Natural 1-tone coloured lensesThe change that whispers.
A single layer of colour, with no limbal ring: the most natural coloured lenses in the range. You change colour without anyone working out how.
What "1 tone" means in a coloured lens
The natural coloured contact lenses par excellence are the 1-tone ones: a single layer of colour, uniform across the whole iris area. No dark ring at the edge, no constructed shading, just a solid tint, calibrated to reproduce a real iris. It is the choice of those who want to change colour without anyone being able to work out how.
In a cosmetic lens, the "tones" are the layers of pigment that make up the iris design. A 1-tone lens has just one: a single tint, evenly distributed across the coloured area of the lens, with the pupil zone left clear and transparent so as not to interfere with vision.
The result is a full, uniform colour, without the limbal ring, the dark border surrounding the iris, that characterises 2- and 3-tones lenses. Fewer graphic elements means less "construction": the eye changes colour, but the design stays essential.
The natural effect: how a single tint works
On light eyes, the 1-tone lens works in harmony with the starting colour: it intensifies it, shifts it or corrects it with a soft result, almost imperceptible up close. These are the coloured lenses that go unnoticed: the "I was born this way" effect.
On dark eyes, the opaque pigments of the Desìo range cover even the deepest irises, but without a limbal ring the effect deliberately stays soft: a believable colour change, not a redrawn gaze. Anyone starting from a very dark iris and looking for full coverage and marked contrast will find the answer built precisely for them in the 3-tones lenses, the reference design for dark eyes.
Who it is the right choice for
The 1-tone lens is designed for those who want the most natural result in the range: those who wear it every day, at the office or in settings where a striking change would be out of place; those approaching coloured lenses for the first time who prefer a gradual step; those who already have an iris colour they love and simply want to make it brighter.
It is not the right choice for those seeking transformation: for a defined gaze there are the 2-tones lenses, for deep realism the 3-tones ones.
Natural coloured lenses with prescription: colour and correction together
Desìo 1-tone lenses are also available with prescription, with powers for myopia and hyperopia: a single lens corrects your sight and changes your colour. For those already wearing contact lenses, switching to colour requires no visual compromise.
For the professional
The Desìo 1-tone line is monthly replacement and is made from Hioxifilcon D, a non-ionic material with 54% water content, with HEMA-Glycerol monomers that retain moisture on the lens surface. It is the line to recommend to two recurring profiles in store: the wearer with a sensitive eye or with previous negative experiences of low-end coloured lenses, and the newcomer who asks for "something natural" without being able to translate the request into parameters.
Three useful arguments during consultation: the single-tint design is the most aesthetically tolerated in prolonged daily wear, because it does not create the "drawn edge" effect visible when the lens rotates or decentres slightly; monthly replacement with an established maintenance routine is the format with the best repurchase loyalty; the availability of powers for both myopia and hyperopia makes it possible to combine correction and aesthetics in a single fitting.

Frequently asked questions
Which are the most natural coloured lenses?
The 1-tone ones: a single layer of colour with no limbal ring, designed on reproductions of real irises. At conversational distance the eye simply appears to be the new colour.
Can people tell I am wearing lenses?
This is the lens designed precisely not to be noticed: no dark border, no constructed shading. The colour blends with the natural light of the eye.
Do they cover my dark eyes?
Yes, the pigments are opaque and covering, but the effect stays soft. If you are looking for full coverage with strong contrast on a very dark iris, 3-tones lenses are the right choice.
Are prescription versions available?
Yes: the 1-tone line is available both plano and with powers for myopia and hyperopia.
