Reasons Why Sunglasses Always Get Dirty

There are several common reasons why Sunglasses Always Get Dirty, including natural oils from your skin and hair, sweat and water droplets, dust and debris from the environment, fingerprint smudges, makeup residue, and poor storage or handling.

Let’s discuss them in detail!!

Sunglasses Always Get Dirty

The Natural Oil from Skin and Hair

One of the most common reasons why Sunglasses Always Get Dirty is due to the natural oils present on your skin and hair. Every time you wear your sunglasses, these oils transfer onto the lenses, creating a greasy film that can be difficult to remove. 

This is especially true if you have oily skin or hair. Over time, the buildup of natural oils can make it hard to see through your sunglasses.

Sweat and Water Droplets

Sweat and water droplets can also contribute to dirty sunglasses, especially if you wear them while exercising or in humid environments.

When these droplets dry on the lenses, they can leave behind streaks and watermarks that can be difficult to remove.

Dust and Debris from the Environment

Dust and debris from the environment can also accumulate on the lenses of your sunglasses, making them appear dirty and cloudy. This is especially true if you live in a windy or dusty environment.

Fingerprint Smudges

Fingerprints are another common culprit for dirty sunglasses. When you touch the lenses with your fingers, you leave behind oils and debris that can create smudges and streaks.

Makeup Residue

If you wear makeup, it can easily transfer onto the lenses of your sunglasses, leaving them dirty and greasy. This is especially true if you apply makeup around your eyes.

Poor Storage or Handling

Lastly, poor storage or handling of your sunglasses can also contribute to them getting dirty. If you toss your sunglasses into your bag or leave them lying around, they are more likely to accumulate dust, debris, and scratches.

Prevention of dirty sunglasses

Cleaning them regularly with a Microfiber Cloth or Lens Cleaner

Regular cleaning is key to preventing dirty sunglasses. Use a microfiber cloth or lens cleaner to gently wipe the lenses clean. This assists in cleaning the lenses by removing fingerprints.

Avoid Touching the Lenses with Your Fingers

Try to avoid touching the lenses with your fingers, as this can transfer oil and dirt to the lenses. Instead, use the sides of the frame to put on and take off your sunglasses.

Avoid using Harsh Chemicals or Materials that can Scratch the Lenses

Avoid using harsh chemicals or materials that can scratch the lenses, such as paper towels or rough fabrics. Instead, use a microfiber cloth or lens cleaner specifically designed for sunglasses.

Store Them in a Protective Case When Not in Use

When you’re not wearing your sunglasses, store them in a protective case to prevent them from getting scratched or dirty. This will also help keep them safe from accidental damage or impact.

Avoid Exposing Them to Extreme Temperatures or Environments

Exposing your sunglasses to extreme temperatures or environments, such as leaving them in a hot car or near a heat source, can cause damage and make them more prone to getting dirty. Similarly, avoid wearing them in dusty or dirty environments or when you’re sweating heavily.

Choose Sunglasses with Protective Coatings

Certain sunglasses have layers of protection which render them less susceptible to dirt, dust, and smudges. Look for anti-reflective or hydrophobic coatings on sunglasses to repel water and other liquids.


In conclusion, dirty sunglasses are a common issue that can be caused by a variety of factors mentioned above.

However, there are various precautions that can be taken to maintain your sunglasses clean and in good shape. 

You can keep your sunglasses looking like new for longer by cleaning them frequently with a microfiber cloth or lens cleaner, avoiding touching the lenses with your fingertips, preventing harsh chemicals or substances that can scratch the lenses, keeping them in a case with protection when not in use, and avoiding revealing them to extreme temperatures or environments.

Your sunglasses are able to protect your eyes while improving your look for years to come with proper care and maintenance.

 So take care of your sunglasses and enjoy the benefits they provide.
