Say Stop to the worsening of myopia: MyoStop Lenses, the next generation single vision myopia control lens.

Youth Myopia is one of the most popular topics in today lens global market.

A large variety of myopia control lenses, made up by freeform machines, each of them with a different mathematical and optical approach, has recently become available to the market. However, the techniques upon which current myopia control rely are much older: indeed, everything started years ago with multifocal contact lenses.(1)
At the time, the main goal was to find a way to slow down myopia progression, especially on children and young people. (2)

But what does a myopia disorder entail?

Well, myopia makes you unable to clearly see distant objects, making them appear blurry, whereas close objects still look normal.
Speaking in a slightly more medical approach, with myopia light focuses in front of the retina, instead of exactly on the retina.

With traditional myopia lenses, light correctly focuses on the retina but only in correspondence of the lens center. Therefore, our success was only partial. (3)
Indeed, with traditional myopia lenses, distant objects look clear only in the central vision zone, whereas images in the peripheral zones are still blurry.

Consequently, it can be easily stated that traditional myopia lenses do not entirely solve the problem. Even worse, studies show that a children myopia can even increase the risk of ocular complications later in life (4)

A complete, optimal solution was still needed.

Therefore, we started researching for something that would make all the light always focus on the retina, also on peripheral zones. Contact lenses with defocus turned out to be a good compromise (5) and a starting point for MyoStop future developments, but the actual game changer was the innovative freeform technology. Indeed, freeform technology made us able to create a new generation of single vision myopia control lenses. Currently, Opto+ MyoStop, with its circular defocus approach, is one of the most advanced one.

But how does it work?

MyoStop lens has a fixed-power central zone, whose diameter is calculated each time according to the patient’s specification (the real base value and the power value).

From the central area to the whole lens border, thanks to a mathematical technique called Ray-tracing, MyoStop has a power degression and a slow cylinder increase with radial direction (i.e. pointing to the lens center). The result is a single vision lens with circular defocus.

The circular defocus changes the focus points’positions while moving away from the lens center, in order to follow the eye retina curve as accurately as possible, resulting in a complete resolution of our problem: having a single lens that focues the light on the retina in correspondance of every point of the lens, without blurry images.

As a good side effect, the circular parabolic defocus of the Myostop lens generates a smooth, completely clear lens surface with no porosity, and a less thick if compared to traditional myopia lenses

The Clever Lens

MyoStop is available to all innovative labs using Opto+ LDS.
