By Emma Innes PUBLISHED: 05:31 EST, 2 September 2013 | UPDATED: 11:44 EST, 2 September 2013 A ten-year-old schoolgirl had her life saved by a routine eye test which showed a tumour the size of a golf ball pressing against her brain. Lauren Uncles went to her local opticians to get some prescription sunglasses for a family holiday in Cornwall on August 21. But during her eye examination, optometrist David Strachan spotted swelling behind her optic nerve. Lauren Uncles (pictured with her mother Teresa) was diagnosed with a brain tumour after her optician noticed a problem during a routine appointment. Thanks to the optician, she rapidly underwent life-saving surgery
