Earlier in 2011, Optometrist and specialist contact lens fitter Jagrut Lallu announced the first myopia control clinic in New Zealand. In this in practice article we catch up with Jagrut as he explains the options for controlling myopia (short sightedness). He covers three options; namely, Orthokeratology, soft contact lenses and a specially designed spectacle lens. More information can be found at www.orthokme.co.nz or 0800 ORTHOK
The standard rate that 7 year-olds go down (from zero diopters) is about 0.8 diopters per year. Each person (at 20/40) should be informed of this issue, before any minus is used. This data comes from studies in Singapore with N = 800, so it is accurate. The child's nose-on-page creates the problem -- in the first place. Care with the child's reading habits would be in order.

I understand that if a "plus lens" is worn when the eye is at 20/40, and -3/4 diopters, a person can slowly clear his Snellen back normal (change refractive status by +3/4 diopters). Is that correct?
