Doctor issued urgent warning over eight eye symptoms that could be a sign of a serious issue

A doctor has highlighted concerning symptoms that could signal serious vision problems. Dr Russell Lazarus has outlined eight eye issues that should never be overlooked as they can lead to 'sudden damage to your eyes' or, in extreme cases, 'complete and permanent blindness'.

He emphasises the importance of recognising the signs and symptoms of various severe eye conditions, so you can inform your optician promptly. Fortunately, most of these eye conditions can be treated or managed effectively if caught early by a healthcare professional.

While the thought of vision issues may be daunting, it's vital to get any worrying symptoms examined immediately. Dr Lazarus points out that one indicator of a potential issue is experiencing sudden blurry or distorted vision.

He advises: "If you experience sudden blurriness or a distortion in your vision, like a straight line that appears wavy, consult your eye doctor immediately. Sudden blurry vision can affect either your peripheral vision or in your central vision, and can be a sign of many very serious eye conditions."

Keep a lookout for swelling around or in the eye itself, as it's another critical sign pointed out by experts. While most swelling results from an injury or allergic reaction and tends to subside with time, persistent swelling is a cause for concern, says Dr Lazarus, reports the Mirror.

They emphasise, "If swelling persists over a longer period of time, this may be a sign of a more serious issue."

Persistent headaches are another symptom worth your attention. If you find that typical painkillers aren't effective against a prolonged headache, Dr Lazarus suggests it's crucial to consult your eye doctor straight away.

Moreover, red, irritated eyes should prompt a check-up as they may indicate a grave eye condition. Increased sensitivity to light is also a symptom to be vigilant about.

Moreover, pay heed to floaters – those small lines, dots, or webs moving through your field of vision. Dr Lazarus advises, "If you experience a sudden onset of floaters, or more floaters than you're accustomed to, you should contact your eye doctor immediately."

These visual disturbances are more noticeable against plain or light backgrounds, such as computer screens, pale walls, or the sky, and while a few are normal, an increase warrants immediate medical attention.

Night blindness is another symptom to keep an eye on. If you're having difficulty seeing in dim light, it could indicate a problem with your vision.

Conditions such as Glaucoma and Cataracts can affect your night vision, so it's crucial to have regular eye checks. Dr Lazarus also advises getting any flashes in your vision examined by an optician.

While sudden flashes can be common as we age due to the 'vitreous fluid tugging or rubbing on the retina, at the back of your eye', he warns that: "If you notice lights that can appear as lightning flashes, flashing bulbs or bright stars, these can be the first sign of injury or other eye conditions."
