Tha glass lenses
Glass is definitely the best mean through which we can see the world; thus the best mean to create a lens that can grant the Well-seeing.
The distortion of light passing through a transparent medium is lower in glass than in any other material. As light passes through a transparent medium, it is fractioned into a spectrum of colours, this effect is known as colour dispersion. Glass is capable of minimising this effect better than any other material, granting thus a perfect vision.
Glass is one of the hardest existing materials and its hardness is due to the temperature to which the oxides are melted. This inherent feature allows adding to the melting the Rare Earth Elements which are compulsory to make the lens work as a colour equaliser, thus selecting particular wave-lengths and enhancing in this way both contrast and colour rendering. Glass is a steady material as well, so that it is possible to cover it with coatings and mirror effects which can both protect and grant a visual efficacy over time.
Glass hardness prevents any deformation due to temperature excursion or mechanical stress, which can be caused, for example, by the environment as well as the frame. Furthermore, we should not underestimate the advantages of glass hardness such as making the surfaces of the lenses hardly scratchable. As a matter of fact, scratches and distortions (both evident and barely visible) may be irrelevant to wearers, but in the long term they may stress their eyes.
Its inherent characteristics enable the optical glass lenses to keep their features unaltered over time, preserving both the comfort and the wellness of those who wear them.
Finally, glass is a totally natural material, inert and easily recyclable, as a consequence, a glass lens is not only useful to take care of people’s eyes, but also the best product to take care of the environment.
