4 Ways to Deliver Bespoke Lenses

10 May 2021

Being able to offer a personalised service to your patients is something every independent optician should strive for.

Being able to offer a personalised service to your patients is something every independent optician should strive for. It can help to set you apart from your competitors and means you can keep up with the bigger chain practices on the high street. Bespoke lenses can be incredibly important to a patient, but it’s your job to show them why.
 
Bespoke lenses are tailored to each patients’ vision needs and lifestyle, delivering the sharpest and most comfortable vision possible. It can make all the difference for patients who wear glasses frequently, with a number of new measurements and more precise examinations. At Essilor we can help you deliver personalised lenses through 4 different methods.
 

Precise refraction

 
Traditional methods of refraction typically measure to the nearest 0.25 D, but research by our team has proven that the majority of people have much more sensitive vision than this. After years of research and analysis, we have developed a much more precise way to measure your patients’ vision, known as AVA.
 
Advanced Vision Accuracy allows you to deliver a more precise eye examination, measuring refraction at 0.01 D increments. Together with our breakthrough phoropter, Vision-R 800, you have the opportunity to take advantage of cutting-edge technology and a more accurate prescription.
 
An AVA prescription can be integrated into Essilor lenses, including Varilux and Eyezen.
 

Measuring patients’ Eyecode

 
Every patient has an Eye Rotation Centre, indicating how the eye rotates around a fixed point. Most lenses are manufactured based on the assumption that everyone’s Eye Rotation Centre is the same, but our research shows it can differ by up to 30%.
 
Understanding your patients’ eye anatomy can help you to deliver a tailored diagnosis, with highly accurate measurements that result in optimum vision. These measurements, known as Eyecode, can take into account a number of parameters to achieve better lens performance.
 
Using the Visioffice X or Visioffice 3, enhance the in-practice experience and demonstrate your expertise.
 

Considering posture and visual behaviour

 
For patients who require a reading prescription, the near vision zone of the lens is crucial. How a patient sits when reading something through their lenses can impact the effectiveness of their glasses, which is why you should consider measuring posture and visual behaviour to ensure an optimised reading zone.
 
Near Vision Behaviour is an important measurement to deliver personalised lenses for those who need varifocals. Using a parameter clip on the frames and a reading test on a tablet, you can measure eye and head movements so that the lens and the frame are designed for the wearer specifically. This can make it easier to adapt to varifocals, as well as a near vision zone that is clear and sharp.
 

Integrated frame measurements

 
It’s important not to forget the frames when fitting personalised lenses. Measuring how the frame sits on your patients’ faces can help to achieve optimal vision, ensuring the lens is made specifically for the way they wear their glasses.
 
Frame fitting parameters can reduce lens power error and improve vision zones. As so many frames are different styles, and everyone’s anatomy differing, you can further tailor lenses with these precise measurements. Measure the pantoscopic angle, dihedral angle and back vertex distance to dispense lenses that meet your patients’ needs perfectly.
