How to Install Replacement Arm on Eyeglasses

What you need

• A small optical screwdriver (usually Phillips or flathead)

• Replacement temples that match your frame’s model or hinge type

• A clean table or towel (to avoid losing screws)

• Optional: extra hinge screws (often needed)

---

Inspect the hinge type

There are 3 common types:

• Standard hinge – simple open/close

• Spring hinge – temples flex outward

• Hinge with exposed barrel – easy to access screw

If it's a spring hinge, replacing the temple is often harder but still doable.

Remove the old temple

1. Open the temple fully.
2. Hold the frame steady.
3. Unscrew the hinge screw (lefty-loosey).
4. Lift off the old temple.

⚠ If the screw is stuck, add a tiny drop of rubbing alcohol to dissolve old debris.

Prepare the new temple

• Line up the barrel holes (the small metal loops) with the hinge on your frame.
• Make sure the replacement is the correct side (left vs. right).

Temples are not interchangeable.

Insert the screw

1. Hold the new temple perfectly aligned.
2. Insert the hinge screw through the barrels.
3. Tighten the screw (righty-tightie).
4. Don’t overtighten—you can strip the screw.

If the screw won’t go in:

• Rotate the temple slightly until the barrels line up
• Use a longer screw temporarily to realign the hinge

Test the movement

• Open and close the temple
• Make sure the temple is secure but not stiff
• If loose, tighten slightly
