Etnia Barcelona eyewear is bathed in beautiful colors drawing attention to their amazing craftsmanship. At that time, eyewear collections were mostly black or mineral photochromic cam and color was not an important factor to manufacturers. Etnia Barcelona is color, art, culture. It is mediterranean, independent and rebel.

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, with a dividing line down the middle. Progressive glasses are becoming increasingly popular as they correct vision at near, middle, and far without a visible divide. When it comes to glass types, polycarbonate lenses are the most durable and impact-resistant, making it a great choice for children or people who spend a lot of time outdoors or engaged in physical activity. For those without the need for vision correcting but would still like a way to protect their eyes, blue light filtering glasses and blue light reading glasses are a great way to filter out the blue light emitted from digital screens. Many of us who spend all day in an office staring at a monitor or phone screen need a way to protect our eyes from the harsh light.

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.

Fluorescent molecules and materials are widely used in many areas in physics, chemistry, and biology as emitters, tags, or sensors. The possibility of controlling their fluorescence signal by light, namely, fluorescence photoswitching, down to the nanoscale level can then dramatically extend their fields of applications. This review focuses on fluorescent and photochromic diarylethene-based nanosystems.

Photochromism is a phenomenon described as a reversible conversion of a chemical species between two isomeric forms, induced by the absorption of electromagnetic radiation, which results in color changes. Isomerization of organic photochromic molecules involves chemical processes such as: pericyclic Keywords : photochromic materials, stimuli-responsive material.

Purely organic photochromic materials, which can undergo photo-induced reversible switching between two isomers, have received enormous attention in the last decade, due to their distinct features of high photosensitivity, excellent fatigue-resistance, etc. The improvement of existing photochromic materials and exploration of new molecular systems have largely extended their applications to energy-conserving coatings, ophthalmics, and optical memory devices and switches.
