Menicon Niji

A semi-customised family of lenses with the simplicity of fitting a disposable.

Why a semi-customisable soft lens design?

One size does not fit all when it comes to soft contact lenses. That is why we designed Menicon Niji with extended parameters, which give semi-customised designs for each of our patients.

Only 50% of patients fall within the average horizontal visible iris diameter (HVID)¹

Clinical studies have shown us that the average HVID is between 11.6 to 12.0 mm. This value is used to calculate the diameter of most soft lenses.

However, as seen in the bell curve [fig. right], this diameter range fails to cover the entire HVID spectrum of the population. For patients at the extremes on the right and left of the bell curve, these soft lens diameters are not satisfactory and these patients go unaddressed.

The average horizontal visible iris diameter (HVID) is 11.6 to 12.0mm¹, from which we usually calculate the lens diameter but only 50% of patients fall within this range of HVID¹. This means that the other half of the patient population may be wearing contact lenses that are suboptimal as they are either too large or too small for the patient’s eye².

Standard base curve & diameter range of parameters do not fit all corneas optimally.

Conventional disposable soft lenses in the market have only one or two standard base curves and one or two standard diameters for the entire lens wearing population. However, it is known that this range of parameters does not fit all corneas optimally, leaving some patients without access to an ideal fitting.

Measuring sagittal height provides more insight into the corneal profile.

A solution to this limitation is to stop analyzing the base curve and diameter separately and look at them together as a set. Together, the base curve and diameter determine the sagittal height of the cornea and the lens. This is a much more valuable parameter than just looking at base curve and diameter alone as it helps to provide more context into what the corneal profile actually looks like.

In addition to sagittal height, optimizing how the lens fits the periphery of the cornea plays a critical role in ensuring uniform pressure across the lens which ultimately contributes to comfortable lens wear.

Menicon Niji considers all of these fitting factors and provides a lens that more accurately matches the cornea to give patients a more optimal lens fit.

Meet Menicon Niji: Personalised Comfort and Clarity

Niji, which means rainbow in Japanese, embodies our latest semi-customisable soft lens design—Menicon Niji. Available in a spectrum of parameters and crafted uniquely for each person, Menicon Niji offer a personalised soft contact lens experience.

Much like a rainbow appearing after rain, Menicon Niji lenses bring clarity and comfort, particularly for those who've encountered challenges with standard lenses.

In the world of eye care, comfort and clear vision are key. Explore how Menicon Niji puts your patients first and ensures they keep coming back.

Wide Range of Parameters	Easy to Fit	Healthy and Comfortable

Extended range of parameters (BC, diameter, power, cylinder, axis, multifocal designs). Available in six different radius-diameter combinations.	So simple, Menicon Niji monthly lenses can be fitted without a topographer.	Lenses are made from silicone hydrogel material, allowing optimal oxygen transmission for healthy, comfortable wear.

Menicon Niji Indications
