A study by scientists at Schepens Eye Research Institute shows that a bioptic telescope on one lens of a pair of glasses used to magnify traffic signs and lights may not prevent the wider view of the road with the second eye. The study results, which will be published in the May 2011 Archives of Ophthalmology, are the first evidence that--under more realistic viewing conditions than in earlier studies--the second eye can detect objects in the area obscured by the magnification effect of the telescope (called the ring scotoma).
