Photochromic Lenses

Photochromic lenses are a wonderful innovation for those who wear glasses. They are designed to automatically adapt to changes in light, offering you comfort and protection at any time of the day, regardless of the weather.

Photochromic lenses, also known as transition lenses, are special lenses that change color depending on UV rays and the temperature to which they are exposed. In other words, indoors or in low light conditions, they are transparent, while outside, in the presence of UV rays, they darken like sunglasses. The time it takes for photochromic lenses to change color can vary from a few seconds to 2-3 minutes, and when they are no longer exposed to UV radiation, the lenses gradually return to their transparent state.

Any photochromic lens is influenced by temperature. When the temperature is lower, photochromic lenses darken more and lighten more slowly. When the temperature is higher, the lenses do not darken as much but lighten faster. This is a characteristic of the photochemical structure of the lens. The photochromic molecules use thermal energy to darken and lighten the lens.

Who are these lenses recommended for?

  • Those who have undergone eye surgery.
  • Patients with diabetes cataracts, which affect contrast and night vision.
  • Those who suffer from photophobia and have an active lifestyle, frequently transitioning between indoor and outdoor environments.
  • Patients with lighter eye colors (green or blue).

Benefits of Photochromic Lenses

  • Continuous UV Protection: photochromic lenses effectively filter UV rays, protecting the eyes in any light conditions.
  • Light Adaptability: these lenses automatically adjust based on UV rays and temperature, becoming dark outside and transparent indoors, ensuring visual comfort in any environment.
  • One Set of Glasses: eliminate the need to switch between prescription glasses and sunglasses, saving time and money.
  • Reduced Eye Strain: the anti-reflective coating applied to photochromic lenses reduces eye strain caused by artificial light.
  • Variety of Colors and Frames: available in a wide range of colors and styles, these lenses can be customized to suit your aesthetic preferences.

Available Colors

Photochromic lenses are available in various colors, each with specific properties. The most common are:

  • gray: gray photochromic lenses are the most popular as they offer a natural perception of colors and reduce light intensity without distorting the colors of surrounding objects. People with myopia also prefer gray lenses;
  • brown: brown lenses have a warm and pleasant appearance, being a popular choice for those who want a more sophisticated and natural look;
  • green: green lenses have a modern look and are often associated with a classic and elegant style.

UltraChrome Photochromic Lenses

The UltraChrome photochromic treatment protects you from harmful UV rays, offering the comfort of a pair of sunglasses. The advantage of these lenses is that you can use them even when there is not strong sunlight outside, as they darken according to the intensity of the UV rays, having the right tint for any situation.

If you choose UltraChrome lenses together with the Satin anti-reflective coating, you will also eliminate the problem of reflections that occur in artificial light without needing to wear multiple pairs of glasses. Unlike other types of photochromic lenses, UltraChrome lenses do not darken as much, making them suitable for people who do not want a pair of photochromic lenses that are too dark.

Transitions and Transitions Xtractive Photochromic Lenses

Transitions photochromic lenses offer a wide range of colors for UV protection, with an indoor light transmission of 5% and a maximum darkness of 85%. Besides the usual colors, fashionable colors are also available, such as Emerald, Sapphire, Amethyst, and Amber.

Transitions Xtractive photochromic lenses darken even behind the windshield. Unlike regular Transitions, they are a few percent darker depending on the chosen color, both outdoors and indoors. They are recommended for drivers who spend a lot of time at the wheel or for people with increased sensitivity to natural light.

NeoChromes Photochromic Lenses

NeoChromes lenses help wearers take care of their eyes by providing 100% protection against harmful rays. They also filter blue light, especially when activated in natural light.

UV Blocking

UV rays are invisible with wavelengths between 100-380nm. Exposure to UV rays can cause changes in the skin such as tanning, but it can also cause burns, wrinkles, or even some forms of cancer. The cornea and lens of the adult eye are effective in blocking harmful UV rays, thereby protecting the retina. However, these UV rays can damage the skin and the structure of the eye. Prolonged exposure to UV rays is closely linked to the onset of pterygium, photokeratitis (snow blindness), cataracts, or other eye conditions. NeoChromes lenses block 100% of UV rays up to a wavelength of 400nm.

UV Filtering

Blue light is part of the visible light spectrum with wavelengths between 400-500nm. The sun is by far the largest source of natural blue light. PC screens, phones, or other digital devices are also a source of blue light. NeoChromes lenses provide maximum protection against these harmful light waves. NeoChromes gray lenses block about 80% of this light (400-420nm) when the lens is transparent and up to 91% when it is dark. Additionally, they block 89% of light when it is cloudy.

Photochromic lenses: protection and comfort at all steps

Photochromic lenses are an excellent choice for anyone who wears glasses and wants added comfort and protection. Regardless of your style preferences or specific eye protection needs, there is a pair of photochromic lenses that will suit you perfectly. Take advantage of the latest technology for clear vision and optimal protection every day!
