Adjusting glasses lenses typically involves correcting a frame imbalance that causes the lenses to appear uneven. It's not directly adjusting the lenses themselves, but rather tweaking the frame so the lenses sit correctly in front of your eyes.
Here's how to adjust your glasses if one lens appears higher than the other:
-
Determine which temple arm to adjust: If the left lens is higher than the right, you need to bend the right temple arm down. Conversely, if the right lens is higher than the left, bend the left temple arm down.
-
Locate the adjustable area: The best place to make adjustments is usually at the hinge (where the temple arm connects to the frame front) or at the bend near your ear.
-
Apply gentle pressure: Using your fingers, gently bend the temple arm in the desired direction. Make small adjustments and check the fit frequently. Avoid forcing the frame, as this could cause it to break.
Detailed Breakdown:
Let's say the left lens is sitting higher than the right lens. This indicates the right side of the glasses needs to be raised. To accomplish this, you'll focus on adjusting the right temple arm.
-
Heating (Optional but Recommended): If your frames are plastic, gently warming the area you want to adjust with a hairdryer (on a low setting, held at a distance) can make the plastic more pliable and less likely to break. Be careful not to overheat them. Metal frames generally don't require heating.
-
Bending at the Hinge: If you're adjusting at the hinge, use your fingers to gently bend the right temple arm downward. This will effectively angle the frame so the right lens sits higher.
-
Bending at the Ear Bend: If you're adjusting at the ear bend, gently bend the arm downward to achieve the same effect. This is often a more subtle adjustment.
-
Checking the Fit: After each small adjustment, put your glasses on and check the alignment of the lenses. Look in a mirror to ensure they appear even.
-
Repeat: Continue making small adjustments and checking the fit until the lenses appear level.
Important Considerations:
-
Professional Adjustment: If you're uncomfortable making these adjustments yourself, or if your glasses are significantly misaligned, it's best to take them to an optician. They have specialized tools and expertise to adjust your glasses properly. Many opticians offer this service for free or a small fee.
-
Material Matters: The method of adjustment can vary depending on the frame material. Plastic frames are more susceptible to breaking, so use extra caution. Metal frames are generally more durable but can still be damaged with excessive force.
-
Symmetry: Besides lens height, pay attention to the overall symmetry of the frame on your face. Are the lenses equidistant from your eyes? Is the frame sitting straight across your nose?
-
Nose Pads: If your glasses have adjustable nose pads, you can also use these to fine-tune the fit. Adjusting the nose pads can influence the height and angle of the lenses.
When to Seek Professional Help:
- If you are unsure of the frame material.
- If the frame is very old or fragile.
- If you are not comfortable making adjustments yourself.
- If the glasses are severely bent or damaged.
