Biotic Telescope on Lens May Not Prevent Wider View

"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," according to a post on MedicalNewsToday. "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)."
