Seven subtle signs of eye cancer you should never ignore, according to expert
Sore eyes are often dismissed as a result of too much screen time or general fatigue, but they could be a warning sign of a potentially deadly cancer.
According to Cancer Research UK, around 880 people in the UK are diagnosed with ocular cancer each year, with approximately 130 losing their lives to the disease. Despite its rarity, accounting for less than one per cent of all new cancer cases, many of its symptoms remain largely unknown, Bristol Live reports.
On the occasion of World Cancer Day, February 4, an eye expert is urging people to pay closer attention to changes in their vision that could signal a serious health issue.

Neil Laird, Specialist Optometrist at Pure Optical, warns that many dismiss eye changes as a result of ageing, stress, or excessive screen time.
"Many people tend to overlook changes in their vision or the appearance of their eyes, assuming it's simply a result of ageing, stress, or just using their devices for too long," he says. "Yet, identifying these subtle signs early on can be crucial. A simple visit to an optometrist could not only protect your eyesight but also your overall health."
He said symptoms to watch out for include:
Blurred vision or sudden eyesight changes – Struggling to focus or experiencing double vision may point to an underlying issue.
Dark spots on the iris – Unexplained growths or enlarging patches on the coloured part of the eye should be examined.
Flashes of light or shadowy shapes – These disturbances could signal retinal problems or tumours within the eye.
Lumps or swelling around the eye – Any persistent swelling or new lump should receive medical attention.
Redness or irritation – If redness persists despite treatment, it’s important to seek professional advice.
Bulging or changes in appearance – A protruding eye or asymmetry could indicate a deeper problem.
Loss of peripheral vision – Gradually narrowing vision may be a sign of a serious condition.
The expert added: "Many of these symptoms can resemble harmless conditions, which is why they can be easily dismissed. However, if something seems off or continues longer than you’d expect, it's always wise to have it examined. Eye cancer doesn't have to mean a life sentence if detected early."
Catching eye cancer early can significantly improve treatment success, with about 95% of patients in England surviving at least a year after diagnosis. That’s why experts stress the importance of routine eye exams—every two years for most people, or annually for those at higher risk.
Family history plays a role too, as having a first-degree relative with melanoma increases the risk of developing eye cancer by 30-50 percent.
Neil Laird, Specialist Optometrist at Pure Optical, also warns about the dangers of UV exposure. “Shielding your eyes from UV radiation is crucial, as UV exposure can lead to uncommon forms of eye cancer, like conjunctival melanoma,” he explains.
"To minimise this risk, wear quality sunglasses that block UV rays or add a layer of UV protection to your everyday glasses. World Cancer Day is a crucial reminder to stay vigilant about our health.
"While eye cancer may not receive as much attention as other types, its effects can be equally significant. This year, make it a point to focus on your eye health by booking a routine eye exam or seeking advice from a professional if you observe any unusual changes."
