Our eyes aren’t exempt from wear and tear, and taking care of them is just as important as any other aspect of health. Our eyes naturally change with age. And, while some changes are harmless, others can be warning signs of eye conditions, such as cataracts and glaucoma.
You may be tempted to wait until your next regular check-up to get these symptoms looked at or ignore changes to your vision in the hope that things will improve on their own. But it’s important to see an optician as soon as you notice anything unusual. If left untreated, some eye conditions can increase the risk of vision loss.
The Royal National Institute of Blind People (RNIB) estimates that around two million Brits are living with sight loss – largely due to conditions like macular degeneration, diabetic retinopathy, and ocular hypertension.
With this in mind, we’ve partnered with Boots Opticians to bring you 11 signs of eye conditions that you shouldn’t ignore.
Note: If you’re experiencing any of the eye changes mentioned here, it’s important to book an eye test.

1. Blurred vision
Blurred vision is one of the most common symptoms of eye conditions. It can make seeing detail more difficult, and cause images to lose sharpness and definition.
Blurred vision differs from cloudy vision (when images look obscured or ‘milky’) and double vision (seeing two images of a single object). It can occur in one or both eyes and affect either your peripheral or central vision.
Experiencing temporary or occasional blurred vision is often just a sign that your eyes are tired. However, according to Boots Opticians, sudden blurred vision or blurred vision that doesn’t go away may signal eye conditions such as glaucoma, myopia, age-related macular degeneration (AMD), and diabetic retinopathy.
2. Flashes and floaters
Flashes and floaters are small dots or squiggly lines that appear in your vision. They’re often clearer if you stare at a light, solid-coloured surface.
It’s normal to see flashes and floaters (small dots, specks, lines, or cobwebs) in your vision from time to time, particularly in later life. Usually, they aren’t serious and are the result of a harmless process called posterior vitreous detachment (PVD), where the gel inside your eye changes. PVD is so common that 75% of people over 65 are affected by it. Flashes and floaters can also occur for no obvious reason.
However, in some circumstances, flashes and floaters can signal a more serious eye condition, so it’s important to always get it checked out.
According to Boots Opticians, experiencing a sudden increase in flashes and floaters, shadows in your peripheral vision, or floaters that appear after eye injury or surgery can be a sign of a retinal tear or detachment. In these cases, it’s important to seek urgent advice from your optician, GP, NHS 111, or go to A&E. If left untreated, retinal detachment can lead to permanent vision loss.

3. Headaches
Headaches can feel different depending on their cause. You may experience a dull ache or sharp pain behind the eyes or in your temples. Headaches can come and go quickly and, if there’s no underlying issue, will often go away with over-the-counter medications.
However, if the pain doesn’t go away or you’re experiencing regular headaches, it could be a sign of eyestrain or in some cases, an underlying eye condition.

4. Light sensitivity
Our eyes are naturally designed to handle varying degrees of light. However, light sensitivity, also known as photophobia, can make everyday light conditions seem too bright; causing discomfort or even affecting how well we see.
Experiencing mild photophobia is normal – for example, when you walk outside after watching a film at the cinema or when first waking up to sunlight in the morning. However, photophobia that lingers may be a sign of a more serious eye condition. Some eye conditions can cause inflammation or make it more difficult to adapt to changes in light.
Eye conditions that can cause light sensitivity include cataracts, uveitis, glaucoma, keratoconus, and corneal abrasions (a scratch on the eye).
5. Eye pain
Depending on its cause, eye pain may present as a sharp, aching, or throbbing sensation. It can also be described in terms of where it hurts – for example, behind the eye or in the eyelid.
Many eye conditions are painless, but some can cause eye pain. For example, a rare and particularly serious form of glaucoma, called angle-closure glaucoma, can cause severe eye pain due to a buildup of fluid within the eye.
Eye pain can also be caused by keratitis, a scratched cornea, dry eye syndrome, and eye injuries. Being able to explain where your eye hurts can often help your optician determine the cause.
Eye pain differs from the irritation you may feel if you get a piece of dirt or eyelash stuck in your eye, or eye strain caused by staring at a computer screen all day. In these cases, your eye(s) will usually feel better once the dirt or lash is out of your eye, or after you’ve taken a substantial screen break.

6. Dry eyes
Dry eyes can feel itchy, sore, gritty, red, blurry, sensitive to light, or more watery than usual. It may also be uncomfortable to wear contact lenses.
Experiencing occasional eye dryness is usually nothing to worry about – particularly if symptoms respond to over-the-counter eye lubricants. However, chronic eye dryness that causes discomfort or affects daily life shouldn’t be ignored. Dry eye syndrome is a condition in itself, but it can also be caused by other eye conditions such as blepharitis, or by laser eye surgery, wearing contact lenses for extended periods, or high screen time.
Eyes get dry when the eyes aren’t producing enough tears, or tears dry up too quickly. For this reason, it’s more common in later life, when the eyes naturally produce fewer tears due to hormonal changes.
According to Boots Opticians, dry eyes affect around 15-33% of people over 65. This is particularly true of women because menopause causes oestrogen and androgen levels to drop. In fact, dry eye syndrome is one of the most common eye conditions caused by menopause.
7. Changes in colour perception
Colour vision deficiency, also called colour blindness, is where you see colours differently to most people or have difficulty telling colours apart.
Some people are born with colour vision deficiency, but it can also develop at any age. Colour blindness can occur on its own or be caused by other eye conditions, including glaucoma, cataracts, and age-related macular degeneration (AMD).
For example, difficulty distinguishing between blue and yellow colours is often linked with early glaucoma. And many people with AMD find that colours appear more dull, dark, and less vivid.

8. Night blindness
Just as with daily light changes, our eyes are designed to be able to handle low-light conditions. To do so, the pupil expands to take in as much light as possible to allow us to see in low-light environments.
However, some eye conditions can impact the eye’s ability to absorb or process light and make it difficult to see at night or in dimly lit places.
Examples of eye conditions that have been linked with night vision problems include glaucoma, cataracts, nystagmus, and retinitis pigmentosa (gradual degeneration of the retina).

9. Peripheral vision loss
Peripheral vision loss, also known as tunnel vision, makes it difficult or impossible to see objects that aren’t directly in front of you. Peripheral vision loss can affect one or both eyes at the same time and may make you feel dizzy or unsteady when walking or standing.
Temporary peripheral vision loss can be caused by migraines. However, eye conditions that damage the eye(s) can lead to permanent peripheral vision loss, if left untreated. Some of the most common eye conditions linked with peripheral vision loss include glaucoma, retinal detachment, diabetic retinopathy, and optic neuritis.
Peripheral vision loss can also range in severity. For example, beginning in the outermost angles of your vision and creeping inward over time.
10. Red eyes
When our eyes become inflamed or irritated, the blood vessels expand, causing the white parts of your eye to appear red or pink. Redness in one or both eyes can have various causes, including allergies, smoke, or pollutants in the air.
However, if you suddenly develop red eyes or it’s causing you discomfort, it could be a sign of an eye condition. According to Boots Opticians, if your eye is red and painful, it could be caused by conditions including uveitis, glaucoma, corneal ulcer or a scratch to the cornea.
Final thoughts…
Our eyes naturally change with age. However, while some eye changes are harmless, others can signal more serious eye conditions. If left untreated, these can increase the risk of vision loss, so it’s important to know what signs to look out for and to speak to an optician if you notice any changes.
