Lensus is a brand of contact lens that is made by Chromeyes lens. Lensus is a photochromic contact lens is an improved version of the initial development made by IBN. Shortly after the initial developments, Chromeyes adopted the technology and rights to produce and modify the photochromic contact lens.

 

Its researchers did further experiments and development to improve and create a photochromic contact lens that could be mass produced. This project cost the company SGD6.7 million.

 

It was only until a few years later in 2013, that the company successfully created an improved version of the photochromic contact lens. This allowed the production of the first commercial piece of the contact lens which carries the brand name, Lensus. It is said to be the world’s first photochromic contact lens.

 

Chromeyes has revealed that the Lensus will be a monthly wear contact lens and is priced slightly more expensive than a regular contact lens due to its technology and feature.

 

 

WHY LENSUS

 

 

 

 

 

 

 

 

 

 

Photochromic or Photochromatic lens are lens that darken when exposed to ultraviolet (UV) radiation. The first form of such lens were developed as early as the 1960s but was only made popular by Transitions in the 1990s.

 

The photochromic lens consists of millions of molecules that is made up of substances such as silver chloride that is embedded within the contact lens. When these molecules are exposed to UV rays from the sunlight, a chemical reaction will occur to cause the molecules to change shape. Thereafter the new molecule structure absorbs portions of the visible light. This causes the lens to darken. The intensity of the UV rays affect the number of molecules that changes shape.

 

Once the lens goes indoors or perhaps somewhere that does not have any UV light, another form of chemical reaction occurs. In the absence of the UV radiation, the molecules will revert to their original shape. This causes it to lose their light absorbing properties, and eventually losing its darkness.

 

While the process seems to be complex, it actually happens rather rapidly. Thus making the photochromic lens effective and popular.

One might then wonder would these photochromic lenses darken when indoors in the presence of artificial light. Without UV light, the molecules are transparent to the visible light. Thus a chemical reaction will not occur and the lens will not darken.
