Long-sightedness

Long-sightedness is where you find it hard to see things nearby, but you can see things far away clearly. It’s a common condition and wearing glasses or contact lenses can usually correct your vision.

Long-sightedness is also known as hypermetropia or hyperopia.

Check if you have long-sightedness

Long-sightedness can happen at any age, but often affects people over 40.

Symptoms of long-sightedness include:

• finding it hard to see nearby things, for example, words and pictures in books or on screens may look fuzzy
• being able to see things more clearly when you move them further away from your eyes
• tired eyes after tasks that involve looking at something closely, like reading or working at a computer
• headaches

What happens during an eye test

To check if you or your child is long-sighted a specialist called an optometrist will usually do an eye test.

You’ll be asked to look at lights or read letters while different lenses are placed in front of your eyes. This helps the optometrist find out how well your vision is working.

The optometrist will usually shine a light into your eyes to check the back of your eyes are healthy. They may give you eyedrops which helps them to get a better look.

Treatments for long-sightedness

Glasses and contact lenses

Long-sightedness can usually be treated with glasses or contact lenses.

These help your eyes focus correctly so you can see nearby objects clearly.

Your optician will give you advice on the best options to treat your long-sightedness. Contact lenses are usually only suitable for adults and may not be suitable for everyone.

Laser and lens surgery

Some people with long-sightedness may be able to have laser eye surgery or lens replacement surgery to correct their vision. Both types of surgery are carried out while you are awake, using local anaesthetic, so you will not feel any pain.

Laser eye surgery is where high-energy beams of light (lasers) are used to reshape the surface of the eye (the cornea) to correct the way your eye focuses.

Lens surgery is where the lens inside your eye is replaced with a plastic implant to correct your vision.

Ask your optician if laser or lens surgery may be options for you. These treatments are not usually available on the NHS.

Causes of long-sightedness

Long-sightedness happens when the eyes cannot focus properly.

This can be because of:

• the shape of your eye
• the shape of the front layer of your eye (the cornea)
• the lens inside your eye has become stiffer, usually due to aging (presbyopia)

Long-sightedness is often passed on from your parents and cannot be prevented.

It can also be caused by other conditions like diabetes and eye cancer, but this is very rare.

Complications of long-sightedness

If left untreated, long-sightedness may cause other vision problems.

Young children with severe long-sightedness are more likely to develop other eye problems, including lazy eye and squint .
