The efficacy of myopia control maybe influenced by the competing lights that form peripheral myopic images and peripheral hyperopic images through the myopia control lenses. Since the distribution of the treatment lenslet or segments differ from brand to brand, the frame selection should take into account of such differences.

The Stellest lens is the latest lens designed for myopia control which makes use of the broad concept of peripheral defocus. Several researches have shown that lenses with myopic peripheral defocus are able to reduce the rate of myopia progression. With Stellest lenses, instead of a single myopic defocus plane, they constructed a volume of myopic defocus (VoMD) where the defocusing plane is stretched over a segment.

An ideal frame shape for Miyosmart lens would maximize the treatment zone and minimize the excess lens surface beyond it. Some amount of treatment zone truncation and excess lens area can be expected as the frame size ultimately needs to fit the user.

Research in myopia control using optics and advances in lens cutting technology has led to the introduction of Hoya Miyosmart myopia control lenses. Due to the research and technology used in the development and production of Miyosmart, it is currently the most expensive eyeglasses lens for controlling myopia progression. Clinical studies have shown that Miyosmart is able to reduce the eye axial elongation by more than 60% compared to children using single vision lenses [Lam et al 2019]. Given the price of the lens, it is wise to select frame designs that can maximize treatment outcome.

Using eyeglasses to control myopia progression is the safest and least invasive method. With research in myopia progression, major lens companies like Hoya, Essilor and Zeiss have introduced their version of myopia control lenses with clinical results to substantiate their claim. In practice, the results from eyeglasses fitted with myopia control lenses varies greatly.

Slipping glasses is one of the most annoying and common issue faced by its users. From an engineering perspective, most glasses frame design is mechanically unstable. Here is the top ten solutions to stop glasses from slipping.

When your glasses is hurting your ears, it is due to excessive pressure on them. The pain may be at the top of your ears or at the back. As the ear is made of soft cartilage, it is sensitive to pressure. It is difficult to get the adjustment right on the first attempt as the optician needs to make sure that the glasses also do not slip.

Most eyeglasses frames in the market are susceptible to slipping as they are not engineered to tolerate movements or lowering of your head. This may reduces the effectiveness of treatment using multifocal eyeglasses such as Myopilux as the user is not looking through the correct area on the lens if it slips

Most conventional frame uses friction as the primary support to hold the glasses on the face. Friction comes from the contact points at the temple and nosepad. As the face tilts down, the weight of the lens gets shifted away from the nosepad and the friction reduces. Much of the holding force now depends on the temple. There are three areas of force application for the temple to hold the glasses. The first is support from friction between the temple and the side of the head. The other two are mechanical support by the ears and by the head. Most temple tip designs will have at least one primary support.

Adjustment of the eyewear frame on the user is often based on the fitting triangle. These three contact points, namely, the nose bridge and the crest of both ears support the eyewear on the face.

Facing forward, the main force that keeps the eyewear in place is friction from the nosepad on the nose. When the friction from the nosepad is adequate, friction from the temple is not required...

Friction is the primary force that keeps your eyewear from slipping down under gravitational pull. Therefore, your eyewear will start to slide down when friction is unable to keep it in place.

In engineering, friction is the force from the applied force and the friction coefficient (µ) between the two materials in contact...
