Now, two of the world's leading manufacturer of contact lenses introduced lenses with the continuous wearing period - up to thirty days, namely:
- Pure Vision lens company Bausch & Lomb;
- Lens Focus Niqht & Day of Ciba Vision.
These lenses have unique material properties. But even in these lenses, it is necessary to increase the duration of wearing progressively according to the schedule.
