Myopia control eyeglasses lenses. It is an innovative spectacle lens for myopia control, and designed for teenagers under 18. It uses three core technologies to control myopia progression, and provides clear vision and myopic defocus simultaneously at all viewing distances.
Myopia defocus control technology is the answer.
Well from the pictures above you can find — it can change the way light focuses on the retina between the central and peripheral retinal areas. Peripheral defocus theory suggests that this designs work at controlling myopia because they create that all important peripheral myopic defocus, interrupting the feedback loop for the eye to continue lengthening that is our bane in glasses and single vision lens wear.
1. Suitable for children and teenagers under 14 years old
2. Children’s glasses must undergo mydriatic optometry, and the diopter of
the mydriatic optometry shall prevail
3. During the optometry process, the eye position and adjustment function
must be checked, and the prescription should be adjusted according to the
adjustment function and eye position
4. Children with excessive accommodation and esotropia should not wear
defocus lenses (only 7% of patients with esotropia and myopia)
5. Defocus lenses must be fitted under proper correction, not undercorrection and over-correction
6. When fitting defocus lenses, you should choose a suitable frame
(preferably S-shaped adjustable nose pads), and process and assemble
according to the pupil height.
7. Frame width ≥ 45mm, frame height ≥ 30mm, and the amount of
displacement as much as possible ≤ 4mm
8. The lens must remain 12 mm in front of the eyes, with an 8-10 degree
forward tilt angle
9. Defocus lenses must be worn for a long time, regardless of any luminosity,
far or near
Processing precautions
1. Diopter detection and distinguishing
between left and right eyes.
2. During processing, the optical center is
mainly based on measured optics.
3. Wear it after processing. If there is a
deviation between the optical center and
the pupil reflection point, the frame
should be adjusted.
4. After the frame is adjusted, the
processing of the mark is carried out.
