Good vision requires more than just the correct prescription!
Lens alignment to match your face in the frame is crucial to get the best results!
That's why at Waipapa Eyecare we have invest in the latest digital centration technology from Zeiss. The VISUFIT 1000
Modern Digital Technology for Modern Digital Lenses
Poor lens alignment is arguably the number 1 reason for poor lens performance resulting in less than optimal vision.
Studies show when progressive lenses are poorly aligned as little as 1.0mm then up to 50% of the intermediate and near vision areas are compromised. Stronger prescriptions suffering more than weaker prescriptions.
So does using a felt tip pen to mark your pupil centre in the frame and then measuring that with a ruler cut it any more? Of course not, especially in this digital age with modern digitally surfaced progressive lenses that can now be customised to your face and frame shape if you provide all the needed and correct measurements you can get a fully compensated progressive lens to match your unique face and frame shape combination, what we refer to as "as worn".
The question you most likely have is what does this "as worn" mean?
The short answer, the best possible lens prescription in the frame you have chosen and matching your unique face.
The long answer, is that when you are in the Optometrist's chair they work out your prescription you might be surprised they are using a lot more factors than you might think. For instance the distance the lenses are from your eyes, the amount of tilt or angle the lenses are on and the amount of wrap around your face the lenses have.
As you can know doubt imagine sitting in the Optometrists chair is a controlled environment the phoropter (the device in front of your eyes, with all the lenses in it) is sitting nice and level with no wrap or tilt, depending on your face the distance from it to your eyes can vary. Then in the real world you go and chose a frame you like the style of it really is unlike to exactly the same.
So when the computer program that generates your new lenses is provided with all the needed and correctly measured data like, tilt and wrap etc you get a compensated lens to ensure you are getting the script the optometrist provided "as worn" in the frame your have chosen and to your unique face. This means small changes to the lenses prescription will be made so the that actual power you need is provided.

Quick, easy and accurate centration data means better resultsThe ZEISS VISUFIT 1000 creates a 180-degree view of the consumer's face and the frames using nine cameras and 45 million points. The centration data determination is based on 3D coordinates.
