Statistically speaking, four and a half million German spectacle wearers are active in sports. It is clear that brand manufacturers such as Oakley see this target group as the biggest growth area for their sports eyewear product line. Annual sales increases of around 20 per cent speak for themselves. On the other hand, optically corrected sports glasses are not the only way to see clearly during sport despite impaired vision. The alternatives are contact lenses or laser eye correction surgery.
If you prefer optical sports glasses, you have to choose one of three systems. Glasses with correction adapters are the simplest designs: An optionally available correction insert is clicked into a standard pair of glasses. These glasses are relatively inexpensive and can be used in a variety of ways. The uncut front lens can be easily replaced - good if interchangeable lenses with different tints or brightness gradations are to be used.
If you wear contact lenses from time to time, simply remove the optical insert. However, clip-on glasses usually fit worse and more tightly than the same models without corrective inserts, as the basic models are not specially designed for their use. The soiling and fogging surfaces are doubled and the clips sit very close to the eye. As a result, the lenses can come into unpleasant contact with the eyelashes. The mostly small optical inserts also restrict the field of vision.
