Sunglasses are an important accessory in the summer months, as they protect our eyes from UV rays and help prevent eye strain, headaches and other conditions. To properly protect your sunglasses and extend their life, we prepared some simple tips for you to keep your sunglasses in great condition for years to come:

What are these sunglasses made of?

Sunglasses frames are typically made from plastic, metal, or wood. Plastic frames are often the most lightweight and practical option for outdoor activities, as they are resistant to heat, moisture, and abrasion. Metal frames are usually more durable and can be designed in many shapes and sizes. Wooden frames offer a unique look but need extra care due to their fragile nature.


Plastic sunglasses are lightweight and comfortable to wear for extended periods of time. They are usually cost-effective and come in a variety of shapes, styles, and colors. However, plastic is not as durable as metal or other materials and can be easily scratched or warped from exposure to heat or moisture.


Metal sunglasses are more durable than plastic and can withstand heat and moisture without warping or scratching. However, metal frames are usually more expensive than plastic and can be uncomfortable to wear for extended periods of time due to their heavier weight.


Wooden sunglasses offer a unique, natural look and can be stylish, lightweight, and comfortable to wear. They are also biodegradable and eco-friendly. However, wooden frames are more expensive than plastic or metal, and their light weight makes them less durable against heat or moisture, which can cause warping or crack over time.


What will damage to the material of sunglasses?

Sunglasses can be damaged by exposure to heat, moisture, and pressure. Extreme temperatures can cause the frames to warp or crack, while high humidity can cause them to become brittle and break easily. Pressure on the frames—such as twisting or bending—can also cause damage.

How to store sunglasses

1. Avoid exposure to sunlight and heat

Shielding your sunglasses from direct sunlight and intense heat is an important step in keeping them looking and performing their best. Avoid leaving them in direct sunlight in a car or on other hot surfaces, as this can cause the lenses and frames to warp or change color. When not wearing your sunglasses, be conscious of their placement - try not to leave them on top of head units or near windows for extended periods of time.

2. Avoid exposure to moisture

Exposure to moisture can be very damaging to sunglasses, leading them to become warped after long exposures, and without proper care, they'll quickly break down. Keep your sunglasses out of hot cars, away from the beach, and use a hard case for storage when not in use - this will go a long way towards protecting them from moisture and ensuring that you can enjoy their protection all year round.

3. Place them in cases when not in use

To keep them in good condition, place them in soft cases when not in use. Doing so protects the frames and lenses from getting scratched and damaged, helping guard against dust and moisture getting onto the lenses. Not storing sunglasses in cases also increases the likelihood of losing them, or having them crushed or broken when carried around in a bag or purse. So, no matter how much you may love sunglasses and like to flaunt them out and about, always make sure to place them back in protective cases once they aren't being used.

4. Clean the lenses regularly

Finally, cleaning the lenses regularly with a microfiber cloth will help maintain their clarity and improve your vision. You should also clean them regularly with a lens cloth to remove dirt, dust, or other particles that can scratch the lenses or impair their clarity. Make sure not to place your glasses on paper towels which can cause damage.

How to refresh sunglasses

To refresh your sunglasses, start by cleaning the lenses with a microfiber cloth. Then, if there are any scratches or smudges on the lenses, use an optically safe lens cleaner to make them crystal clear. Finally, inspect the frames for any signs of wear and tear such as cracking or warping and apply a small amount of lubrication to any squeaky hinges.
