Many people encounter this issue: after wearing glasses for a while, the frames can become deformed. This deformation can result from improper removal and wearing methods, pressure on the nose, or incorrect lens height. Not only does this affect the appearance of the glasses, but it can also impact your eyesight.

If you don’t have time to visit an optician for adjustments, or if you need a quick fix, don’t worry. You can easily address some minor deformations on your own. Let’s explore how you can make these simple adjustments in this blog.

1. Inspection: Start by checking the fit of the glasses frame and examining the screws and lenses. Since the frame is made up of many small parts, ensure that the welding points are secure and well-made. A thorough inspection will help you assess the overall quality of the frame.

2. Locking Screws: Over time, the screws on the frame may become loose. Use a specialized screwdriver to tighten them. Be careful not to over-tighten, as this can make the glasses uncomfortable to wear and, in severe cases, cause the temples to break. After tightening, ensure the screws are snug but not too tight, to avoid any discomfort during use.

3. Tilt Angle: If the tilt angles of the temples are inconsistent, they may need adjustment. Use specialized glasses pliers to make these adjustments, but it's advisable to avoid doing this yourself to prevent damaging the frame.

4. Nose Pads: Adjusting the nose pads is straightforward. Ensure that the pads make full contact with the bridge of your nose and that the distance between the lenses and your eyes is approximately 12mm. If the distance is too large, gently press the base of the nose pads inward. Conversely, if the distance is too small, use adjusting pliers to gently move the pads outward.

5. Temple Length: If the angles of the temples need adjustment, it usually means that the inclination of the temples on both sides is uneven. For metal frames, use two pairs of pliers: one to hold the frame steady and another to adjust the angle in front of the temple hinge. (Note: Use a cloth to protect the glasses and ensure the hinge remains unaffected during adjustment). For plastic frames, heat the temples with a heater to soften them, then adjust the angle by twisting the temples to the desired position.

6. Temple Tips: Adjust the curvature of the temple tips to fit the wearer’s ears more comfortably. In colder weather, heating the plastic temple tips before adjustment is recommended, as they are more likely to break if adjusted without heat.

Glasses Slipping Down

If you notice that your glasses tend to slide down your nose, especially during sweaty conditions in the summer, here’s how to adjust the frame:

For metal frames, start by pushing the nose pads inward as much as possible. Use your thumbs to press the pads so they fit snugly against the sides of your nose. Additionally, you can slightly adjust the ends of the temples inward and downward to help keep the glasses in place.

For plastic frames, soak the glasses in a bowl of warm water for 30-60 seconds. After soaking, carefully apply pressure inward and downward to the ends of the temples to improve their fit around your ears.

Glasses Pressing on the Bridge of the Nose

If your glasses feel uncomfortable and press too much on the bridge of your nose, here’s how to adjust them:

Metal Frames: Use your thumb to gently widen the nose pads until they fit comfortably and relieve the pressure on your nose.

Plastic Frames: Soak the glasses in a bowl of warm water for 30-60 seconds. After soaking, carefully apply outward and upward pressure to the ends of the temples to relieve tension at the back of the ears.

Glasses with One Side Higher than the Other

This is a common issue of frame deformation, often caused by picking up or wearing the glasses with one hand. Fortunately, this problem can usually be corrected with simple adjustments. Here’s how:

• If the left lens is higher, lower the right temple slightly. Adjust it at the most flexible points, such as the hinge or the bend near the ear.

• If the right lens is higher, lower the left temple slightly. Make adjustments at the most flexible points, such as the hinge or the bend near the ear.

One Lens Closer to the Eye

If one lens is closer to your eye, it often indicates that the frame is deformed due to uneven tightness of the temples. This issue can be exacerbated by removing the glasses with one hand. To prevent this, it’s best to always take off your glasses with both hands. Here’s how to adjust the fit:

• If the left lens is closer to your eye, adjust the left temple inward or the right temple outward. 

• If the right lens is closer to your eye, adjust the right temple inward or the left temple outward.

The above methods are commonly used to adjust glasses deformation. However, keep in mind the following principle: always soak the frame in hot water first, but avoid soaking the lenses. Adjust the soaking position to ensure only the frame is heated. Alternatively, you can use a hair dryer to warm the frame.

If the adjustment isn’t perfect after the first attempt, you can make additional adjustments. Just be sure not to apply too much force. After reading this article, you should have some useful tips for repairing your glasses.
