What are MiYOSMART lenses?

Short-sightedness (myopia) is a widespread visual defect. According to a WHO estimate, 50% of the world's population is expected to be affected by short-sightedness by 2050.1 Theonset of myopia is becoming increasingly common in childhood.

The innovative MiYOSMART spectacle lens for myopia management in children and adolescents can slow downthe progression of myopia by an average of 60%2 or stop it completely.

What is short-sightedness (myopia)?

Myopia is a congenital or acquired visual defect. Among other things, it occurs when the eye grows too quickly and becomes too long. In this case, the rays of light are focussed in front of the retina instead of on it. Short-sighted people see distant objects indistinctly and blurred, while they recognise close objects without any problems. An eye test reveals negative dioptre values, e.g. -1.00 dpt, and the glasses are normally fitted with so-called ‘minus lenses’.

Short-sightedness is often noticeable in children at school when they are unable to recognise what is written on the blackboard. If myopia in children and adolescents is not corrected, this can lead to permanent visual impairment.

Why is myopia increasing in children?

Studies suggest that myopia will continue to increase due to increasingdigitalization andchanges in children's lifestyles.3,4Children are using more digital devices, reading and learning on computers, and thus performing more activities in the near vision range. At the same time, they are spendingless time outdoors. Studies show that spending more time outdoors can reduce the risk of myopia.1 Whatexactly causes this effect is not yet fully understood scientifically.Genetic predisposition(e.g. myopia in parents) also plays a role in myopia.1

MiYOSMART lenses counteract myopia

MiYOSMART is the first non-invasive solution developed specifically as a lens for myopia management in children and adolescents between the ages of 6 and 18. A two-year clinical study shows that the special lenses can slow down the progression of myopia by an average of 60 %2, thereby protecting the quality of vision and well-being of your children in the long term.

How MiYOSMART works

The MiYOSMART lens corrects short-sightedness in the central zone like a normal single vision lens. This means that if your child's eye test has shown a short-sightedness of -1.00 dioptres, the MiYOSMART lens has -1.00 dioptres in the central zone.

The surrounding D.I.M.S. zone contains around 400 tiny segments of +3.5 dioptres each. D.I.M.S. stands for ‘Defocus Incorporated Multiple Segments’. The segments with a positive dioptre number cause a different visual acuity correction in the periphery, i.e. the outer area of the field of vision. This means that the growth of the eye length is not excessively stimulated and thus slows down the progression of myopia.

The special properties of the lenses are only visible against the light or on closer inspection. Otherwise, the lenses are visually indistinguishable from normal single vision lenses.

FAQ about MiYOSMART

1. has the efficacy of MiYOSMART been clinically proven?

Yes, a two-year clinical trial (RCT) conducted between 2014 and 2017 with 160 children aged 8 to 13 years shows that MiYOSMART technology slows myopia progression in diopters by an average of 59% compared to conventional single vision lenses. Axial length growth is slowed by 60% compared to conventional single vision lenses.*

2. what age is MiYOSMART recommended for?

Typically, myopia progresses most rapidly in children between the ages of 8 and 13. Myopia management with MiYOSMART lenses can be started at any age if progressive myopia is present. If the spectacle wearer receives the first spectacle lenses at a low myopia value, the benefit is greater in terms of avoiding the risk of developing high myopia.

3. will there be difficulties with familiarisation?

Probably not; however, some children need a familiarisation period of up to 2 weeks for peripheral vision, i.e. vision in the peripheral area. We recommend that children cautiously begin sporting activities with the new spectacles for approximately 1 to 2 weeks during the familiarisation period that may be required. To maximise the benefits of myopia management, the glasses should be worn throughout the day.

4. are additional check-ups or follow-up examinations necessary?

Yes, in order to maximise the benefits of MiYOSMART, it is recommended to have the status of myopia progression and eye health checked at regular intervals (every 6 months). In addition, the manufacturer Hoya recommends checking the anatomical fit every 3 months to ensure that the spectacle frame is the correct size and therefore provides an accurate image of MiYOSMART.

5. are all spectacle frames suitable for MiYOSMART?

Yes, all frames are generally suitable. Plastic or metal frames are ideal, but rimless frames can also be used. A minimum disc height of 20 mm should be taken into account.

6. is the aesthetics of the lens affected by D.I.M.S. technology?

Thanks to Hoya's advanced manufacturing technology, the lenses have a flat surface. The tiny segments are only visible against the light and on closer inspection. The surface therefore resembles a normal single vision lens.

7. is the MiYOSMART lens material safe?

Thanks to Hoya's advanced manufacturing technology, the lenses have a flat surface. The tiny segments are only visible against the light and on closer inspection. The surface therefore resembles a normal single vision lens.

8. can MiYOSMART lenses be used in conjunction with other myopia management treatments?

Yes, but there are no clinical studies to date that show what synergistic effects these combinations could have. The decision to use MiYOSMART lenses depends on the individual case.

9. In which cases should MiYOSMART not be used?

Strabismus, nystagmus (‘eye tremor’), keratoconus (cone-shaped deformation of the cornea) or other conditions that can affect myopia management should be clarified in advance. MiYOSMART lenses should not be used in these cases.
