Common Vision Changes and How to Spot Them

Post on 1st May 2026

Our eyesight is something many of us take for granted – until something changes. Vision can change so gradually that we barely notice them at first. You might find yourself squinting at your phone, struggling to read a menu in a dimly lit restaurant, or rubbing your eyes after a long day at your desk.

Does this sound familiar?  If yes, the good news is that vision changes, especially as we get older, are to be expected and are highly manageable. At Scrivens Opticians & Hearing Care, with over 85 years of experience in eye care, we believe that knowing what to look out for is the first step to looking after your eyesight.

Here’s your guide to the most common vision changes and how to spot them.

Blurred or fluctuating vision

Blurred vision is one of the most frequently reported eye symptoms and it can affect people of all ages. You might notice it when reading small print, when looking at a screen far away or trying to make out road signs while driving.

However, fluctuating vision, where your vision seems to shift between clear and blurry can be unsettling. This can sometimes be linked to dry eyes, changes in blood sugar levels, or eye strain.

If you notice your vision blurring regularly, even temporarily, it’s worth mentioning to your Optician at your next appointment, or sooner if it’s affecting your daily life.

Difficulty focusing for near tasks

Do you find yourself struggling to focus on close-up tasks, such as your laptop screen at work?

Difficulty focusing close-up tasks is a common sign that your vision may have changed. This is particularly common as we get older – a condition known as presbyopia, which typically begins to develop from around the age of 40. It happens as the lens of the eye gradually loses flexibility, making it harder to adjust focus quickly.

The reassuring news is that presbyopia is extremely common and very easily corrected with the right prescription glasses or contact lenses.

Struggling with glare

If bright lights, sunlight, or oncoming headlights at night are causing you more discomfort than they used to, this could be a sign that something has changed with your vision.

Increased sensitivity to glare can be associated with a number of eye conditions, including dry eye syndrome and cataracts. If you find yourself squinting more in bright conditions, avoiding well-lit environments, or struggling with night driving, it’s worth getting your eyes checked.

Anti-reflective driving lenses or light intelligent lenses (the kind that darken in sunlight) can make a significant difference – ask your Scrivens optician about what might suit you best.

Frequent headaches or eye strain

Headaches at the end of a long day and tired or aching eyes, could be classic signs of eye strain and they’re more common than ever in our screen-heavy world.

If you are suffering from frequent headaches, it could be a sign that your eyes are working harder than they should be to compensate for an uncorrected vision problem. This could be something as straightforward as needing a new prescription for your glasses or contact lenses.

Don’t dismiss persistent headaches as just tiredness or stress – they could be your body trying to tell you something.

How to track changes at home

Keeping a simple record of any symptoms you notice can be incredibly useful when you visit your optician. You don’t need anything elaborate – a few notes on your phone will do. Try logging:

• When symptoms occur – morning, evening, after screen use, in bright light?
• Which eye is affected – both, or just one?
• How often – is it an occasional occurrence or happening daily?
• What makes it better or worse – rest, lighting, distance?

This kind of information helps your optician build a much clearer picture of what might be going on and ensures you get the most from your appointment. It’s also a good idea to cover each eye in turn from time to time and check whether your vision seems equal in both – any noticeable difference is worth reporting.

When to book an eye test

Regular eye tests are about far more than updating your prescription. A thorough eye examination can detect early signs of serious conditions – including glaucoma, macular degeneration and diabetic retinopathy – often before you’ve noticed any symptoms at all.

As a general guide, adults should have an eye test at least every two years. However, you should book an appointment sooner if you notice any of the following:

• Sudden or significant changes to your vision
• New floaters, flashes of light, or a shadow in your field of vision
• Eye pain or persistent redness
• Double vision

Early intervention really can make a difference. Leaving changes unchecked, however, can mean that treatment options become more limited over time.
