Special lenses with a filter for blue radiation They can be placed on any frame you want. 
They are used by people who already wear glasses with some correction (myopia, farsightedness, astigmatism), but also by all those who do not wear corrective glasses and want to protect their eyes from fatigue and from problems that may arise due to the long-term use of LED screens. 
Such problems include macular degeneration, a serious condition that causes irreversible eye damage. 

How polarized glasses work:

The bright light that is reflected from the various surfaces causes us a blur and intense discomfort. This light enters our eyes from different angles than normal light and mainly horizontally. Polarized lenses allow only light entering at an angle closer to vertical to pass through. This blocking of horizontal light is what makes seeing with polarized glasses so comfortable
Tests have shown that drivers wearing polarized glasses stop more quickly when suddenly confronted with an obstacle. The same tests also showed that drivers who wore no glasses at all stopped faster than those who wore plain (non-polarized) glasses.
Polarized sunglasses are the best choice for driving in traffic, snow and sea, i.e. in all conditions where we have strong sunlight that enters our eyes after reflection.

Multifocal lenses

Multifocal glasses, organic with anti-reflective and anti-scratch coating, 3rd generation and 4th generation coating that makes the lenses very transparent and clear, with the maximum hardness not easily dirty and very easy to clean. Latest generation design, free form digital construction and the largest visual field of vision. Result: immediate adaptation to multifocal glasses without feeling dizzy...

For the manufacture of multifocal lenses, your physical presence in our store is necessary to take special measurements on your face.

All light-adapting lenses use photochromic molecules. The power of Transitions® technology lies in our exclusive, patented formulas. Each formula is embedded in the surface of the lens. These molecules are constantly and smoothly recalibrated so that the optimal amount of light reaches your eyes whether you're in bright sunlight, under clouds, or indoors.

FROM NORMAL LENSES TO EXTRAORDINARY TECHNOLOGY

Transitions photochromic technology becomes an integral part of the lens through one of two specialized processes.

One process is called immersion. Derived from the Latin imbibere meaning "to drink in", this method uses heat to draw the photochromic dye into the lens itself. After absorption is complete, a scratch-resistant coating is applied to the surface of the lens.

Some lens materials are not easily absorbed. In these cases, another method called Trans-Bonding is used.Where dipping places the photochromic technology below the lens surface, patented Trans-Bonding places the photochromic technology on the lens surface.

Both the imbibing method and the Trans-Bonding method provide the same uniform tint color, regardless of differences in lens thickness caused by lens prescriptions. At Transitions Optical we develop and tailor our processes for optimal photochromic performance, lens durability and compatibility with other lens treatments such as anti-reflective coating.

BEHIND THE WINDSHIELD

Most photochromic lenses react primarily to UV light.

In a car, the glass in a car windshield blocks most of the UV light. That's why most photochromic lenses don't provide adequate darkening in a car. But the special photochromic molecules in Transitions® XTRActive® lenses respond to both UV light and natural (visible, clear or white) light, so they can darken in a car – something no clear lens can do.

We also recommend a pair of prescription sunglasses. Transitions® Drivewear® lenses enhance the driving experience by combining two of the most advanced technologies in the eyewear industry. NuPolar® Polarization eliminates glare from the road and the hood of the car. Transitions photochromic technology adjusts the color and tint of the lenses as light conditions change.

TEMPERATURE AND ITS EFFECT ON PHOTOCHROMIC TECHNOLOGY

The molecules in photochromic technology work by reacting to UV light. However, temperature can have an effect on the reaction time of the molecules. When the lenses become cold, the molecules begin to move slowly. This means it will take a little longer for the lenses to adjust from dark to clear. When the lenses heat up, the molecules speed up and become more reactive. This means they will fade faster. It can also mean that if you're outside on a hot sunny day, but sitting in the shade, your lenses will more quickly detect the reduced UV rays and lighten their color. Whereas, if you are outside on a sunny day in a cold climate and then move into the shade, your lenses will adjust more slowly than in a warm climate.

Transitions scientists are constantly striving to improve our technology and create formulations that strike the perfect balance between UV and lens temperature. In fact, our newest Transitions® Signature® GEN 8TM lenses are more responsive than previous generations – darker outdoors, completely clear indoors, and return to clean faster than ever before.

It's one of the many reasons we're the most recommended photochromic lens brand worldwide.
