Glasses for sharp vision at multiple distances When you reach the age of 40, you may notice that your eyes are starting to have problems focusing at various distances. If your arms are getting too short for reading a book or computer screen you may need to talk to us. There are 3 solutions to this problem: Progressive Lenses are designed for all-round use, in which the power rises continuously from the distance to the near zone.   Progressive Lenses will provide you with the most comfortable and clearest vision. Your eyes can glide smoothly from the distance to the near range - without encountering any annoying dividing lines on your lenses. The visual zones provide crystal- clear vision at all distances. In the past few years, progressive lenses have been constantly optimized to tailor them even more precisely to the natural process of vision. We recommend using ZEISS Gradal Individual progressive lenses Bifocal Lenses will provide you with clear vision at two ranges: distance and near. Single vision lenses are the solution for anyone who needs glasses for only one distance. Traditional reading glasses, for instance, feature exactly the power your eyes require to focus at a distance of 40cm again.
