Top 10 Photochromic Lenses

The range of the French manufacturer now includes photochromic lenses to protect the eyes from the bright sun, made using Transitions VII Signature technology. They strike a balance between outdoor shading, indoor transparency, and high responsiveness to light changes. Recommended for wearing throughout the day. In addition to the classic colors (brown, gray, gray-green), the company offers trendy colors - sapphire, amethyst and amber.

Moreover, the above options can be combined with mirror finishes from a palette of 18 positions. It's inspired by the Ray-Ban sunglasses collection and when paired with spectacle frames, it maximizes your style options.

The Israeli company Shamir is one of the top ten world manufacturers of spectacle lenses. Its own network of 16 laboratories and global investments in research and development allow it to produce eye products with the most advanced technologies. Shamir products are quite expensive, but the Altolite 1.5 photochromic lens is offered at an affordable price and pleases with unsurpassed brand quality. Made of polymer optical material CR-39, the most resistant to abrasion and scratches.

Darkening characteristics are optimal: outdoors at 23° - 90%, in a car at 27° - 50%, residual darkening in the room does not exceed 12%. The lens surface is modified with a multi-layer anti-reflex coating Hard Multi Coat.It includes strengthening, anti-reflective and hydrophobic layers, which together provide the most aesthetic appearance of glasses and visual comfort during long-term wear.

The lenses are unique in that they are able to precisely adapt to lighting conditions and automatically darken exactly to the stage that is needed. The effect is due to the unique technology of Chromea 7 - embedding special pigments into the surface. They are composed of trillions of molecules, the shape of which constantly and smoothly changes depending on the light. When the structure changes, the lens darkens or brightens to the desired degree.

Thanks to Chromea 7, the lenses respond better to side light reflected from buildings, cars, as well as penetrating through clouds and treetops. The creators of the innovation claim that they personally tested their lenses daily under various weather conditions. All the factors that arose in more than 200 real situations and 1000 worked out scenarios were taken into account and taken into account by the design. According to research conducted by an independent company in 15 countries, out of 4,000 users of Nikon Transitions, 90% are ready to repurchase them.

Lenses designed specifically for active people. In the bright sun, they darken by 90%, which is the best indicator compared to all other models. This is a spherical plastic lens with diopters from -10 to +8.75 and a cylinder from -4 to +4.It is single vision and very thin - a refractive index of only 1.67. There is also a spherical version, but it is noticeably thicker (IP is only 1.5). There are two colors on sale - brown and gray.

There is a multifunctional multi-layer coating HMC, which has several properties at once. It eliminates glare, repels moisture and dirt, has anti-static properties and is incredibly durable. Manufacturers have made sure that the model can also be used in a car - it is darkened by 50%, so now driving will become noticeably more pleasant even in sunny weather. But it is worth remembering that the initial darkening of such a lens is 11%, so the shade will be visible even indoors.

Inexpensive, but high-quality photochromic lenses made of organic polymer. German quality pleased here too. For a reasonable price, you can get good mid-range lenses. Able to provide dimming up to 85% in bright light. Indoors, they do not become completely transparent - the residual effect retains about 8% dimming. The lens is not the thinnest, the refractive index is only 1.54. But the polymer material made it possible to make it thinner than plastic and even more so glass counterparts.

The diopter range is frankly small - only from -6 to +4. There are two diameters - 65 and 70 millimeters. Available in two standard colors - brown and grey. The lenses themselves are coated with one of two options: SPP or Duralux. The first is a nanotech coating with many functions, from anti-reflective to dirt-repellent and strengthening. Duralux simply makes the surface more durable and resistant to physical damage.I am glad that the lens quickly responds to changes in illumination - it takes several tens of seconds for it to change color.

The higher the degree of nearsightedness or farsightedness in a person, the more important it is for him to choose aspherical lenses. Carl Zeiss 1.6 AS PhotoFusion is a great option. They remain thin even at optical power of 5-10 diopters, look beautiful in any frame, do not distort the size of the eyes and do not violate the proportions of the face. The optical properties are also good: there are no visual aberrations, the field of view remains wide.

Lenses are made of polymeric material MR-8. Unlike CR-39 lenses, they are 25% lighter and thinner and completely block out UV radiation. They are coated with a 9-layer proprietary DuraVision Platinum coating, due to which scratch resistance is increased, a hydrooleophobic layer appears. Another layer prevents static electricity from accumulating on the surface, thereby preventing dust from settling. Thanks to this manufacturing technology, the lenses stay clean longer.

The manufacturer tried to make really high-quality and versatile photochromic lenses. And the French did it. This is a strong, thin and light lens that can easily save your eyes from excessive UV radiation. It is made of impact-resistant polycarbonate treated with a special Crizal Alize + UV coating.It gives the surface many useful characteristics - it is perfectly smooth and transparent, it is easy to clean it from dirt. An important feature is that dust and dirt will not linger on the lens, so you will have to clean it less often.

This particular photochromic spherical model is single vision, you can purchase options from -12 to +7.75 diopters. In addition, it is easy to pick up a cylinder - from -6 to +5.75. The lens has a refractive index of 1.59 - it can not be called the thinnest, but it looks quite aesthetically pleasing. The choice of the manufacturer provides two shades - gray and brown. In bright light, they darken up to 88%. But in fact, the lenses will have a slight greenishness even in poor light. I am glad that the manufacturers have provided the opportunity to use them when working at a computer due to the increased contrast of the image and in the car (even at night).

Large, highly curved frames are best fitted with lenses with a high base curvature. Seiko Optica offers a photochromic model with the latest High Curved Technology. Its asymmetrical-aspheric design provides the user with a wide, clear, aberration-free view across the entire surface. The price includes SuperClean Coat multi-coating of 16 layers: hardening, anti-reflective, water and dust repellent, etc.

Optionally, it is possible to order the Mirror coating in one of 5 shades - gold, silver, blue, red or green. Also, on request, you can cover the lens with a layer of "Blueblocker", which filters blue radiation from PC screens, smartphones, TVs.At the same time, the color reproduction remains natural, and the high refractive index n=1.67 makes the glasses thin and elegant.

Japanese quality especially for drivers. These photochromic resin lenses were created for those who spend a lot of time behind the wheel. They have everything you might need on the road - a high-quality polarized coating and a sensitive photochromic coating that can change the degree of darkness in a matter of seconds. The color changes very gently from light yellow-green to rich brown, the maximum darkening is up to 85% outdoors. In the car, the lenses will only be darkened by 50% to create a comfortable driving environment.

The lens is single-focus, manufacturers provide diopters from -9 to +7.5, but, unfortunately, the cylinder is not provided. Only one color, branded green-brown. But there are as many as three coating options - HVA (reflective and dirt-repellent), SHV (strong and reflective) and HVLL (a combination of the two previous ones with increased strength). All three variants are slightly greenish (up to 25%) even in the absence of darkening factors. Taking into account the polymer material, the lens of moderate thickness has a refractive index of 1.5. An important clarification is that glasses can only be used during the day, they are not suitable for night driving.

Drivewear Crizal Easy lenses are the best accessory for drivers because they combine 3 functions in one product at once: vision correction, eye protection from annoying reflected light (polarization) and darkening / brightening depending on lighting conditions. The unique combination of technologies allows them to be used both outdoors and in the car as effective sunglasses.

The optics are made of polycarbonate, which belongs to materials with an average refractive index. Compared to lenses made from other polymers, Crizal Easy is flatter, lighter and thinner, and eyeglasses look attractive with them. In addition, polycarbonate can withstand 10 times the impact load, so it is considered the safest for the eyes.
