Key Takeaways

  • Your vision can shift with age, screen habits, and family history.
  • Health conditions like diabetes and high blood pressure can affect your sight.
  • Cataracts, glaucoma, and macular degeneration often start with small changes.
  • Blurry vision even with glasses can mean your prescription needs updating.
  • Children’s eyes change fast, so early checkups and myopia control matter.
  • Regular eye exams help catch problems early.

You reach for your phone and the words look a little fuzzy. Or you squint at road signs you used to read with ease. These small changes can feel worrying, but they’re common, and Port Moody Eye Care Centre can help you find out why.

Your eyesight can get worse for many reasons, including natural age changes, long hours on screens, family history, health conditions, and eye diseases that develop slowly over time.

How Age Affects Your Focus

After 40, many people notice close-up tasks get harder. This is called presbyopia, a normal change where the lens inside your eye becomes less flexible.

You might hold your menu or phone at arm’s length to read it clearly. That’s a common sign your eyes need a little help focusing up close.

Screen Time and Digital Eye Strain

When you stare at a screen, you blink less. That can leave your eyes feeling dry, watery, or tired by the end of the day.

Long screen sessions can also bring on headaches, a sore neck, and blurry vision. A simple habit can help. Every 20 minutes, look at something 20 feet away for 20 seconds. This is the 20-20-20 rule, and it gives your eyes a short break.

Health Conditions and Habits That Can Affect Your Sight

Your eyes are connected to the rest of your body. Diabetes and high blood pressure can both change the tiny blood vessels in your eyes, which may affect how well you see.

Some medications can lead to blur or dryness too. Smoking, a poor diet, and too much sun can also add up over the years.

Everyday Choices for Healthier Eyes

Small daily habits can support your vision for the long run. Try to:

  • Eat a balanced diet with plenty of fruits and vegetables.
  • Wear sunglasses with UV protection when you’re outside.
  • Get enough sleep and cut back on smoking.

Eye Conditions to Watch For

Some vision changes come from eye conditions that develop quietly. Cataracts cloud the lens of your eye, so your vision may look hazy or dim.

Glaucoma affects the optic nerve, the cable that carries images from your eye to your brain. Macular degeneration touches your central vision, making it harder to see straight ahead.

Signs Worth a Closer Look

A few symptoms are worth a call to your optometrist, including:

  • Blurry vision or straight lines that look wavy.
  • Trouble seeing at night.
  • Frequent headaches or sensitivity to glare.

Why Your Vision May Worsen Even with Glasses

You wear your glasses every day, yet things still look off. Often, your prescription is simply out of date and needs a small update.

Your eyes keep changing with age, even when you wear corrective lenses. Sometimes a health issue is at play, which is why a full exam matters more than a quick lens swap.

Vision Changes in Children

Kids’ eyes grow quickly, and many children develop myopia, or nearsightedness, where distant objects look blurry. Myopia control options can help slow how fast it progresses.

Our team offers on-site axial length measurement, which tracks the length of your child’s eye to follow changes closely over time. Early checkups give growing eyes the attention they need.

How Regular Eye Exams Help You See Clearly

Regular exams help our team spot changes early, often before you notice them yourself. A full eye exam looks beyond your prescription to assess the overall health of your eyes and identify potential problems that could affect your vision.

At Port Moody Eye Care Centre, every full eye exam includes screening for dry eye, which can cause fluctuating or blurry vision, irritation, burning, or tired eyes. When risk factors are identified, we can also perform additional glaucoma screening to check for signs of this often-silent eye disease.

Our comprehensive eye exams also include in-depth retinal assessments. Depending on your examination, retinal photos, OCT imaging, and dilated fundus examinations (DFE) allow our team to take a closer look at the structures at the back of your eye. These assessments can help identify changes that may not be noticeable from your vision symptoms alone.

An up-to-date prescription makes daily tasks easier, from reading recipes to driving at dusk, but clear vision is only one part of a healthy eye exam. Looking closely at the health of your eyes can help us understand why your vision may be changing and determine whether additional monitoring or treatment is needed.

What to Expect at Your Appointment

During your visit, our team will review your family and health history and assess both your vision and overall eye health. We use advanced diagnostic technology to get a more detailed picture of what’s happening inside your eyes.

Your full exam includes dry eye screening, and if glaucoma risk factors are identified, additional glaucoma screening may be recommended. We also perform in-depth retinal assessments using tools such as retinal photography, OCT imaging, and dilated fundus examination (DFE) to evaluate the health of the structures at the back of your eyes.

If dry eye, myopia, or another concern is identified, we can talk through options and next steps that fit your needs and day-to-day life.
