Crossbows ComputerEyes

Features of design

• A superior design of office progressive lens
• Low distortion, soft design
• 4 Dynamic powers available
• Moulds in 1.498 and 1.56 indices

The ComputerEyes design is a lens designed primarily for use in an office-type environment. It is not a traditional progressive design, but rather is an alternative to a reading lens, providing clear vision for reading and intermediate viewing. The wide range of dynamic powers allows the ideal choice to be made for all reading additions up to 3.00D and also allows the user to benefit from fully corrected reading and intermediate vision and maximised distance vision. The design reduces eye and neck strain associated with long term use of computers.

ComputerEyes Moulds 1.498 and 1.56 Index

Note:

1. Ø81 mould is designed to produce Ø75/81mm Progressive lenses when used with gaskets.
2. Other diameters and specific edge configurations are possible, subject to additional charges.
3. Moulds with a centred design are also available for the manufacture of finished progressive lenses, subject to additional charges.

ComputerEyes Design Base Curve and Dynamic Power Range for Ø81mm moulds:

Note:

1. Dynamic power is the total drop in power from reading to distance area.
2. Lens is machined to the reading prescription (Distance prescription + addition power).
3. Lens is verified in reading reference circle only.
4. Dynamic power is selected from addition.
