Award winning Wavefront and SAM® technologies

What is Spherical Aberration?

When light rays pass through the edge of any optical system, they are focussed differently from those passing through the centre, resulting in blur. This effect is called Spherical Aberration. All optical systems suffer from this effect, including the eye.

 

What is SAM®?

SAM® is a patented technology applied to the contact lens design. SAM® reduces the spherical aberration induced blur significantly, resulting in a visual image that is clearer than that achieved with the naked eye.

 

What is UltraVision's Wavefront Technology?

Wavefront technology enables us to analyse aberrations both of the eye and the eye contact lens system. However, each person's eye has it's own specific aberrations as a result of many factors. UltraVision has incorporated the results of the studies of over one thousand eyes to arrive at a design that offers the best wavefront controlled vision to the widest range of the population.

UltraVision Wavefront designed optics are now available in the new lathe-cut 74% water content Silicone Hydrogel material, Definitive™ by Contamac. This unique combination represents a huge step forward indesign and material technology.

 

What are the benefits of Wavefront optics?

• Improved vision and sharpness

• Improved night vision

• Masking of low levels of astigmatism

• Reduced blurring caused by any rotation of toric lenses

• Increased depth of focus. Early presbyopes can gain up to +1.00DS of near add effect

• Better monovision as the depth of focus effect reduces the difference between the dominant distance eye and the "reading" eye, thus making the system more tolerable

• Reduces near visual stress in young myopes and computer users

• Improves glare effects in those wearers with large pupils

 

What makes UltraVision lenses different to others on the market?

The patented SAM® and Wavefront optics, combined with the full range of powers and parameters are available in many materials, including lathe-cut Definitive™ Silicone Hydrogel material. The Queen's Award for Enterprise - Innovation was awarded to UltraVision for these innovative and state-of-the-art technologies.
