A police call handler's life has been transformed by glasses which make numbers appear as if in 3D.
Claire Curtis thought she might have to quit her job at Leicestershire Police headquarters, in Enderby, when she learned she had the rare condition dyscalculia.
However, an optician in Market Harborough has provided her with glasses fitted with newly developed lenses which make numbers stand out clearly.
The 49-year-old, of Hinckley, said it was wonderful she was able to continue in her job, directing officers to emergencies.
She said: "The change has been unbelievable.
"I was really struggling with numbers. I would hear them in a different order and I couldn't read them at all.
"It was becoming a real problem and was stopping me doing my job.
"The new lenses have allowed me to read the numbers far more clearly.
"They leap off the screen at me and now I am confident in my ability to do the job. It's incredible."
The glasses were supplied by Davis Optometrists, in St Mary's Road, Market Harborough.
Kim Durden, a partner optometrist at Davis, said: "Dyscalculia is a condition that affects the ability to acquire arithmetical skills. It's like dyslexia for numbers.
"People with dyscalculia may have difficulty understanding simple number concepts, lack an intuitive grasp of numbers or have problems learning number facts and procedures."
