The optical insert sits between the sunglass lens and your face, limiting airflow; for this reason, fogging may occur if the prescription lenses installed do not feature an anti-fog treatment. To reduce the problem, we recommend asking your optician to apply an anti-fog coating to the insert’s lenses during installation.Alternatively, you can use anti-fog wipes, which are widely available on the market and can be applied when needed.

The optical insert is positioned inside the eyewear, behind the sun lens, and is smaller than the main lens. As a result, the peripheral area of the sun lens does not include optical correction, which may create the perception of a slightly reduced lateral field of view compared to direct prescription sport lenses. This is a common characteristic of all optical inserts: the corrective lens is placed directly in front of your line of sight to ensure sharp vision within the primary visual axis, while the lateral area remains outside the corrected zone. This effect does not compromise performance, but it is important to be aware of it when choosing between an optical insert and corrective lenses mounted on adapters that cover the entire field of view. Scicon Sports offers corrective solutions both with optical inserts and with full-coverage prescription lens adapters.
