Each of the materials used in making lenses has its own refractive index, which determines their thickness. Standard lenses have an index of 1.50 and from there, the higher the index the smaller and thinner the lens will be.

They weigh less and are therefore more comfortable to wear. They also look better because the lenses are not too thick, which can be an issue with high prescriptions.

No, you usually adjust to progressive lenses quite quickly. It depends on the design of progressive lens that you choose. If you choose a bespoke design, adapted to your prescription and facial features and the features of your chosen frame, you’ll get used to them in no time.

The world is becoming more and more digital and most of us use digital devices from the moment we wake up until the time we go to bed, for both work and leisure. For example laptops, tablets, mobile phones and TVs, among others.

We are also becoming steadily more exposed to the light emitted by the screens because of how close we are to the devices when we are using them. Our eyes also have to strain significantly to cope with alternating continually between photos and text. Adults, on average, spend 4 to 6 hours every day using digital devices, and 14% use them for 10 to 12 hours each day. Therefore, it is no surprise that this is leading to an increasing number of physical problems, such as:

  • Red and sore eyes
  • Dry eyes
  • Blurry vision
  • Fatigue
  • Back, neck and shoulder pain
  • Headaches

Blue light

All computers, LCD and LED screens, mobile phones, tablets and GPS devices emit blue light, also known as high-energy visible light. As the quality of these screens is improving, their blue light emissions are also increasing. Although blue light in itself is a natural phenomenon (it is found in sunlight and helps to keep us awake), overexposure can lead to adverse effects, such as fatigue and visual stress.

Our iBeslayt lenses neutralise the harmful blue light emitted by digital screens, thus preventing fatigue and visual stress. Keep your eyes in better condition while simultaneously increasing comfort and creating a more relaxed vision and a more natural perception of colour in the daily use of your digital devices.
