What’s Normal and What’s Not?
If you’ve recently found yourself holding your phone further away to read a text message—or struggling to see small print in dim lighting—you’re not alone. Vision changes are a normal part of ageing, especially once you hit your 40s. But how do you know what’s typical and what’s a sign of something more serious?
Let’s break it down.
What’s Normal After 40?
As we age, our eyes go through natural changes. Here are some common vision shifts that are generally considered normal:
Presbyopia
Presbyopia is the most common age-related vision change. It happens when the eye’s lens becomes less flexible, making it harder to focus on things up close—like reading a book or threading a needle.
Signs of presbyopia:
- Needing to hold reading materials farther away
- Eye strain or headaches after close work
- Blurred distance vision after close work
- Trouble seeing in low light
Reduced Night Vision
Driving at night might start to feel more difficult. You may notice glare from headlights or halos around lights.
Dry Eyes
Your tear production may slow down, especially if you spend a lot of time on screens or in air-conditioned environments. This can lead to irritation, redness, or a gritty feeling.
Color Vision Changes
You might find it a bit harder to distinguish between certain shades—especially blues and greens—as your lenses begin to yellow slightly with age.
What’s Not Normal?
While many vision changes are expected, some symptoms could be signs of more serious conditions. See your optometrist if you experience:
Sudden Vision Loss or Blurriness
This could signal an eye emergency or underlying health issues like retinal detachment or stroke.
Flashes of Light or New Floaters
A few floaters are normal, but a sudden increase—especially paired with flashes—could be a warning sign of retinal issues.
Distorted or Wavy Vision
Straight lines looking bent or distorted could indicate macular degeneration—a leading cause of vision loss in adults over 50.
Double Vision
Seeing two images can be linked to serious problems like corneal damage, eye muscle issues, or even neurological concerns.
How Often Should You Get an Eye Exam After 40?
We recommend a comprehensive eye exam every 1 to 2 years once you turn 40, even if you don’t wear glasses or contacts. These checkups can detect early signs of:
- Glaucoma
- Cataracts
- Diabetic retinopathy
- Age-related macular degeneration (AMD)
- High blood pressure and diabetes (which often show signs in the eyes first)
