User-Adjustable Glasses

Posted by timothy on from the would-like-to-test-these dept.

DrLudicrous writes "An Oxford University professor has come up with a way to manufacture adjustable glasses. The lens is made up of silicone oil, which when added or removed changes the curvature, and thus the strength of the lens. Apparently, these are inexpensive enough to distribute to the poor people's of rural Ghana, who do not have the opportunity to see a doctor, let alone afford conventional glasses."

    Don't forget to donate your old glasses to charity as well!

      The eyeglass donation places will be able to make good use of your frames.

      The lenses are often discarded , since few people have the exact same vision.

      Christ, these were on Tomorrow's World about 6 years ago, and that particular "new technology" program is usually about 2-3 years off the pace.

    Yes, it's very possible to cause harm to your vision by wearing glasses that are either too strong or too weak. Any optometrist will tell you that the drugstore rack reading glasses should be banned. Another less obvious hazard is the quality of the materials often used to make these glasses. The cheap ones really do not have shatter-proof lenses. Not a good thing.

    Hmm, I seem to remember seeing these on "Tommorrow's World" some years ago; exact same invention, and probably the same inventor.. I don't recall.
