A lot of kids are affected with nearsightedness or myopia that interferes with several actions like learning in school. With age, these children may face progressive myopia that may worsen with time. Various strategies have been suggested to stop or slow progressive myopia in children:

Using Hard Lenses: Studies have been indicated to suggest that RGP or GP or rigid gas permeable lenses could control myopia. The rigid lens acts as a splint that fortifies the eye surface without influencing the shape of the cornea. The lenses minimize progression of myopia better than soft lenses or specs. However, the idea could not be relied upon due to inadequate variable control, poor participant selection and incomplete follow up.

The CLAMP or Contact Lens and Myopia Progression made a 2004 study with over 100 kids aged between 8 and 11 years over 3 years. The wearers wore soft and GP lenses. The researchers estimated that myopic kids have elongated eyeballs with heightened cornea. The long axial length is responsible for blurred vision.

Wearers of GP lenses showed less of myopic progression, temporarily. The eyes of GP lens wearers grew long like those of soft lens wearers, and as GP lens does not stop or slow progressive myopia, there was no permanent myopia reduction.

One of the difficulties of GP lenses is that it retards myopia. This is proved not by understanding how people would do without treatment. In fact, practitioners cannot suggest that your kid will progress to a prescribed -9 diopters unless they had not worn the gas permeable lenses to correct or control myopia. It can also be suggested that myopia is not an inherited condition, although if most family members are myopic, the child may acquire it as well.

Myopia Undercorrection: Eye specialists tried myopia undercorrection to reduce focusing strain which is said to lead to progressive myopia. However, the study was statistically imperfect and hence conclusions could not be made. There were no considerable differences between the fully corrected patients and the undercorrected ones. Other studies found that undercorrection increased progressive myopia.

The COMET or Correction of Myopia Evaluation Trial tested the viability of using progressive or bifocal spectacles for alleviating focus. The studies indicate that progressive lenses slowed the myopic progression, when compared to single vision lenses, although the rate is a tiny one.

Therefore myopia undercorrection has not been proven for reducing the progress of nearsightedness in kids.
