Signs you might need new glasses.

Many people live with vision problems far longer than they should. They put up with headaches, squinting, or blurred screens, assuming it’s normal — or a sign of tiredness. In reality, these symptoms often indicate that your glasses are no longer giving you the sharp, comfortable vision they once did.

Here are the clearest signs your eyes may be telling you it’s time for a new pair, and how to know when to book a test at Iology in Barking.

Blurred or "softened" vision

The most obvious sign is blurred vision, whether at distance, intermediate, or near. It may be constant or appear only when you’re tired.

If you’ve noticed blurriness creeping in, book an eye test today.

Headaches. Especially after screen use

Headaches at the end of the day, or after focusing, are classic signs that your prescription has changed. This is especially common in office workers and students.

Digital eye strain is increasingly common in Barking’s work-from-home community.

Difficulty focusing between near and far

If your eyes take longer to adjust when looking from a screen to a distant object, your prescription may no longer be accurate.
This affects both long-sighted and short-sighted patients.

Squinting or narrowing your eyes to see clearly

Squinting temporarily sharpens focus — but only because it reduces the amount of scattered light entering the eye.
If you catch yourself doing this often, it’s a reliable sign to update your prescription.

Tired, aching, or watery eyes

Eye strain occurs when your eyes work harder than they should. This is often due to:

• incorrect prescription strength
• lens coatings wearing out
• frames sitting incorrectly

If frames slip or sit crooked, get in touch with iology Barking.

Difficulty driving at night

Halos around lights, increased glare, slow focus recovery, or trouble seeing signs are all signs of prescription change or early eye-health concerns.

Book a check if night driving feels different or more stressful.

Holding screens or books closer than before

If you’re moving reading material closer or further away to find clarity, that’s a clear signal your prescription is no longer accurate.

This applies to adults and children.

Frequent smudging or scratching on lenses

If you constantly clean your glasses yet still struggle to see clearly, the lens coatings may be wearing out. Scratches, even fine ones, reduce contrast and increase glare.

If lenses need replacing drop in and speak to our team.

Frames that no longer fit properly

Sliding, pinching, or crooked frames can affect clarity. Even if your prescription hasn’t changed, poor alignment can cause eye strain.

Signs children may need new glasses sooner

Children often don’t recognise or report vision issues. Look for:

• sitting close to the TV
• losing their place when reading
• avoiding reading aloud
• tilting their head
• struggling with PE or coordination
