The NHS has warned people who wear contact lenses or glasses that they may be at risk of a common eye condition without realising it. Talking about astigmatism, it explained that the condition can often cause "blurry vision."

Because of this, "it's usually treated using glasses or contact lenses." However, it further warned that you could have another condition which is closely linked to astigmatism - the very reason you need to wear contact or glasses - and it's best to get your vision checked out often as the earlier you catch it, the better.

If you have astigmatism, this means that your eye is shaped more like a rugby ball than a football. Because of this, light is focused at more than 1 place in the eye.

The main symptoms of astigmatism are:

• blurred vision


• headaches


• eye strain - you may notice this after concentrating for a long time, such as when using a computer

What are the treatments for astigmatism?

Health experts explained that while this eye condition does not always require treatment, certain measures can help such as wearing glasses, contact lenses and even undergoing laser surgery. This is, of course, not for everyone, and there are many pros and cons for different astigmatism treatments.

Treatment Pros Cons

Glasses	the cheapest option may be available free or discounted on the NHS	could get lost or broken
Contact lenses	choice of soft or hard lenses can be a good choice if you're active may be free or discounted on the NHS	may not be suitable for everyone risk of eye infection through poor contact lens hygiene
Laser eye or lens surgery	may be permanent may be better for people with more severe vision problems	risk of complications during or after surgery not available on the NHS can be expensive possible side effects

Astigmatism often occurs together with short-sightedness or long-sightedness. If it affects only one eye, it can sometimes lead to a lazy eye, which occurs when vision doesn't develop properly. The NHS noted that detecting it early is important so that treatment can be started as soon as possible.

When was your last eye test?

The NHS suggested that if you or your child have symptoms of astigmatism or you or your child have not had an eye test in 2 years, you should go to your optician. The NHS warns: "Astigmatism can be linked to an eye condition called keratoconus. So it's important to get regular eye tests."

What is keratoconus?

Specsavers UK explained: "Keratoconus happens when the cornea (the round, clear front part of the eye) starts to weaken and thin at its centre, causing it to become irregular (or coned) in shape. Eventually, this prevents the eye from focusing properly, which causes poor vision."

Keratoconus often affects both eyes, and the symptoms can differ from person to person. In its early stages, keratoconus symptoms can include:

• Mild blurring or vision




• Slightly distorted vision, with some parts clear and some parts blurry




• Increased sensitivity to light and glare

In a small number of cases, keratoconus continues to progress. Symptoms include:

• Very blurry and distorted vision




• Eye pain




• Increased nearsightedness or astigmatism




• Not being able to wear contact lenses, as they no longer fit properly

In the early stages, your optometrist can recommend glasses or contact lenses as a treatment option. If the condition progresses, you may need to be referred to a corneal specialist to explore further treatment options based on the severity of your keratoconus.
