Dr Michael Lange hosts "ask the dr" today with his guest Michael Walach. Michael is an optical lens industry veteran and expert. The evolution of presbyopia spectacle lens correction is here today with the all new Eyefocal Omni NAL. NAL stands for natural accommodation lens and was invented by Michael Walach. NAL is a true multifocal lens that provides correction from infinity to near in one continuous individually adjusted power curve. Eyefocal Omni NAL is the next generation in lens concept for the over 40 crowd with presbyopia. The Lange Eye Institute in The Villages Florida is one of the first in the country to offer this new Eyefocal Omni NAL concept. Progressive lenses have been around for over 60 years and have not changed a significant amount in this time period. The NAL is a revolutionary new lens concept that allows people to see clearly in the distance and up close with no peripheral distortion or "swim" sensations. This new lens concept also reduces human error in the Measurment's for the progressive lenses since no seg height measurement is necessary with this lens. Dr Lange feels this new NAL will be a much better option for patients with macular degeneration or patients with visual field loss from a stroke or traumatic brain injury. Both Michael Walach and Dr Lange feel this NAL will be a big advantage for anyone playing sports over a progressive lens. Today's show was upbeat, educational and had lots of good live calls, Dr Susan Summerton called in from a conference and updated everyone on the latest in eye care technology. Dr Lange also briefly mentioned the all new Fortifeye Next Gen Macular Defense supplement is now available.
