The lens design depends on the type of correction you need and your daily activities.

According to use

  • Single vision lenses: For just one prescription, distributing focus evenly over the entire surface of the lens.
  • Ocupational lenses: Utilize progressive power optics and are designed primarily to meet near and intermediate viewing needs such as working at a computer workstation for presbyopic patients.
  • Progressive lenses: For people who have presbyopia and need various correction areas, providing clear, relaxed vision at all distances.

Types of Progressive Lenses

  • QUALITY: Comfort in any situation. Optimal vision and adaptation thanks to its internal free form design. Ideal for users who want a progressive lens with clear vision at all distances and a wide area of closure without sacrificing a good price.

Unrivaled performance and optical characteristics.

02. Materials

Different materials have different refractive indexes. The higher the index, the thinner and lighter the lenses are and also, more comfortable to wear. Our lenses are manufactured in three different materials:

Organic Lens

  • This is a high quality material that has a lower density and allows your glasses to be lighter and more comfortable.

Mineral Lens

  • A very hard and scratch resistant material, but thanks to properties such as low weight and high breaking resistance, plastic lenses have gradually overtaken ore lenses.

Polycarbonate lens

  • Polycarbonate lenses are ultra durable and ultra light lenses. They are more than 10 times more resistant to impacts than their average plastic or glass lenses. With the right coating or scratch resistant, their potential increases even more. Therefore they are recommended for sports and children.

03. Lens Treatment

Coating adds specific features to the lenses, making them anti-reflective, scratch-resistant, colored or contrast-enhancing:

Anti-reflective coating

  • In addition to blocking  brightness and sparkle, avoid the adherence of dust, fingerprints and even drops of water on the lenses … reducing the chances of the lens getting dirty and scratchy.

Scratch Resistance

  • Choosing the hardest coating, provides you with long lasting scratch resistance, which remains almost intact, even after intensive cleaning.

Blue Zero

  • The specific anti-reflective for digital screens. Protect your eyes from digital devices, blocking up to 20% of harmful blue light.

Other options

  • Polaroid: It neutralizes uncomfortable reflections and the high luminosity that come from surfaces such as wet roads, water or snow … and guarantees a vision rich in contrasts.Highly recommended in sunglasses.
  • Photochromic: It makes the lenses adapt to the ambient light. It allows you to wear the same glasses throughout the day without having to change them every time you enter or leave a site.

Did you ever wonder?

04. Frequent Doubts

What are the advantages of reduced thickness lenses?

  • They weigh less and therefore they are more comfortable. They also have aesthetic advantages since they reduce the thickness of the glass that bothers so much in high prescriptions.

Is it difficult to adapt to progressive lenses?

  • No, adaptation to progressive lenses is usually quick. It depends on the progressive design you choose. If you choose a custom design, in accordance with your prescription, physiognomy and adapted to the characteristics of the chosen frame … the adaptation will be immediate.

The use of phones, tablets and computers.

  • The world is increasingly digital and most of us use digital devices from morning till the end of the day.. For example, laptops, tablets, phones and televisions … Due to the short distance between us and these devices, we are increasingly exposed to the light emitted by the screens. In addition, our eyes make a great effort to have to alternate constantly between photos and texts. Adults spend between 4 and 6 hours a day in the use of digital devices, while 14% spend between 10 and 12 hours a day. Therefore it is unsurprising that more and more people suffer from discomfort such as:
    • Red and irritated eyes
    • Dry eyes
    • Blurred vision
    • Fatigue
    • Back, neck and shoulder pain
    • Headaches

Blue light

All computers and LCD and LED screens, mobile phones, tablets and GPS devices emit blue light, also known as high-energy visible light. With the improvement in the quality of the screens, their blue light emissions increase. Although blue light itself is a natural phenomenon (it is present in sunlight and helps keep us awake), overexposure can cause adverse effects such as fatigue and visual stress.

  • Our iBeslayt lenses neutralize the harmful blue light emitted by digital screens, preventing fatigue and visual stress. They keep the eyes in better condition while offering greater comfort, visual relaxation and a more natural perception of color in the daily use of digital devices.
