Markus was wearing his troubled face when he was playing his Double Bass

Markus Van Horn is a very busy professional Double Bassist, specialising in Baroque, classical, and contemporary music. Markus plays with ensembles including the, City of London Sinfonia, London Sinfonietta, Orchestra of St John’s, London Mozart Players, Academy of St. Martin in the Fields, English National Opera, English National Ballet, Birmingham Royal Ballet, Britten Sinfonia, Opera 80, London City Ballet, Orchestre Révolutionnaire et Romantique and the Orchestra of the Age of Enlightenment. He has also played in principal roles with Royal Liverpool Philharmonic, Scottish Chamber Orchestra and Opera North.


A full-time varifocal wearer, Markus began experiencing problems focusing at music stand distance. He mentioned this to his local optician when he went for his regular eye examination. His opticians prescribed an additional pair of single vision spectacles for music stand distance. A musician not only needs to see the music stand. He also needs to see the conductor clearly and his fellow performers. Markus contacted Allegro Optical Opticians, as the spectacles prescribed failed to provide him with clear vision at all the working distances he needed during his work.

Allegro came to the rescue

The team invited Markus up to Meltham in Holmfirth for a consultation. Then plotted a performers lens designed to take into account all his working distances. We also measured and plotted the area and angle of his visual field at each distance. Once that was complete we adapted the music stand distance to give Markus as wide a field at the stand distance to enable him to see two full pages of sheet music, thus making it easier for him to concentrate on playing rather than seeing. As Markus lives in London we posted his new glasses to him a couple of weeks later, Just before Christmas.

Markus took a few weeks for his eyes to fully adjust to the new lenses. Learning exactly where each area is and developing his muscle memory. Markus now says  “The new lenses have really helped make the music clearer on the page and are of immense benefit when the lighting is poor. I am very pleased with them


Musicians can present an optometrist or dispensing optician with a great many challenges. Mainly because of their working distances and the varying positions of their visual field. As musicians ourselves, we’re able to ask the musicians the right questions, and to interpret their answers. Using our combined optical and musical skills we are able to address and resolve the many visual problems encountered by older musicians.

As a specialist optician, our team at Allegro Optical are able to produce individual solutions to suit many musician’s needs. This service is not available anywhere else. We approach the problem in a completely different way, looking at it from the musician’s perspective. Our unique design of lenses which will solve their individual unique problems. We have built up a considerable following among musicians and performers as a result.

It’s been less than twelve months since we opened our brand new practice in Meltham and we’re already getting noticed. Not only has the Allegro Optical Opticians been shortlisted for the Yorkshire and Humberside Federation of Small Businesses, Celebrating Small Business Awards, for the Start-up Business of the Year category.
