THE HOME OF
New multifocal concept
NATURAL ACCOMMODATION LENS
NAL
®
Following extensive scientific research and empirical studies of eye-lens ergonomics, current frame shapes, fitting statistical data, and patient visual habits NAL® Concept was born. It is not a no-line trifocal like progressive lenses. NAL® is a true multifocal lens that provides correction from infinity to near reading in one continuous individually adjusted power curve. Natural Accommodation Lens is a life changing experience for multifocal wearers worldwide.
​
NAL® provides unique opportunity for independent labs and ECPs to offer their patient most advanced and comfortable multifocal solution. Client and patient retention, competitive advantage and economic rewards are just some of additional professional benefits.
​
QLDS’ NAL® is a commercially viable digital multifocal lens available for implementation to all freeform technology capable optical labs globally.
Multifocal Lens Concepts
COMPARITION
NAL CONCEPT
No adaptation period
No peripheral swim effect
Provides clear natural instinctive vision in all distances
No fitting height required
Visual fields are funnel shaped rather than hourglass shaped.
Smoothly connected visual fields provide natural vision from infinity to 14 inches.
Wide Intermediate visual field provides effortless mid-range navigation.
Because NAL mimics natural accommodation from 20ft to 14 inches it eliminates eye fatigue due to new habits of excessive indoor living
PAL CONCEPT
Requires adaptation period
Patient will experience nausea or dizziness due to peripheral waves and distortions
Navigation through distance, intermediate, and near vision is cumbersome. Patient would have to move his/hers head to see objects at different distances
Fitting height required
Costly redos and non-adapt issues due to fitting height errors
Eye fatigue due to PAL Concept constant utilization of auxiliary mussels
Low patient retention due to common unfulfilling experience
Lack of competitive advantage
