In an attempt at ensuring your comfort and convenience of vision, we offer a wide range of lenses made from various materials:
Mineral (glass) – traditional
Organic (plastic) – lighter than mineral and safer -if broken they do not produce sharp chips.
Polycarbonate – very strong and resistant, even to a strong impact, lenses recommended for individuals living an active lifestyle.
TRIVEX (polyurethane) – manufactured based on advanced technology enabling the achievement of the most desirable features such as resistance to impact, highly advanced optical properties (characteristics) and lightweight. Their surface is hardened with a varnish effectively protecting the lens against scratches and increasing its transparency.
Regardless of the material used in the lens manufacturing process, we also offer a possibility of making a choice consistent with one’s own needs and expectations. This choice may also concern the colour or manner of colouring:
- photochromic – having the ability to darken and lighten up depending on the changing light conditions
- coloured – chemically coloured
Division of lenses depending on the field of vision:
- monofocal – basic lenses used for correcting short-sightedness or far-sightedness are characterised with a single-range visual field – distance (only for far-sighted or short-sighted).
- bifocal – intended for individuals who need two pairs of glasses – for close (e.g. for reading) and distant viewing - and do not want to change glasses each time. They are characterized with a visible line of division between the close and distant field range (the-so called built-ins) which results in a characteristic jump when changing the range.
- multifocal (progressive) – in contrast to bifocal lenses they do not have any visible line between the close and distant range and they are characterised with a natural vision at all distances. The passing between the far and close range is smooth (indirect range field), which increases the visual comfort and makes it more natural; lack of the divide improves the aesthetic quality.
Additionally, in order to increase the comfort and aesthetics, it is possible to enhance the individual parts of the lenses with suitable coating:
- anti-glare screen – this coating increases lens transparency by eliminating unnecessary glare and shine. It also improves contrast, visual comfort and considerably improves aesthetics of the spectacles. It also reduces eye tiredness during the work with the computer, TV watching or staying in spaces with artificial illumination. It also contributes to increased driving safety, at night or in the rain.
- hardening coating – this coating ensures increased resistance to scratches thus extending the life of the glasses.
- water-repelling coating – this coating prevents accumulation of water and steam thus reducing lens fogging.
- antistatic – this coating eliminates gathering of dust and dirt on the lens. It is an effective barrier against dirt.
- oleophobic coating – this coating makes it easier to keep the lens clean.
Lens thickness, weight and aesthetics are influenced by the so-called refractive index, which is characteristic of the indexed lenses. The higher the index, the thinner and lighter the lens, which converts into the wearing comfort as well as appearance. Due to increased refractive index, the lenses may be thinner than the standard ones up to even 60%. The aspherical structure also has influence on lens appearance and visual quality. This construction allows to eliminate all types of aberrations and other optical deviations thus enabling perfect vision in the middle as well as peripheral regions of the lens.
