If you have regular eye checks and have been given the all clear on your vision, the picture above may cause a slight degree of irritation.
But for sufferers of glaucoma, the image above provides a glimpse into the lives of those who have to deal with the condition on a day-to-day basis.
Sight threatening condition
Throughout World Glaucoma Awareness Week, Specsavers Orpington are promoting the iomportance of regular eye tests in order to avoid the sight threatening risk posed by glaucoma.
Orpington currently has a high prevalence of glaucoma, with the number of newly reported cases of the condition being significantly higher here than the national average.
Avoid permanent damage
Store director, Shahen Raj, says: 'The image is a really salient one because although it's not 100% accurate, it does go some way to showing the sort of visual impairment that glaucoma sufferers experience.
'Glaucoma is one of those conditions that can go undetected for a long period of time and will often only show real symptoms once it's caused lasting damage to your eye sight. This therefore highlights the importance of ensuring people continue to come for their regular eye checks to help managed eye conditions as early as possible and enable us to provide the best treatment to prevent permanent damage to your eyes.'
