How to Store Sunglasses

Lenses up, case closed, never in a hot car, never pushed onto your head. The rules are short — what matters is making the right place the easy place, because almost all sunglasses damage happens during storage rather than during wear.

How this is funded: we earn a commission if you buy through our links, at no extra cost to you. It never changes which product we recommend, and we’ll tell you when we’d skip one. Full disclosure.

Clean, folded, lenses up, in a case, somewhere cool. That is the whole answer, and if you only take one thing from this page take the last part: a hot car is the single most destructive place to keep sunglasses, worse than a bag full of keys. Everything else here is about making the right place the easy place, because almost all sunglasses damage happens while they are not being worn.

A word on what this page is not. We sell nothing in this category — our registry is eyewear, not cases or stands — so there is no case recommendation here and no affiliate reason for one to exist. The only genuine product answer to a storage problem is further down, and it is not a case.

The five rules

1. Clean them before you put them away

This is the one that actually prevents scratches. Grit left on a lens gets pressed against the case lining, or ground in by the next dry wipe. Rinse with cool water, dry with a microfiber cloth, and never dry-wipe a dusty lens. Our cleaning guide covers the household products that destroy coatings, which is a shorter list than you would hope.

2. Fold the left temple first

Most frames are hinged so the left arm folds under the right, and they sit flatter that way. A frame stored twisted holds the twist, and a twisted frame is a crooked fit; our adjustment guide is largely about undoing this.

3. Lenses up, never lenses down

If they are going on a surface without a case, fold the temples and let those take the weight with the lenses facing up and away. The lens is the part you cannot replace cheaply.

4. A hard case for crushing, a pouch for scratching

These do different jobs and people treat them as interchangeable. A hard case stops a frame being sat on. A soft pouch only stops the lens rubbing against other things. If a frame matters to you, it wants the hard case. If it is going into a bag, it wants both.

5. Keep them out of heat

Sustained heat is what destroys good sunglasses. It softens plastic frames so they lose the shape an optician set, it can distort lens curvature, and it can delaminate a mirror coating or the polarizing film laminated inside the lens. A closed car in summer is far hotter than the air outside it. If you keep a pair in the car — and most people should, because the pair you have with you is the pair that protects you — keep it in the glovebox, and keep it cheap.

The three habits that cause most damage

Wearing them on your head. Your head is wider than the frame, so this holds the temples sprung apart. Do it every day and the frame stops gripping, which is the usual answer to why sunglasses slide down. It also transfers hair product onto the inside of the lens.

Hanging them from a collar. One temple takes the whole load, pulling the frame out of alignment, and the glasses get knocked whenever you move.

Loose in a bag or a door pocket. Keys, coins and sand are harder than a lens coating. A microfiber cloth wrapped round them is a surprisingly good substitute for a case, and it is already in the box they came in.

Storing a collection

Two principles: frames must not touch each other, and they should not sit in sunlight. A drawer insert, a divided tray or individual pouches all work; a shared box is how a collection scratches itself without anyone wearing anything. Check hinges on pairs that sit unused, because hinge grease dries out and a stiff hinge is where an acetate frame cracks. And keep the original case for anything valuable enough to travel with, because the brand warranties are no help here — Oakley, Maui Jim and Knockaround all treat scratches and accidental damage as normal wear or outright exclusions, which our repair guide goes through in detail.

The one product answer to a storage problem

The real reason sunglasses get stored badly is that the pair is never where you are. People put them on a table lens-down because the case is in a different room, and leave them in a car because that is where they needed them. The fix that actually works is not a better case: it is enough cheap pairs that one lives in every place you need one, so the good pair stays in its case.

These two entries exist in our registry for exactly that. Both state a UV400 lens, which is the one spec we will not compromise on at any price — see what UV400 means. Specs are read from each product’s own listing on the dated visit shown on its card, prices are pulled live, and we have not field-tested either.

#1Best for keeping a pair in every room

Paleshy 6-Pack Polarized

Six polarized UV400 pairs for the price of one mid-tier frame. The honest case for a multipack is not that any single pair is good — it is that a pair in the car, a pair in the kit bag and a pair by the door means you are wearing UV protection on the days you would otherwise have gone without. Judge it as insurance, not as eyewear.

Strengths

  • Polarized and UV400 stated across the pack
  • Per-pair cost low enough that losing one does not matter
  • Classic lightweight shape that suits most faces

Trade-offs

  • Budget hinges and coatings — these will not last like one good frame
  • No lens material, frame material or weight published

Spec note. The listing states polarized UV400 lenses across a six-pack. No lens material, frame material or weight is published, which is typical at this price.

#2Best cheap pair to leave in a bag

Duduma Polarized Sports

One of Amazon's long-running budget sport bestsellers. The Duduma is polarized, UV400, and built on a TR90 wrap frame — a lot of sport sunglass for under $20. It's not premium, but as a knock-around fishing or cycling backup, the polarization does the job.

Strengths

  • Polarized and UV400 on a TR90 wrap frame, under $20
  • Wrap coverage for cycling, fishing and running
  • Cheap enough to keep a pair in every bag

Trade-offs

  • Budget lens clarity and coatings
  • Generic sport-wrap look

That is deliberately a short list, and it is the honest one: a storage question mostly does not have a product answer, and we would rather say so than invent a recommendation for a case we have never seen. If the pair you are trying to protect is already scratched, the more useful page is do sunglasses expire, which sets out when a lens is past the point where storing it carefully helps.

Frequently asked questions

What is the best way to store sunglasses?

Clean, dry, folded left temple first, lenses facing up, in a hard case, somewhere cool. That covers nearly every avoidable failure. The reason most people do not do it is friction rather than ignorance: the case is in a drawer and the sunglasses are in your hand at the front door. The fix is logistical — keep the case where you take the glasses off, not where you think they ought to live. A pair with a home gets put away, and a pair without one gets put on a table lens-down.

Is it bad to leave sunglasses in the car?

Yes, and it is the most common way good sunglasses are ruined. A closed car in summer reaches temperatures far above the outside air, and sustained heat softens plastic frames so they lose their adjusted shape, can distort lens curvature, and can delaminate a coating or the polarizing film laminated inside a lens. Metal frames conduct enough heat to be unpleasant to put on. If you keep a pair in a vehicle, keep it in the glovebox or a door pocket out of direct sun, and make it a cheap pair you can replace.

How do you store sunglasses without a case?

Rest them on the folded temples with the lenses facing up, so nothing touches the lens surface. If they are going into a bag, wrap them in a microfiber cloth — the one that came with them — or in any soft fabric, and keep them away from keys and coins. A rigid pocket is better than a soft one. What you should not do is push them onto your head, hang them from a shirt collar, or lay them lens-down on a table, which are the three habits that account for most scratched lenses and sprung hinges.

Should sunglasses be stored lenses up or down?

Lenses up, always, if they are not in a case. The lens is the expensive part and the easiest to damage, so the rule is simply never to rest it on a surface. Fold the temples and let those take the weight. In a hard case it does not matter, because nothing is touching the lens either way — but if the case has a soft lining with grit in it, that grit is pressed against whichever surface faces down, so cleaning the glasses before storing them matters more than the orientation does.

Does wearing sunglasses on your head damage them?

It stretches them, yes. Your head is wider than your frame is designed to be, so resting sunglasses up there holds the temples sprung apart; do it daily and the frame no longer grips at the temples, which is why pairs that live on people's heads end up sliding down their noses. Hair products and scalp oils also get onto the inside of the lens and the hinges. It is not a dramatic failure, just a steady one, and it is the leading cause of the complaint in our guide on why sunglasses slide down.

How should I store a collection of sunglasses?

Separately, so they cannot touch each other, and out of light. A drawer insert, a shallow tray with dividers, or a row of individual pouches all work; a shared box where frames rub is how a collection acquires scratches without anyone wearing anything. Keep them somewhere cool and dry rather than on a sunny windowsill, and keep each pair's own case if the frame is valuable enough to travel. If pairs sit unused for long periods, check the hinges occasionally — grease dries out and a stiff hinge is a cracked frame waiting to happen.

Do sunglasses degrade in storage?

Slowly, in two ways that both matter more than the calendar. Coatings and the laminated polarizing film are the parts heat and humidity act on, which is why where you store a pair matters more than how long. And a lens that was already scratched does not improve: scratches scatter light where you are trying to see through it, and on a lens whose ultraviolet protection is a surface treatment rather than a property of the material, deep abrasion can compromise what the lens claimed. There is no expiry date, but there is a condition threshold.
