Preslux
The Preslux multifocal lens gives centre distance and a progressive add that provides both near, distance and intermediate vision, ideal for computer work and reading. Viewing zones can be adjusted according to pupil size to facilitate sharper vision. It can also be manufactured in reverse, so the addition is in the centre if preferred. The aspheric design is said to provide extra comfort for the patient and Preslux is available in a wide range of gas permeable materials. The Preslux lens is offered on a 28-day trial package for new patients with an exchange facility incorporated.

VTI
NaturalVue 1-Day Multifocal
NaturalVue 1-Day Multifocal from VTI is available from Positive Impact. CE approved for both presbyopia and myopia control, the lens uses patented centre-distance optics and, inspired by advanced camera optics, the design allows for an extended depth of focus (EDOF). The NaturalVue design utilises a smooth, rapidly increasing, highly aspheric power curve that causes blur in the peripheral retina creating a virtual aperture. This creates an EDOF where distance, intermediate, and near vision are all in focus at once. NaturalVue can be more simply considered as a single-vision lens and is fitted as such, resulting in high first-fit success.
Power range: +4.00D to -12.25D (0.25D steps)
Add power: One universal EDOF design effective up to +3.00D
