How to Adjust Your Glasses at Home Safely

Quick answer

You can safely adjust most glasses at home using a small screwdriver, warm water, and gentle pressure. Focus on tightening screws, warming acetate frames to reshape them, and adjusting nose pads. Stop if you meet resistance — forcing a part can break the frame or lens.

Step-by-step guide to safe glasses adjustment

1. Tighten loose frame screws: Use a precision screwdriver to gently tighten the hinge screws on both temples. Turn clockwise until snug — do not overtighten or you may strip the threads. If a screw keeps spinning, it may need a drop of thread-locking fluid (available at most optical shops). Common mistake: using too much force, which cracks the frame around the hinge. Checkpoint: after tightening, open and close the temples. They should move smoothly with light resistance. If they bind, loosen slightly.
2. Fix a crooked frame: Hold the glasses with both hands and look at the bridge. If one side sits higher than the other, warm the temple that needs bending by running it under warm (not hot) water for 20-30 seconds. Gently bend the temple downward at the hinge area. For metal frames, you can bend without heat but use slow, controlled pressure. Common mistake: bending the temple too close to the ear hook, which changes the fit angle rather than fixing the level. Checkpoint: place the glasses on a flat surface. Both temples should touch the table evenly when open.
3. Adjust nose pads for a better fit: If your glasses slide down or pinch your nose, use your thumbs to gently push the nose pads inward (to tighten) or outward (to loosen). For silicone pads, you can also warm them slightly with a hair dryer on low heat to make them more pliable. Common mistake: adjusting only one pad, which makes the frame sit crooked. Always adjust both pads symmetrically. Checkpoint: put the glasses on and shake your head gently. They should stay in place without leaving red marks after 10 seconds.
4. Reshape acetate frames that feel too tight or loose: Acetate frames can be reshaped by warming them. Submerge the front of the frame in warm (not boiling) water for 30-60 seconds, then dry with a cloth. Gently widen the frame by pulling the temples outward (to loosen) or push them inward (to tighten). Hold the new shape for 10 seconds while the acetate cools. Common mistake: overheating the frame, which causes it to warp permanently or lose its color finish. Checkpoint: after cooling, check that both lenses are still seated firmly in the frame. If a lens pops out, stop and visit a professional.
5. Replace a lost or stripped screw: If a hinge screw is missing or stripped, use a replacement screw from an eyewear repair kit (available online or at optical shops). Match the screw length to the original — too long and it will protrude into the lens groove; too short and it won't hold. Insert the new screw and tighten gently. Common mistake: using a screw from a different frame model, which may have a different thread pitch and damage the hinge. Checkpoint: after replacing, test the hinge by opening and closing the temple several times. If it feels loose, the screw may be the wrong size.

Products that make adjustment easier

• FRANCOISE: Nina Mûr - Francoise combines modern design with sustainable craftsmanship, offering handcrafted wooden glasses made in Madrid. The frames are created from responsibly sourced birch wood using an advanced multi-layer lamination process. Wood frames like the Francoise require extra care during adjustment — never soak them in water. Use a dry cloth and only adjust the metal hinges with a screwdriver. The multi-layer lamination makes the frame durable but less flexible than acetate, so avoid bending the front.
