SWISSCOAT offers the Myopia control and monitoring lenses that can slow down the rate of progression for your child. It is specially design for the active 8 to 16 years old children.
SWISSCOAT Myopia Control lens need to be prescribed by professional optometrists and to have always at least every 6 months check up and monitor by your optometrists in order to achieve the best result in the control of the shortsightedness. SWISSCOAT Myopia control and Monitoring lenses :
MYO ProTECH
Know More About Peripheral Defocus Lenses and know more about how can myopia be controlled
With standard single vison lenses, the central zone works fine and provides clear distant vision, but the lens periphery always projects the image behind the retina, resulting in hyperopic defocus.
From various clinical studies, it is believed that peripheral retinal hyperopic defocus would send signal to elongate the eye ball which may cause myopia progression.

SWISSCOAT MYO ProTECH Myopia Monitoring lenses provide different correction curve to minimize the over correction.
In normal circumstance, when we are looking at objects, image would be focused on macular region (central retina), but when the light ray is from periphery, it passes through the lens periphery and projected onto peripheral retina, hyperopic defocus would be resulted.
Peripheral defocus lens (MYO ProTECH in this case), power decreases towards lens periphery from optical centre, which helps compensate for unwanted peripheral hyperopic defocus, and therefore may help retarding myopia progression theoretically.
to minimize the over correction.
the edge with different slope design.
Keep the distance power extend to the near vision zone for reading.
Peripheral Defocus
Hyperopic defocus, image focus behind retina
Myopic defocus image focus in the front of retina
When compare with standard single vision lens, peripheral defocus lens is more effective in retarding eye-ball elongation

MYO ProTECH Lens Design Principle
- Aspherical
- Clear Vision and stable optical zone in the center part (8-10mm)
- Correcting defocus from optical center to periphery
- Far Distance power is extended to reading zone at the lower part of the lens with inset
- Defocus option available in 0.25 light , 0.50 standard , 0.75 max
- 0.75 is the strongest peripheral defocus power, maximum defocus could reach 1.75D ( 20mm away from optical zone )
Each MYO and Kids ProTECH is infused with 5 major SWISSCOAT unique technologies
StressFree - the blue light protection proven by The Hong Kong Polytechnic University
Hong Kong is a city that is drenched in blue light. With flashy monitors everywhere and the ever increasing usage of electronics such as smartphones, their eyes are susceptible to more blue light than most other cities, and could drastically affect their eye health.
There is a way to stem the tide. With SWISSCOAT’s StressFree coating features effective protection against high energy blue light. In a commissioned research done by The Hong Kong Polytechnic University1, it is proven that SWISSCOAT’s StressFree coating offers the following benefits.
1. Effectively filters high energy blue light
2.Does not hinder color and contrast sensitivity
3.Does not affect night vision

ADVANTAGES
• Relieve the lengthening of ocular axis • Correct Myopia • Comfortable • Suitable for Myopia wearer that from 6 to 16 years old
FITTING TIPS• Same as progressive lens • Fitting height required • Mono PD required • Keep the pupil position at least 15mm to the rim of nasal • PD difference from frame PD to client PD within 5mm • Max power for 025 design: -2.00D (Over -2.00D) • Max power for 050 design: -3.00D (Over -2.50D) • Max power for 075 design: -4.00D (Over -3.00D)
Kids ProTECH
Children’s eyes are bombarded with damaging light sources that surround us every day. From the sun’s UV rays to the tiny text in textbooks, there is always an eye-damaging source nearby. SWISSCOAT combines years of experience and expertise to design the all-new Kids ProTECH, the children myopia control protective lenses that not only controls myopia progression in your child, but also protect their maturing eyes from UV, blue light, and impact resistant protective properties.
Each Kids ProTECH lens is infused with 5 major SWISSCOAT technologies:
- StressFree Anti-blue light coating
- Myopia Control design
- Armour UV++ protective lens ( 100% UV protection )
- 5 times stronger Impact Resistant coating
- Clearview HD coating
• Relieve the lengthening of ocular axis • Correct Myopia • Comfortable • Suitable for Myopia wearer that from 6 to 16 years old
FITTING TIPS• Same as progressive lens
KidsPro
SWISSCOAT KidsPro has all these benefits to the children who choose to wear Myopia Control Lenses:
- A shorter corridor
- A wider reading zone
- A wider far vision zone
- A softer design compared to conventional progressive lens. Eye-point Technology ensures the softest lens design for every vision zone.
With KidsPro you can fit into any small children frame, the minimum fitting height is 17mm. The short corridor enables an easy transition between the far vision zone and the reading zone for the children. Aspheric in all its vision zones, KidsPro is the thinnest and lightest possible lens to wear.
Pupil Distance Measurement
- When using a pupilometer for measuring pupil distance, verify the result though a manual test
- If a pupilometer is not available
- Position yourself at the child's eye level
- Make the pupil canter on the demo lens in the frame
- Place the demo lens on the centration chart and read the monocular PD
Fitting Height Measurement
Be aware that the fitting height can differ from eye to eye
- Position yourself at the child's eye level
- Make the pupil center on the demo lens in the frame
- We recommend a minimum fitting height of 17mm
Cut-Out Confirmation
- Position yourself at the child's eye level
- Make the pupil center on the demo lens in the frame
- We recommend a minimum fitting height of 17mm
Lens Verification
- If lenses are not marked, restore the marking with the KidsPro sticker marker
- Fit the frame with the glossed lenses on the patient and verify that the fitting cross is aligned with the pupil center
ADVANTAGES
• Relieve the lengthening of ocular axis • Correct Myopia • Comfortable • Suitable for Myopia wearer that from 6 to 16 years old
