arms equally to maintain balance and symmetry.
- Nose Pads: Adjusting the nose pads can also dramatically improve comfort, particularly for metal frames.
