New self-adjustable glasses


Child ViSion™ has developed self-adjustable glasses which the wearer is able to adjust until they can see clearly. These glasses are based on a fluid-filled lens technology that is similar to that used in the Adspecs, the original self-adjustable, fluid-filled glasses developed by Professor Joshua Silver. While the Adspecs were designed for use by adults, the Child ViSion™ glasses have been developed specifically for use by young people aged from 12-18. These glasses are small, light and attractive, and have been designed to withstand hard use in challenging environments. They have also been designed to enable mass-manufacturing to keep the cost of production as low as possible.

Perhaps the most important question is: do they work? Several recently published studies (which can be read hereand here ) have demonstrated that the process of self-refraction with the Adspecs can produce very good visual outcomes in teenagers when compared to the best possible techniques in developed countries.

We will be undertaking clinical trials of the Child ViSion™ glasses in mid-2013 in order to demonstrate their efficacy. After that, the next step will be pilot deployments in schools in developing world countries in order to test distribution models, followed by wider deployment of the glasses through partner organisations and government education systems.


How do you use self-adjustable glasses?

Self-adjustable glasses are designed for use in parts of the world where there are too few optometrists to screen patients and to prescribe custom glasses for refractive error. Self-adjustable glasses allow the wearer to adjust the lenses until he or she can see clearly. They are simple to adjust and can be dispensed by almost anyone with basic training.
Step 1: Check for poor vision

Perform a basic screening test for poor distance vision using the 'tumbling-E' illiterate vision chart.

Step 2: Adjust lenses

Turn the dials slowly on the side-arms until each eye can see clearly.



Step 3: Seal lenses

Press the buttons on the frame to seal the lenses in place, detach the adjuster tubes and prevent further adjustment.


Step 4: Remove adjusters

Unclip the adjusters from the side-arms and dispose of them safely. The glasses are now set and sealed and function like normal spectacles.

Step 5: Wear

Your Child ViSion™ Adjustable Glasses are ready for use.
