The eye conditions that afflicted three popular US presidents have been highlighted in a new health campaign.
In a bid to drive home the importance of regular eye tests, the American Academy of Ophthalmology pointed out that Abraham Lincoln, Theodore Roosevelt and Woodrow Wilson were struck by eye problems.
The group noted that Lincoln suffered from strabismus, which meant he could not look a person straight in their eye and explains why his left eye seems to roll upward in some portraits.
Roosevelt, on the other hand, is reported to have been partially blind in one eye after receiving a blow during a boxing match. Medical historians have speculated that this was due to an undiagnosed detached retina.
In addition, Wilson was stuck by a haemorrhage of the retina before he became president and became almost blind in his right eye, although his vision later improved to some extent.
Last month, Dr Aaron Weingeist, an ophthalmologist in Seattle and a clinical correspondent, said people should ensure they have regular eye tests to protect themselves against a number of conditions.
