Sunglasses are an important accessory that protect our eyes from harmful UV rays. Proper storage is essential to keep sunglasses in good condition so they can continue protecting our vision. There are several factors to consider when determining the best way to store sunglasses, including the frame material, lens type, and storage conditions like temperature, humidity, direct sunlight exposure, and potential for scratches.
Where Should Sunglasses Be Stored?
The ideal storage location for sunglasses depends on how often they are used. For sunglasses used every day or frequently, storing them in a protective case in an easily accessible location is best. Common storage spots include purses, backpacks, glove compartments, and hanging on hooks or stands near the door for grabbing on the way out.
For infrequently used sunglasses, a closet, drawer, or cabinet helps protect them from dust and scratches. Avoid storing in the bathroom or places with rapid temperature and humidity changes which can damage frames and lenses over time.
How Should Sunglass Lenses Be Positioned During Storage?
Lenses should be stored facing away from direct light whether hung on a stand or placed in a case. This prevents the concentrated light from damaging the lenses or frames over time.
If possible, store sunglasses with lenses perpendicular to rather than parallel to the opening of the case. This minimizes the chance of accidental scratches or fractures during placement into storage or removal for use.
What About Temperature and Humidity?
Consistent, moderate temperature and humidity are ideal for sunglass storage. Aim for around 68°F (20°C) and 35-45% relative humidity if possible. Avoid storage places that get very hot like in cars on sunny days or extremely cold such as near air vents.
Rapid temperature fluctuations can cause expansion and contraction of the frames, weakening joints and increasing the chance of breakage. Excessive humidity may damage lenses or fog them up when taken out for use. Very low humidity can dry out and crack frames and lenses.
Should Sunglasses Be Stored in Their Original Case?
It depends. Many sunglasses come with a protective case when purchased. If this case has a soft lining and snug fit for the specific sunglasses, then the original case is a great storage option. Soft lining and contoured shape prevent jostling, scratches, and damage.
However, some original cases are loose fitting and made of thin, hard plastic. These don’t provide much protection. Aftermarket cases lined with microfiber or felt offer better security for many styles. Hard-shell cases guard against crushing but the inside should still be lined.
Are Display Racks Good Sunglass Storage?
Sunglass display racks can be an acceptable storage option for some frequently used sunglasses. Look for display hooks lined with felt, microfiber or another soft material to avoid scratching. Avoid overcrowding hooks to prevent frames knocking together.
Most display racks are meant more for decorative display rather than long-term storage. Make sure sunglasses are not parked for prolonged periods in direct sunlight which can damage the frames and lenses. Displays near exterior windows are also risky due to temperature fluctuations.
Tips for Storing Specific Frame Materials
Certain frame materials have particular care requirements:
Plastic Frames
– Avoid letting plastic frames sit in very hot or very cold conditions which makes them brittle and prone to cracking when flexed.
– Don’t use cleaning solutions, even ones labeled “lens cleaner”, on plastic frames as they can damage and discolor the material.
– For long-term storage, keep plastic frames out of direct sunlight to avoid sun damage and fading.
– Prevent scratches by lining cases with microfiber or other soft materials.
Metal Frames
– Keep metal frames dry to avoid corrosion and rusting.
– Absorbent liners in cases can trap moisture against metal frames, so use non-absorbent linings.
– Avoid humid storage environments. If living in a humid climate, consider keeping metal frame sunglasses in a dehumidified closet or cabinet.
– Gently clean metal frames with non-abrasive cloth before storage to prevent tarnishing.
Cellulose Acetate Frames
– Cellulose acetate frames don’t withstand temperature extremes well. Avoid very hot or cold conditions.
– Dry conditions cause the most damage by making these frames brittle. Store in a humidity-controlled environment.
– Keep cellulose acetate frames out of direct sunlight which can accelerate damage from heat and UV exposure.
– Prevent scratching by using lined cases and not letting the glasses rub together when stored.
Storing Lens Types
Certain lens materials and treatments also benefit from tailored storage:
Glass Lenses
– Glass is prone to chipping and shattering with hard impact. Use very padded cases lined with microfiber or another soft material.
– Avoid overcrowded drawer storage where the glasses could bang together. Hooks, stands, and compartments cases work better.
– Keep glass lenses dry to avoid minerals depositing on the surface.
Polycarbonate Lenses
– Polycarbonate lenses are impact-resistant but still prone to scratching. Line cases with soft microfiber.
– Avoid overcrowded storage areas where the lenses could rub together.
– Don’t use cleaners containing ammonia, bleach, or alcohol which can damage the surface over time.
Photochromic or Polarized Lenses
– Avoid storing photochromic lenses in places where sunlight or UV light could reach them, like near windows. The lenses will partially darken over time even when not being worn.
– Polarized lenses are prone to delamination damage from excessive heat. Avoid hot places like cars.
– The coatings on photochromic and polarized lenses can degrade if stored in humid conditions long-term.
How Should Sunglasses Be Cleaned Before Storage?
Gently wiping sunglasses before storage clears away dust, dirt, skin oils, and other debris that could slowly damage frames and lenses over time.
Use a microfiber cloth dampened with warm water to gently wipe down the frames. Carefully dry with a clean, lint-free microfiber cloth.
For the lenses, use a microfiber specifically designed for lens cleaning along with an alcohol-free lens cleaning spray. Spray a small amount onto the cloth then gently wipe lenses.
Avoid using paper towels or tissue paper that can scratch. Don’t use cleaners containing ammonia, bleach, or alcohol which can damage frames and lenses.
What About Long-Term or Seasonal Sunglass Storage?
For sunglasses only used occasionally or stored for the off-season, take additional protective steps:
– Clean the sunglasses thoroughly before storage to remove debris.
– Store in a protective hard case with plush lining to prevent scratching.
– Wrap frames and case in a clean microfiber cloth for added scratch protection.
– Keep stored away from heat, humidity, and direct light in a closet or drawer.
– If possible, include a desiccant pack in the case to prevent moisture buildup.
– For long-term storage beyond 6 months, place sunglasses in an airtight plastic bag for added protection.
How Should You Store Expensive Designer Sunglasses?
Designer sunglasses often have premium and delicate materials needing special care:
– Always store in the original protective case if it’s lined or has molded shape slots.
– If the original case is flimsy, invest in an aftermarket sunglass case with plush microfiber lining. Felt lining can still allow some scratching.
– Avoid crowded sunglass displays and drawers. Hooks, stands & compartmentalized cases are best.
– Don’t store in very hot, cold or humid environments that could damage frames and lenses.
– Keep away from direct sunlight and heat sources like heater vents.
– Consider using silica gel packs in an airtight container for long-term designer sunglass storage.
– For extra protection, wrap glasses in a microfiber cleaning cloth before placing in case.
– Clean gently before storage using microfiber cloths and alcohol-free cleaners.
Tips for Kids Sunglasses Storage
Kids sunglasses require some specialized storage strategies:
– Select cases with kid-friendly designs and colors to promote use. A boring case may get ignored.
– Teach kids how to properly put on and remove sunglasses from storage cases to prevent bending and breaking.
– For school lockers, choose hard cases to prevent crushing. Soft cases can get smashed.
– Look for cases with lanyard or bag clips making it easier for kids to keep track of their sunglasses.
– Avoid kid’s displays with loose, dangling hooks. Opt for compartments cases or stands instead to limit damage.
– Set rules for where kids should store their sunglasses at home when not being worn. Assign a designated spot.
Preventing Sunglass Damage in Bags
Sunglasses tossed loosely into bags are prone to bending, scratching, and breaking. Use these tips to prevent damage:
– Store sunglasses in a protective case and then place the case in the bag. Hard cases prevent crushing.
– If not using a case, slip sunglasses into a microfiber sleeve or pouch before putting in the bag.
– With loose glasses, keep them towards the top of the bag to limit shifting around and weight on top.
– Avoid overstuffing bags which puts pressure on stored sunglasses.
– Place delicate sunglasses in a small pocket of their own to keep isolated.
– For kids’ bags, provide designated padded sunglass pouches and enforce their use.
– In purses, keep sunglasses in a case in an outside pocket, not jumbled near keys and loose items.
Can Sunglasses Be Stored in Cars?
Leaving sunglasses long-term in cars is risky due to temperature extremes. But for frequently used pairs, temporary car storage can work with precautions:
– Keep in the glovebox rather than on seats where they can slide off and get damaged. The glovebox provides some padding as well.
– Store in a protective hard case rather than loose. Soft cases can get crushed.
– Avoid leaving sunglasses in the car for extended periods if it will be very hot or cold. Only short term.
– Don’t leave in the console or mount near windows where sunlight can reach the lenses and damage them.
– Remember that car interiors heat up tremendously even when parked in the shade. Don’t leave sunglasses when running quick errands.
– At night, bring the sunglasses in from the car instead of leaving until morning. The cold can damage some frames.
– When driving, put on sunglasses and remove any spares from sunny spots near windows.
Displaying Sunglasses at Home Safely
It’s tempting to show off cool shades at home but avoid damage with these display tips:
– Choose display locations out of direct sun from windows and lamps to avoid damage to frames and lenses.
– Prevent dust by avoiding open shelves or tabletops. Use glass door display cabinets or shadowboxes.
– For open displays, keep cleaning supplies handy like microfiber clothes and alcohol-free spray to regularly dust.
– Opt for compartmentalized, lined displays rather than loose hooks to prevent scratching and knocking together.
– Make sure displays are secure and won’t be knocked over by pets, kids, or cleaning. Use museum wax if needed.
– Consider rotating sunglasses on display if you own many pairs. Store the majority properly and just display special ones short term.
The Worst Ways to Store Sunglasses
Some common practices can ruin your sunglasses. Avoid these storage mistakes:
– Random loose drawers or shelves where they slide around and scratch.
– Tossing on tables and counters where they can get knocked off and stepped on.
– Overstuffed handbags bumping against other items.
– Hanging crooked on vehicle mirrors creating bending and warping.
– On dashboard or back window ledge exposed to direct sunlight.
– Open bathroom shelves with constant humidity and heat from showers.
– Cluttered displays with loose, dangling hooks allowing glasses to bump and scratch.
– Near heat and cold sources like appliances and air vents.
Storage for Bent Frames
If sunglass frames become bent out of shape, don’t store them folded or they may take a permanent set. Instead:
– Carefully bend frames back into proper shape using your hands. Avoid forcing.
– Fill a sink or bowl with very hot water.
– Dip plastic frames for 30 seconds to soften and make the frames malleable for repositioning.
– For metal frames, soak a washcloth in the hot water then wrap around frames for a minute before reshaping.
– Reshape frames gently by hand while heated then place on a flat surface to fully cool in the correct shape.
– Once cooled, frames should hold corrected form but avoid bending again. Store carefully.
Key Takeaways for Proper Sunglass Storage
Follow these sunglass storage best practices:
– Store in a lined, protective case when not in use.
– Keep out of direct sunlight, heat, and humidity extremes.
– Position lenses facing away from case openings or hang perpendicular.
– Clean gently with microfiber cloth before storage.
– Avoid loose drawers, bags and displays that allow bumping and scratching.
– Tailor storage to frame and lens material needs.
– Fix bent frames before storage.
– Keep most sunglasses properly stored. Only display special pairs short term.
Conclusion
Sunglasses are worth protecting by storing properly between uses. Keep them safe from damage using lined cases, temperature control, avoiding moisture and direct light, cleaning regularly, and being mindful of frame and lens material vulnerabilities.
