The Orion freeform progressive lens series uses Digital Ray Path technology to determine unique lens calculations for each wearer, taking into consideration viewing angles through the entire lens, and ensuring reduced distortion and improved lens performance for any gaze direction.
Some patients find progressive addition spectacle lenses (PAL's), which are used for the correction of presbyopia, a difficult type of lens to wear, possibly because of the peripheral distortion.
What are progressive lenses? Answer: These are multifocal lenses that correct vision at different working distances, from reading distance to far distance. Unlike bifocals, they have a gradual change in prescription and don't have visible lines that separate the segments, so they look just the same as single vision lenses. The distance vision part of the lens is usually in front of the pupil.
Glasses with progressive lenses are the best option for patients with presbyopia or eyestrain in short distances. How do progressive glasses work? When the user looks far away, the pupil goes to the upper part of the progressive lens, looking into the far vision zone. If we look in the medium zone of the lens, we will be in the medium vision.

Seiko's patented design is the first to use a perfect sphere on the front surface of the lens. Conventional progressive lens designs place or split the power between the front and back surfaces. This elegantly simple, but complex step eliminates the magnification factors that cause virtually all of the swim and sway distortion found in conventional progressive addition lenses. Wearers.
Rotlex Mapper is a high-resolution lens inspection system for spectacle lenses. Within 3 seconds, the Mapper provides high resolution power and cylinder maps, of all types of lenses: Spheric, aspheric, toric, atoric, front, back and double progressive, bifocal, trifocal, polarized, unpolished, and more. Other than the prescription values (Sph, Cyl, Ax, Add), the maps provide a huge wealth of.
Free form digital progressive lenses are called Free form because they can be fully customized. Manufactures of the lenses are not limited by a fixed or a static design, but can fully customize your vision correction for optimal results. In the same way a tailor fit you with a new outfit, different personal measurements are taken into the account. Measurements such the distance between the eye.
