Our glasses
It is recommended to wear reading glasses when you have difficulty seeing nearby objects clearly, such as books, newspapers, computer screens, mobile phones, etc. This may manifest as symptoms such as headaches, eye strain, blurred vision, pain or tension around the eyes, difficulty focusing on nearby objects, difficulty reading for long periods of time, etc. If you are 40 or older, you may need reading glasses, as this is generally the age when presbyopia begins to develop. Presbyopia is a vision condition that makes it more difficult to focus on nearby objects. It is important to consult an optometrist or ophthalmologist for a comprehensive eye examination if you think you may need reading glasses. They will be able to determine whether you need reading glasses and which prescription is most suitable for you.
All our reading glasses and polarized sunglasses for adults are designed in the South of France, near Saint-Tropez. They are then made in Taiwan by a small family business. We have worked with the same company since Maison K-Eyes was founded in 2004. Why Taiwan? We chose this small island for its expertise, high quality standards, and the innovative materials and cutting-edge technology available at highly competitive prices.
It has always been essential for our small French company to offer unique, well-designed, and affordable frames to accompany you every day.
Most of our frames are made from injected polycarbonate. This is a lightweight, comfortable material for everyday wear that is highly resistant to impacts and scratches.
Our children's sunglasses, on the other hand, are made from BPA-free TPEE (thermoplastic elastomer). TPEE is a recyclable, non-toxic, hypoallergenic material that is safe for children. It is also soft, flexible, and impact-resistant, making it ideal for outdoor activities and play.
You can find a detailed list of the materials used in our glasses on each product page under the “Technical Specifications” tab.
Single-vision For seeing up close. These lenses have scratch- and smudge-resistant coatings.
Bifocal or double-vision For seeing up close in the sun with just one pair of glasses. They have scratch- and smudge-resistant coatings.
Blue Light Protection To protect your eyes from screens. They are available with or without prescription lenses and filter approximately 40% of blue light.
All our optical lenses are BPA-free acrylic. This material provides excellent optical clarity and high impact resistance.
Polarized sunglasses lenses made of BPA-free acrylic. Our polarized lenses feature anti-glare, anti-scratch, and anti-smudge treatments, as well as Category 3 UV400 protection to protect your eyes from 100% of UV rays. They reduce glare while enhancing contrast.
Sunglasses lenses made of BPA-free cellulose triacetate. Our sunglasses lenses feature Category 3 or Category 2 UV400 protection. To find out which type of lens is used, click on Technical specifications on each model’s page.
To keep your glasses in perfect condition, store them in their case when you are not using them. Keep them in a dry place at room temperature, away from heat sources.
Clean the lenses with clean water. Gently wipe the lenses with a soft, clean, dust-free cloth to avoid scratches.
To clean all or part of your glasses, never use detergent, solvent, hydrocarbons, or corrosive products.
Order
To determine the diopter strength you need, simply take a diopter test. Download the test available on each product page, then try to read the texts from a distance of about 30 cm. Each text corresponds to a diopter strength, and yours will be the one corresponding to the text you can read without difficulty. Nevertheless, always try to choose the lowest diopter strength among those that suit you.
Here are some tips for finding out your diopter strength:
- Use your old reading glasses or those of someone close to you and take a reading test. Note: you will find the corresponding prescription inside the temples of the glasses.
- You will find your prescription on your ophthalmologist's prescription. If your ophthalmologist prescribed you glasses for presbyopia, they will have indicated a positive number ranging from +1 to +3.5.
- You can also follow the recommendations generally made by presbyopia specialists:
+1 ≃ 40 years old
+1.5 ≃ 45 years old
+2 ≃ 50 years old
+2.5 ≃ 55 years old
+3 ≃ 60 years old
+3.5 ≃ 65 years old and over

We recommend checking the dimensions of the glasses you are interested in by clicking “Technical specifications,” available on each product page. There, you will find the dimensions of the frame and lenses to help you make your choice based on your face shape. Feel free to measure your face as well. The bridge width varies from one pair to another. Choose a narrow bridge if you have a fairly slim nose. “Oversized” frames are inherently larger than others and may, for example, be less suitable for small, narrow faces. We provide detailed descriptions of each model to give you as much information as possible and help you make your choice.
You can return most of our collections free of charge (excluding Great Deals, sale periods, and Flash Sales) if you are in mainland France. This means you can easily try the glasses on at home and return the pair that is not suitable.
If you are having trouble choosing your glasses, you can visit one of our retailers’ stores. Go to the Stores page to access the list of our points of sale. We work with retailers all over the world!
