Once you have found an optometrist, it is quite normal for you to want to browse the store in search of nice-looking spectacles frames. However, not all spectacle lenses are suitable for every type of spectacles frame, so it is usually better to choose your spectacle lenses first of all. If you are looking for relaxed and better vision, it goes without saying that the spectacle lenses represent the most important component of your new spectacles. You will only be able to rely fully on visual support from your spectacles if you select the correct spectacle lens.
In the past, mineral glass was used predominantly in the manufacture of spectacle lenses, whereas today, plastic lenses are becoming more and more widespread. This development brings with it some key advantages: the increased breaking resistance of these lenses ensures a lower risk of injury. High-quality special plastics and a good coating offer protection against painful pressure marks and scratches. But there are other aspects which play an important role when choosing the perfect spectacle lenses: apart from the now commonplace aspect of dioptre strength, other important factors include the refractive index of the material (which is important for the lens thickness), the so-called aspherical geometries (which reduce distortion at the edges of the lens), antireflective and curing qualities and breaking resistance. Additional lens coatings or finishes can help to make life with your spectacles even simpler. Why not try a hydrophobic or antistatic coating, for example?
Our tip: If nothing else, the spectacle lenses should have a good and efficient anti-reflective coating. This is because reflections caused by spectacles are very distracting when out in the sunshine, driving at night or working at the computer. Furthermore, antireflective spectacle lenses make the wearer almost oblivious to the fact that he or she is wearing spectacles.
Perhaps you are thinking about buying tinted or self-tinting spectacle lenses. But be careful: there is a huge difference in quality as far as self-tinting spectacle lenses are concerned. The decisive factor to consider when making a purchase is that the so-called photochromic spectacle lenses should react as quickly as possible to changing light conditions, fading back to the clear state indoors and darkening to a tone similar to that of sunglasses in the sun or other bright light. Also of vital importance is that the lenses provide 100% protection against UVA and UVB radiation.
