A glasses strap or glasses chain is normally attached to the ends of the glasses arms using two small loops. These loops are often made from silicone or rubber and have a small metal coil or sliding element for adjustment.
Attachment is simple and takes only a few moments. The important thing is that the loops sit securely without damaging the glasses arms or tightening around them too much.
How a typical attachment loop is constructed
Many glasses chains and straps have a flexible loop at each end. Each loop is slid over one of the glasses arms.
A typical loop usually includes:
- a flexible opening made from silicone or rubber,
- a small metal coil or sliding sleeve,
- a connecting ring linking the loop to the glasses chain or strap.
The metal coil is used to make the loop tighter or wider. This allows it to be adjusted to different arm thicknesses.
Attaching a glasses strap: step-by-step guide
Step 1: Place the glasses down safely
Place the glasses on a clean, soft surface. This helps prevent scratches on the lenses or frame.
Carefully open the glasses arms.
Step 2: Open the loops
Slide the small metal coil or adjustable element back slightly. This makes the loop larger and easier to guide over the glasses arm.
Do not pull the loop forcefully. Take particular care with delicate connecting rings.
Step 3: Slide the loops over the glasses arms
Guide one loop over the end of each glasses arm.
Slide the loop a little further forward. It should not sit only very loosely at the very end of the arm, as it can slip off more easily there.
On most glasses, the loop is well positioned when it sits in the rear section of the arm but still has sufficient distance from the hinge.
Step 4: Carefully tighten the loops
Slide the metal coil towards the glasses arm until the loop sits securely.
The loop should:
- not slip,
- not be excessively stretched,
- not deform the glasses arm,
- not cause visible pressure marks.
Tighten the loop only as much as is necessary for a secure hold.
Step 5: Check the fit
Carefully lift the glasses by the chain or strap just a few centimetres above the soft surface.
Check that both loops are secure. During this test, also support the glasses with one hand until you are sure that nothing can slip off.
Then put the glasses on and check how they feel.
Where should the loop sit on the glasses arm?
The ideal position depends on the shape of the arm.
As a general rule, the loop should:
- sit behind the ear area,
- not be attached directly next to the hinge,
- not be able to slip off the very end of the arm,
- be positioned as evenly as possible on both sides.
With straight or very smooth arms, it can be useful to slide the loops slightly further forward. With strongly curved arm ends, the curve itself often provides additional grip.
What should you do with very thin glasses arms?
On particularly thin metal arms, the loops may sit too loosely. In this case, carefully slide the adjustable coil further towards the arm.
Then check whether the loop remains secure when the glasses move.
If the loop still slips despite being adjusted tightly, a smaller replacement loop may be required. Suitable spare parts may be available in our accessories section.
What should you do with wide glasses arms?
Wide plastic arms require a larger loop opening.
First slide the metal coil back and widen the loop carefully. The material should not be stretched more than necessary.
With very wide arms, check whether the existing loop is large and durable enough. A loop that is too small can remain under constant tension and wear out more quickly.
Can the loops damage the glasses?
High-quality silicone or rubber loops are normally soft and gentle on glasses frames. Nevertheless, a few points should be observed:
- The metal coil should not rub directly against the glasses frame.
- The loop should not be tightened excessively.
- Dirt and sand should be removed regularly.
- Delicate or coated glasses arms should be checked from time to time.
- Damaged or brittle loops should be replaced.
Careful handling is particularly important with high-quality, lacquered or delicate frames.
Aligning a glasses chain correctly
After attachment, the glasses chain should run evenly behind the neck.
Make sure that:
- the chain is not twisted,
- both attachments sit at the same height,
- no beads or chain links are tangled,
- the glasses hang straight in front of the body,
- the connecting elements can move freely.
With beaded chains or delicate metal chains, knots should never be pulled apart with force. Lay the chain flat on a smooth surface and carefully loosen the affected area.
How tightly should the loops fit?
The loops must fit tightly enough that they do not slip off during normal use. However, they should not constrict the glasses arms.
A good fit is achieved when:
- the loop does not move by itself,
- it can still be adjusted carefully if necessary,
- the glasses arm shows no pressure marks,
- the material is not visibly overstretched.
Check the attachment regularly, especially if you use the glasses strap every day.
Removing the glasses strap
To remove it, carefully slide the metal coil back so that the loop opens.
Then slowly pull the loop over the end of the glasses arm. Do not pull on the chain or strap; hold the loop itself.
This protects connecting rings, clasps and delicate decorative elements.
Cleaning the attachment loops
Over time, skin oils, dust, cosmetics or residue from care products can collect on the loops.
A soft, slightly damp cloth is usually sufficient for cleaning. Dry the loops carefully afterwards.
Avoid aggressive cleaners, alcohol or solvents. These can damage the material and make it brittle.
For more information, see our guide on cleaning and caring for a glasses chain.
How often should the loops be replaced?
There is no fixed replacement interval. Check the loops regularly for:
- cracks,
- discolouration,
- excessive stretching,
- brittle areas,
- loose metal coils,
- damaged connecting rings.
As soon as a loop no longer holds securely, it should be replaced. Do not wait until it breaks completely.
Common mistakes when attaching a glasses strap
The loop sits only at the very end of the arm
This makes it easier for the loop to slip off. Slide it slightly further forward and adjust it to the correct size.
The loop is tightened too much
An excessively tight loop can place unnecessary strain on both the material and the glasses arm.
The metal coil rests directly against the frame
Position the loop so that hard metal parts do not rub continuously against the glasses.
The chain becomes twisted during attachment
Lay the glasses chain out flat before attaching it and check its alignment.
The glasses are lifted without first checking the attachment
Test the hold carefully over a soft surface first and support the glasses with your hand.
Frequently asked questions about attachment
Do glasses chains fit every pair of glasses?
Many models have adjustable loops and fit a wide range of glasses frames. With particularly wide, thin or unusually shaped arms, a different type of loop may be necessary.
Where is the glasses chain attached?
The loops are attached to both glasses arms. They should sit in the rear section of the arms and should not be positioned directly next to the hinges.
Can the loops be replaced?
On many glasses chains, damaged loops can be replaced. Make sure that the connecting rings and loop size are suitable.
Why does my glasses strap slip off?
The loop is often adjusted too loosely or sits too close to the end of the arm. Very smooth or particularly thin arms can also make it more difficult to achieve a secure hold.
Securely attached and always within easy reach
With correctly adjusted loops, your glasses remain securely connected to the glasses chain. Check the attachment regularly and replace damaged parts in good time.
