Overnight contact lens
The Ortho-k lens for spherical and toric applications up to -6.50
The Double Reservoir Lens (DRL) is a welcome addition to the existing Ortho-K overnight lens by the double reservoir principle. This system has a simplified adjustment technique, making the result logical and predictable for measuring the contact lens. The DRL lens is a patented design which the centering improves and ensures that there is more fluorescein pattern control on the end result.
