In Focus: What Is Refractive Error?

As we expand our ‘in focus’ series, we’re answering the question “what is refractive error?”.

Our ‘in focus’ series also covers glaucomacataracts diabetic retinopathy and, age-related macular degeneration.

Did you know that uncorrected refractive error is responsible for 39% of the 2 million people living with sight loss in the UK?

What is refractive error?

Refractive error is the name for a number of eye disorders that are the result of irregular eye shapes.

When light enters your eyes, the shape of your eye may prevent the light from focussing on your retina correctly.

So, the information that your brain receives may lack clarity, or your brain may work harder to correct the image.

As a result, you may experience some symptoms.

Types of refractive error

There are four types of refractive error:

⚫️ Myopia, or nearsightedness, makes it difficult to see objects far away.

⚫️ Hyperopia, or shortsightedness, makes it difficult to see objects close-up.

⚫️ Astigmatism can distort your eyesight for objects both far and near.

⚫️ Presbyopia can make it difficult to read or see detail. However, presbyopia develops with age and usually affects people over 40.

Symptoms of uncorrected refractive error

There are several symptoms of the condition, and you may experience some or all symptoms, or none at all.

⚫️ Blurry vision may make it difficult to see objects both near or far (or both).

⚫️ You may experience headaches as your eyes are working harder to focus and adjust.

⚫️ Your eyes may feel tired or strained as a result of trying so hard to focus.

⚫️ You may squint your eyes as your eyes are working hard to focus.

You may not necessarily realise that you are experiencing these symptoms at the time.

However, as some of the symptoms can indicate other eye conditions or general health conditions, you mustn’t self-diagnose.

You should attend your regular sight test to monitor these symptoms or treat any refractive error.

Do you know how often you should have a sight test?

Treating the condition

The treatment to manage refractive error includes wearing glasses, contact lenses or corrective surgery.

However, uncorrected refractive error (i.e. wearing the wrong glasses or an old prescription) means vision will remain poor.

That’s why it’s vital to wear your glasses or contact lenses if you need them!

As a result, you can help to avoid bumps and falls, ensure you can see the world around you clearly and prevent feelings of isolation.

You can keep your prescription up-to-date by attending your regular sight test and updating your glasses as advised by your optician.

If you have any concerns, you should speak to your optician.

Interesting Eye Facts

As we talk about eyes almost all of the time, we thought it’s time to share some interesting eye facts!

You don’t see with your eyes

Although we look at things with our eyes, we see an image with our brain.

When light enters our eyes and focusses on the back of the eye, millions of receptors receive information and send electrical messages to the brain.

These electrical messages contain colour, detail, contrast and movement.

Our brain then processes the information sent by our eyes, and we see an image as a result.

Your eye colour is not significant

Eye colour is due to the presence of melanin (pigment) in your iris.

The more melanin you have, the darker your eye colour.

Ultimately, your eye colour doesn’t affect your eyesight or eye health.

The iris in your eye is a muscle

Did you know that the iris is a muscle? It controls how much light enters your eye.

When our pupils get bigger or smaller, it’s the iris controlling it.

The pupil is a hole between your iris

Your pupil is the black hole in the middle of the iris.

Don’t worry though, it’s not the same kind of black hole that sucks everything in!

While the iris controls how much light enters your eye, the pupil allows the light to enter your eye.

Now that you know this interesting eye fact, you’ll notice it in every close picture of an eye!

20/20 vision doesn’t mean perfect eyesight

While 20/20 vision is thought to be “perfect eyesight”, it doesn’t provide the full picture of your vision.

For instance, it doesn’t indicate how well you can see up-close, whether you’re colour blind or whether you have peripheral vision.

Our 20/20 Vision

The inevitable quip of having 20/20 vision for 2020 has to be made – so here’s our perfect vision for 2020!

Firstly, before we explore our goal for 2020, we’re going to look at what 20/20 vision means.

What is 20/20 vision?

20/20 vision is a measurement of a person’s visual acuity 20 feet away from a test chart (which is American terminology).

Simply put, visual acuity measures how well you can see using the letter chart that your optician likely uses to test your eyes.

Although society associates having 20/20 as perfect vision, it’s possible to have even better visual acuity.

However, more suitable terminology is ‘normal vision’ rather than perfect.

Also, in the UK, 6/6 is the equivalent of 20/20 vision.

‘Perfect vision’ and eye health

Contrary to popular belief, it’s possible to have 20/20 vision and need glasses too!

Furthermore, visual acuity and eye health are not the same things, so it’s possible to have perfect vision and also an eye condition.

Our 2020 vision

Visioncall’s 2020 vision is to continue raising awareness of eye care to help us all see better and live better for longer.

Having a regular sight test is just one step of caring for your eyes.

Ultimately, eye care consists of proactive behaviours that can help maintain your eye health between visits to the optician.

It’s also vital to be aware of your family history (including your heritage) when it comes to eye health.

Your family history, age and lifestyle choices collectively are your risk factors for developing an eye condition.

That’s why our 2020 vision is to help raise awareness of eye care, so you know how you can help maintain your eye health.

Standards of Vision For Driving

Safety in winter conditions– and indeed all year round – also includes consideration of eyesight and driving.

Did you know that DVLA has ‘standards of vision for driving‘?

So, if you need to wear glasses or contact lenses to meet this visual standard, you must do so.

It’s illegal and dangerous to drive without your glasses if you don’t meet the standards of vision for driving.

DVLA launched its EYE 735T(eye test) campaign in 2018 to raise awareness of the visual requirements for driving.

Do you meet the standards of vision for driving?

EYE 735T is an easy and straightforward way to see if your eyesight meets the minimum requirements for driving.

Can you read a number plate from 20 metres?

Give it a try the next time you see a number plate!

Remember to wear your glasses if you need them – and if you struggle to read the number plate, it might be time for a sight test.

Do you have a health condition that may affect your driving?

If you have a health condition that can affect your driving, you must declare it to the DVLA.

You can find a list of conditions here with more information.

It’s essential to note that being at risk of developing some conditions may also need to be declared.

If you fail to declare a health condition that affects your driving, you can receive a fine or face prosecution if, as a result, you’re in an accident.

By considering whether your eyesight is suitable for driving is to ensure your own safety and of those around you, including pedestrians.

If you have any questions or concerns about your eyesight or eye health, you should speak with your optician.

why you should wear your glasses

If you need glasses but don’t always use them, we’re going to explore why you should wear your glasses.

Did you know that not wearing glasses is the leading cause of preventable sight loss?

Why you should wear your glasses

Wearing your glasses can help prevent eye strain, eye fatigue, headaches and potentially even your eyesight from deteriorating.

When someone needs help walking, they use a walking stick or zimmer frame – and glasses are the walking stick for your eyesight!

Wear the correct pair!

However, you should also make sure the glasses you use are your most up-to-date and correct pair.

This advice is particularly crucial if you need:

⚫️ One pair of glasses, but still have an older pair.

⚫️ A pair of reading glasses and a pair of distance glasses.

It’s essential to wear the correct pair for the relevant tasks so that your vision is as clear as possible.

For instance, wear reading glasses for close up tasks like reading and knitting, and distance glasses for driving or watching TV.

Wearing the correct glasses is a crucial step in how you can care for your eyes daily.

You can get an up-to-date prescription by having a regular sight test. Do you know how often you should have a sight test?

The benefit of wearing the correct glasses

Wearing the correct glasses is key to being able to see better and live better.

Your current prescription may be stronger than an old pair, which helps your vision to be sharper and more clear.

This is particularly important if you are living with a refractive error or eye health conditions such as cataracts, glaucoma, macular degeneration or diabetic retinopathy.

Wearing the wrong glasses (including an old prescription) can be just as harmful to your vision as not wearing glasses at all.

As a result, poor vision can increase your risk of falls and reduce your independence, which can cause physical and emotional damage.

If your glasses are from Visioncall, you can quickly identify the purpose and most current pair of glasses with our engraving.

So, next time you should be using your glasses, make sure you put them on!

Visioncall putting vision first

This World Sight Day, we’re going to look at why we should put vision first and how we drive awareness all year round.

Sight is one of the key senses that enables us to engage with and understand the world around us.

Naturally, sight is the sense that the majority of us most fear losing, and yet we’re unlikely to do something about it.

We prioritise visiting the dentist over the optician – but we should visit the relevant health professional as and when needed.

So, if you’re due a sight test, book an appointment with your optician now!

What’s World Sight Day?

The purpose of World Sight Day is to raise awareness of sight loss and blindness.

Unfortunately, eye care and eye health is an area of health that we often forget.

So, general awareness to improve sight is a positive thing, and that’s why this is a great cause to advocate.

Visioncall is proud to be part of the ongoing eye care conversation.

Visioncall participates in the Vision First conversation throughout the year

We actively take part in raising awareness of eye health and eyesight throughout the entire year.

We do this because we understand the value of better sight and that when a person can see better, they can live better.

On our blog, we constantly explore how to put vision first and care for your eyes– including how Visioncall can care for the eyes of those who can’t do it themselves.

Visioncall Daily Eye Care Guide

Visioncall’s eye care guide can help improve your eye health between visits to the optician!

Most importantly, our ongoing efforts are not exclusive to the people we deliver a sight test to.

We’re passionate about spreading the Vision First message to everyone!

We also recently took part in National Eye Health Week with a digital campaign, sharing tips and tricks to improve eye health.

The most essential and reoccurring advice throughout the year is to have a regular sight test.

Do you know how often you should have your eyes tested?
