Types of lenses for prescription eyewear include single vision lenses, bifocal lenses, progressive lenses, toric lenses, and prism lenses, all which have their own unique purposes. Choosing the right lens is essential to corrective eyewear so your vision can be corrected safely and correctly. Bifocal glasses have lenses for correcting both near and far-sighted vision, mineral photochromic cam, with a dividing line down the middle.

Etnia Barcelona eyewear is bathed in beautiful colors drawing attention to their amazing craftsmanship. At that time, eyewear collections were mostly black or brown and color was not an important factor to manufacturers. Etnia Barcelona is color, art, culture. It is mediterranean, independent and rebel. It is tradition and modernity. It is quality and innovation. And it is also the city that inspires us: Barcelona.

Mineral photochromic lenses are a revolutionary category of eyewear technology designed to provide both comfort and convenience. These lenses intelligently adjust their tint based on the intensity of UV radiation, offering clear vision indoors and automatically darkening to protect your eyes when you step outside. At the core of mineral photochromic lenses lies a dynamic material composition. These lenses are crafted from special silicate glass embedded with silver halide crystals. When exposed to UV light, these crystals undergo a chemical change, causing the lenses to darken. This transition helps to shield the eyes from harmful UV rays and reduce glare. There are various types of photochromic lenses available, but mineral glass photochromic lenses stand out for their durability. Unlike their plastic counterparts, mineral lenses are more scratch-resistant. Consumers can find these lenses in a range of colors and index options, catering to different prescription strengths and aesthetic preferences. Mineral photochromic lenses are particularly beneficial for individuals who frequently move between indoor and outdoor environments. They eliminate the need for a separate pair of sunglasses, making them a practical choice for everyday wear. The adaptive tint technology also means enhanced visual comfort, as it reduces eye strain caused by sudden changes in light. These lenses are not only user-friendly but also environmentally conscious. The photochromic technology in mineral lenses is designed for repeated use over a long period, reducing the need for multiple pairs of glasses. Their resilience to scratching and ability to revert back to their original state after the absence of UV light make them a sustainable choice.

Materials able to respond to external stimuli have garnered interest in a variety of research areas. In this context, the chromic materials have been considerably focused for designing devices for multiple applications. Photochromism can be described as a reversible conversion of a chemical species between two isomeric forms caused by electromagnetic radiation absorption, resulting in a color change Reis et al. Figure 1A shows the evolution of publications over the years considering the keyword photochromism on the Scopus website. Based on the recorded data, Figure 1B shows that the two areas with the highest number of publications include chemistry and materials science. A Number of publications per year and B distribution areas of publications based on the Scopus database records.
