The success story is based on first-class quality at an attractive price. At the same time, Filtral is distinguished by a keen sense of trends and new product ideas. The most important target groups are large retailers such as hypermarkets, drugstores and discounters.
Both retailers and consumers can be sure that they will be reliably supplied and receive first-class products. These are equipped with a multitude of features - such as break-proof panes, feather-light frames and a trendy design - and are available at an attractive price. By the way, this also applies to online mail order.
Two different lens materials are essentially used in the manufacture of our Filtral glasses. Made with OC-LIGHT LENS technology, the plastic lenses are also noticeably lighter and thinner.
Adjustable, comfortable, resistant – glasses frames must fulfil many requirements. Here, the choice of a suitable material plays an essential role. In addition, the frame should also satisfy any aesthetic requirements.
With the manufacturing of Filtral sunglasses and reading glasses, we distinguish between two groups of frame materials.
Alongside an attractive design, the highest levels of quality and safety are also our top priorities. The quality of the products is also regularly checked by recognised testing institutes.
Lenses of sunglasses and reading glasses must not have any material or surface defects that could impair vision. The optical correctness of the lenses is achieved when the view seen through them is free from distortion and accurate.
In order to test the durability and resilience of sunglasses or reading glasses, the mechanical properties of the glasses are tested alongside the optical properties.
All Filtral metal glasses are covered with an additional coating during production to prevent any nickel from being released. Filtral glasses are below the specified limit values and are therefore not harmful to the wearers health
