ADJUSTABLE FOCUS GLASSES MADE, as reported in news@nature and ScienceNOW 3 April 2006. Scientists at the University of Arizona, Tucson, have developed a liquid crystal lens that increases its magnifying power when a small electric current is applied to it. The lens could be used by people who currently need reading glasses or bifocal lenses to see close objects. The great advantage of such a lens is that people who need glasses for close work donít need to change glasses, or rely on a small part of their visual field as they do with bifocals. As about 90 percent of the population eventually needs glasses for reading and other close work, the scientists see a great future for their invention.
ED. COM. During his recent visit to the UK John Mackay debated well known evolutionist Dr Steve Jones (London University Biology Prof)on a BBC program hosted by Jeremy Vine. During the interview Steve Jones said that he had taken off his glasses and could no longer see and that proved the human eye could not have been designed, therefore naturalistic evolution was the only acceptable explanation for such a poor design. The fact that the human eye lens often becomes stiff and unable to change focus in later life is a reminder that our bodies are going downhill, not evolving upwards, and some parts degenerate faster than others. Thus the human eye is a good reminder of the Biblical history of the world Ė from designed perfection to degeneration, not simple to complex as the evolutionists claim. The fact that it takes creative optical engineers, who understand the properties of materials and the laws of physics, to design a lens that does the same thing as a healthy human eye lens, is evidence that the biological lens took creative design, not chance random processes to build. As someone who wears bifocals and has to go through life with part of the visual field out of focus this editor is pleased to see the results of creative design on artificial lenses in this life, and looks forward to eyes that wonít degenerate in the next life.
