Dr. Joshua Silver, a retired Oxford University professor, has introduced a type of glasses that can be adjusted directly by users without the eye center.

After more than 20 years of research, the British scientist has successfully built this type of glasses, which can be used for both nearsightedness and farsightedness. The thickness of the new glass can be adjusted by injecting small liquid particles into the bags in the middle of the glass.

Once the lenses have been adjusted, users only need to remove the syringe and wear normal glasses. This invention could bring light to millions of people in the third world, areas that lacked eye specialists.
