loose screws: doing it properly without damaging the frame

A step-by-step approach to loose screws, what to avoid, and when the job should go to an optician instead of being attempted at home.

What to avoid

Material changes the method: acetate can be warmed and polished, metal can be tightened and replated, horn and wood need oiling instead. Titanium and beta-titanium hold their shape but need specific tools, so home adjustment usually makes the fit worse. Take the frame to an optician when a hinge has play, when a lens is loose in its groove, or when the front sits visibly asymmetric.

Material differences

Professional adjustment costs little, takes minutes and is the difference between a frame that lasts a decade and one that fails in a year. Prevention is cheaper than repair: hard case, temples folded inward, and never resting the frame face-down on a hard surface. A frame with even wear, tight hinges and clean original lenses sells faster and for more than a neglected example of the same reference.

When to see an optician

When you list on FRAMEO, note any professional work in the description; disclosed restoration builds trust and reduces returns. loose screws sounds trivial until a frame is ruined by it, and most of that damage comes from good intentions applied with the wrong tool. A frame is a mechanical object with tolerances measured in tenths of a millimetre, which is why patience beats force every time.

Keeping it that way

The kit is small: microfibre cloths, mild soap, a precision screwdriver, and a hard case. Nothing abrasive, nothing solvent-based. Work over a soft surface and with the frame closed where possible, so a slip does not become a bent temple or a chipped lens edge. Do the job in daylight rather than under a lamp: it is the only reliable way to see whether the result is even on both sides.

Value impact

Never use alcohol, acetone, kitchen degreasers or paper towels; each of them attacks either the coating, the finish or both. Heat is the other enemy. Hot water, hairdryers and car dashboards deform acetate and loosen lens seating. Material changes the method: acetate can be warmed and polished, metal can be tightened and replated, horn and wood need oiling instead.

Frequently asked questions

Can I do this at home?
The cleaning and light screw tightening, yes. Anything involving heat, hinge play or lens seating belongs with an optician.
What should I never use?
Alcohol, acetone, household degreasers, paper towels and hot water. All of them damage coatings, finishes or the frame material itself.
Does maintenance affect resale value?
Significantly. Even wear, tight hinges and clean lenses sell faster and higher than the same reference in neglected condition.
