Okay - we've all been there. You blindly reach for your trusty pair of sunglasses, hoping for the best, but upon placing them on your face you realize that your sunglasses lenses are smudged, scratched, and generally in need of a thorough cleaning. If you're like me then you're already frustrated and on the edge of a mini-meltdown. And the thought of having to make a new purchase isn't much better. But don't despair just yet - you might just be able to save your sunglasses!

Simple steps can be taken to clean your sunglasses lenses. Start by using lukewarm water and a bit of mild soap before drying with a soft cloth for best results.

Today's blog post will focus on the complete step-by-step guide to properly clean your sunglass lenses, saving you time and most importantly: money. So gather your supplies and let's get started!

Cleaning Solutions and Materials Needed

The cleaning solutions and materials needed for effective sunglass lens cleaning are important steps in the process, so special attention should be paid to what is used. Many people opt for just using water, but others believe a specialized cleaning solution specifically designed for cleaning lenses is best. Though these usually contain some chemicals, they are usually alcohol-free and can help reduce streaks and smudges from appearing after the lens is dried.

On the other hand, there are many people who choose to forgo any sort of cleaner or solution and use a microfiber cloth with just water to clean their sunglasses. This method is especially helpful when on vacation or traveling since it allows you to clean your lenses with whatever is already available. No extra materials or supplies are required, so it's often preferred by those who are trying to pack light.

Regardless of the path you take, having something to dry the lens off with afterwards is necessary. The microfiber cloth mentioned previously can work, but paper towels or even a clean t-shirt should do the trick as long as nothing abrasive comes in contact with the lenses. Knowing which type of material works best will help ensure you're taking proper care of your sunglasses during the cleaning process while avoiding potential damage to the lens finish.

Now that we have discussed which solutions and materials are needed for effective sunglass lens cleaning, let's move on to focusing more specifically on lens cleaners themselves in our next section.

Lens Cleaner

Lens cleaner is a product designed to offer extra protection against smudges and dirt. Lens cleaners can be found in liquid form or as wipes, depending on your preference. However, many ophthalmologists are often hesitant to recommend lens cleaners as it tends to cause more harm than good for people with sensitive eyes.

On one hand, proponents of lens cleaning solutions argue that the formula helps remove grease and dust that hasn’t yet been affected by body heat or water. These kinds of particles can be difficult to clean even with a microfiber cloth and mild soap solution. They say if you use these liquids extremely cautiously, they may help keep lenses looking spotless and clean.

However, opponents of lens cleaning solutions cite evidence demonstrating that over-use of these products can damage the anti-reflective coating applied to some lenses. In addition, lens cleaners may contain harsh chemicals which can irritate eyes or even interact with contact lenses negatively. It really depends on the individual's needs and their eye health history when determining whether or not lens cleaners are the best choice.

Lens cleaner is a product designed to offer extra protection against smudges and dirt, however careful consideration must be taken into account before use if an individual has sensitive eyes or wears contacts. It is always advisable to speak with your optometrist before deciding if lens cleaner is something suitable for you.

Now let's proceed onto discussing how one can safely disinfect fabrics and cotton rounds.

Disinfecting Fabrics and Cotton Rounds

When it comes to cleaning the lens of your sunglasses, two of the main tools to consider for disinfection are fabric and cotton rounds. Each material has its own unique benefits, so let’s discuss them in more detail.

Fabrics such as microfiber work great at collecting dirt and oils while not leaving scratches on the lens. For example, you could use a dry microfiber cloth to get rid of fingerprints and smudges. Alternatively, you could also use fabrics that have been dampened with warm water to pick up dust more effectively.

Cotton rounds have several advantages when it comes to weakly stuck oils and dirt that can’t be dislodged by fabrics alone. When used with an appropriate cleaning solution, they are great at collecting oil-based residue and filth even on the most intricate parts of the sunglass lens.

However, there is a risk when using cotton rounds since they may leave behind tiny pieces of material when rubbing against the surface of the lens which could scratch or damage it if not careful enough.

Both fabrics and cotton rounds are reliable tools when it comes to properly disinfecting your sunglass lens. The key is to find the right balance between them in order to ensure a thorough cleaning without risking any damage to the lenses themselves.

Now that we have discussed some tips on how best to sanitize our eyewear, let’s move on to tackling those pesky dirt and fingerprints that just won't seem to disappear no matter how often we clean our glasses!

How to Tackle Dirt and Fingerprints

Dirt and fingerprints are inevitable on sunglasses lenses, even when you're extra careful. Keeping your glasses clean every now and again is essential to maintaining that crystal-clear vision. To remove dirt and prints, start off with a simple cleaning solution.

You can use a commercial glass cleaner or make your own solution like warm water mixed with dish soap or alcohol. There is some debate over whether it's better to simply wipe the lenses clean with a damp cloth, or clean them using lens wipes specifically designed for eyewear.

Proponents of cloth wiping cite the ability to get in between the crevices of intricate frame designs whereas lens wipes cannot. The practicality of using a cloth—which is most likely something you already have on hand—instead of investing in special materials or tools adds an additional benefit over pre-packaged wipes. Not to mention, the textured surface of cloth helps remove stubborn smudges more effectively than wipes alone.

On the other hand, advocates of lens wipes argue that they are less likely to scratch the lenses than a cloth because they are made from soft microfiber materials and don't carry particles from previous usage like cloths do.

In reality, both methods can be successful depending on your preferences and the complexity of your sunglass frames. If you're going the cloth route, make sure it's dry (or only slightly damp) before wiping your lenses, as too much moisture can make eyeglasses smears hard to remove. Additionally, refrain from using paper towels as they have a rougher texture and may leave lint speckles on the glass.

No matter which method you choose for removing dirt and fingerprints from your sunglasses lenses, it’s important to take extra small steps to ensure you get all pesky grime from the tight spots between crevices. For frames with tight corners in particular, you may want to take extra care by switching to a glove or rubbing away at those spots with a finger before wiping down the surface.

 In any case, once the dirt has been dealt with then it’s time for one last cleanse for maximum clarity in order to ensure optimal vision quality as you move forward–both literally and figuratively speaking!

Rubbing Dirt Off with Cloth or Glove

In the face of stubborn dirt and fingerprints, some opt for a more gentle approach of rubbing them off with a cloth or glove. This is especially promising when smudged lenses lack heavy dust or build-up.

The advocate of this method would argue that rubbing the lens with a cloth can be done safely since it does not require the use of any chemical compounds. In addition, it saves time and energy as there are no special steps to follow or products to buy.

However, opponents would counter that this method should be done cautiously as the use of rigorous force can scratch the lens or push debris further into recesses where they cannot be removed easily. An additional concern is that the material used to wipe off the dirt might also leave residue behind or smudge the lens in different areas due to its fibers and texture.

It may be beneficial if one uses a microfiber cloth that is soft enough to not leave scratches and attracts dirt particles more effectively than other materials, such as cotton. To further protect your eyewear, consider using a cotton glove as an alternative. However, caution should still be exercised when rubbing dirt off with either cloth or glove so as not to damage the lens or push dirt deeper into its crevices.

No matter which approach you prefer in tackling dirt and fingerprints on sunglass lenses, oftentimes it takes additional effort beyond simply wiping them off. For those persistent smudges left behind, trying a natural solution may do the trick. From baking soda to toothpaste and even just plain water, these everyday items offer gentle yet thorough cleanings without being too harsh on you.

Wiping sunglass lenses with a cloth or glove can be a gentle and effective approach to eliminating dirt and fingerprints. However, care should still be taken as the use of too much force can scratch the lenses or push dirt further into their crevices.


To minimize damage, it is recommended to use a microfiber cloth or cotton glove and exercise caution during the process. If more thorough cleaning is required for persistent smudges, simple everyday items such as baking soda, toothpaste, and water can offer a natural solution.

Cleaning Smudges with Natural Solutions

When it comes to cleaning smudges, natural solutions are almost always preferred over harsh chemicals. Natural solutions like dish soap and olive oil can be a safer, more cost-effective way to keep your lenses as clean as ever.

Using a mild dish detergent, mix a small amount of liquid with warm water in a bowl or container. Submerge the lenses one at a time into the solution for about 30 seconds before gently rubbing them with a soft cloth or glove. Once both sides are cleaned, pat dry with another soft cloth and buff out the excess moisture. 

While some proponents argue that olive oil can be highly effective for removing smudges and dirt from lenses, others warn that it may provide short-term results but is not ideal for long-term use, especially considering the oil may cause discomfort if it gets into the eyes when worn. Ultimately, it’s important to weigh the pros and cons of each cleaning option before making a choice.

After dusting and wiping away smudges, it might be necessary to remove scratches that occur on the surface of the lens or residue left behind from sunscreen products. Ultimately, this will require an extra level of care and attention to ensure proper cleaning and maintenance of sunglasses lenses.

How to Remove Scratches and Sunscreen Residue

Removing scratches and sunscreen residue from sunglasses lenses presents a unique set of challenges. For starters, lens coatings, such as anti-reflective treatments and mirror coating, can be damaged by incorrect cleaning methods. This means that many standard cleaning techniques – such as wiping the lens surface with rubbing alcohol or using a tissue to rub dirt from the lens surface – must be avoided.

Fortunately, there are some scratch-removal products available on the market that can be effectively used to treat scratched sunglasses lenses. Such products typically contain a mild abrasive formula designed to gently buff away small scratches while not damaging the protective coatings on the lens surface.

These products should always be applied with a soft microfiber cloth and gently worked in circles across the entire surface of the lens. The product should then be removed by first wiping off any excess with a clean portion of the microfiber cloth and then rinsing with water to remove any remaining residue.

Sunscreen residue can also be difficult to remove from sunglass lenses because it can form an invisible "film" on both sides of the lens that cannot be seen until inspected closely under bright lighting conditions. In this case, special glasses cleaning wipes containing specific ingredients meant to break down sunscreen residue work best.

Again, these wipes should always be used sparingly and gently worked over both sides of the lens using a microfiber cloth for best results. After applying and massaging in the wipes, all remaining residue should be removed by once again rinsing with water and then drying with a soft microfiber cloth.

In general, every cleaning effort should involve testing on an inconspicuous corner of either lens first before applying elsewhere. Patience is also essential when attempting to remove scratches from sunglasses lenses and when trying to correctly identify the cause of any smears; avoiding common cleaning mistakes like "scrubbing" too harshly or allowing product residues to settle into grooves around screws on temple arms can often result in higher success rates when dealing with these two particular types of issues.
