Progressive lenses
Progressive lenses
Progressive lenses are a type of optical lenses used to correct distance, intermediate (computer usage), and near (reading usage) at the same time.
Progressive lenses are an update on bifocal and trifocal lenses. Both of these more traditional types of lenses have telltale lines in the lenses. With progressive lenses the transitions are invisible. You choose progressive lenses if you are nearsighted and also need reading glasses.
Progressive lenses ensure that you can see well at any distance, without having to change glasses.
What is Presbyopia?
Presbyopia is an eye condition that can affect everyone between the ages of 40 and 45. Then objects up close start to look blurry. In order to see clearly while reading, you would have to put your arms much further away from your eyes.
How do progressive lenses work?
With progressive lenses, there’s no need to buy multiple pairs of eyeglasses. The lenses compensate for long-distances, short-distances, and everything in between. Possibly the most worthwhile benefit is, the way in which progressive lenses look like any regular pair of eyeglasses since there are no visible bifocal lines. Older versions of bifocal and trifocal lenses had not yet fully integrated a transition between the different lens powers. With no abrupt transition from one distance to another they resemble a more natural vision.

Progressive lenses from Focus
Our progressive lens designs offer great comfort, allowing you to adapt more quickly to your spectacles.
Digital design
FlexiView
Bringing flexibility to the occupational lens range, FlexiView gives the power to define the distance vision offering a choice of maximum viewing distance ranging from 0.5m – 6m. With a default working distance of 6m, Focus Computer compliments the office range by offering a remote worker lens, the key advantages of an office design while not hindering indoor vision to help manage other household duties
SmoothOptics
Lenses incorporating SmoothOptics are created using this PATENTED approach which reverses the normal design process. Rather than create a surface and analyze to determine its optical performance, the starting point is describing the Mean Power required by the eye at all points of the lens and then deriving the surface to match this ideal.
- A smoother, more even, Mean Power profile
- Reduced swim in the peripheral zones
- Greater comfort and faster adaptation
EyeView
Ophthalmic lenses have power errors when viewing away from the optical center of the lens. EyeView technology uses specially developed software which modifies the entire lens to correct power errors. Each lens is customized to the prescription.
- Provides more consistent optical performance
- Clearer image quality
EyePower
EyePower is an extension of the EyeView principles, where the unique and comprehensive raytracing analysis considers the patient’s parameters and individual’s choice of frame (back vertex distance, pantoscopic tilt and face wrap) to compensate the prescription.
- Ideal for sports and fashion wrap frames
- Sharper and higher resolution vision
CustomForm
This is a cohesive approach to lens design, which considers a progressive lens as a single entity rather than an accumulation of individual points. It utilizes geometric building blocks (continuous splines and ellipses instead of separate points) at the time of creation to define the whole lens surface rather than simply minimizing distortion in primary parts of the lens. The intrinsically natural design results in:
- Better overall performance
- Higher adaptation rates due to increased patient comfort
