Our sunglasses are handcrafted from the highest quality cellulose acetate, sourced from the world’s leading supplier in Italy. Cellulose acetate is a plant-based plastic meaning its hypoallergenic, lightweight and very strong. Our metal frames are manufactured from high-quality stainless steel. Stainless steel is lightweight, flexible, strong and corrosion-resistant offering maximum durability and increased comfortability.

Our lenses are either crafted from CR-39 or Nylon, lightweight materials that offer an extremely high optical quality, almost as good as glass. In terms of durability, both CR-39 and Nylon are incredibly scratch and shatter resistant. 

Yes, all of our lenses offer 100% protection against UVA and UVB rays.

We do not currently offer prescription lenses. However, all of our lenses can be replaced with prescription lenses by your local optician.

Yes, all of our sunglasses have been designed so that they can be easily adjusted to your individual needs. If your find that your acetate frames are too tight or loose, crooked on your face or hurt your ears, your local optometrist will be able to make the necessary adjustments. For metal frames, simply tighten or widen the nose pads. If, over time, the glasses become loose you can tighten the hinge screws with a small screwdriver. Again, these adjustments can be made by your optometrist.

Store your sunglasses in the case provided in a dry place at a temperature between -10°C and +35°C. Avoid putting them face down on any surface as this may scratch the lenses.

To maintain the function of your sunglasses we recommend regularly cleaning the lenses with soap and water. Avoid the use of any solvents of alcohol. When drying, use the microfibre cloth provided and avoid the use of abrasive cloths as these may damage the lenses.

At DMY BY DMY we take great pride in the craftsmanship of all of our sunglasses. In the unlikely event that a defect in materials or workmanship is found in your sunglasses within twelve months of purchase, we are happy to exchange it with proof of purchase. Please note, our warranty does not cover sunglasses that have been altered, personalised or damaged due to normal wear and tear.
