Nearsightedness (Myopia), Explained

Myopia, or nearsightedness, is a condition where nearby objects appear clearer than objects in the distance. It happens when the eye grows too long from front to back, causing light to focus in front of the retina instead of directly on it. Myopia usually develops in childhood and can progress over time. It doesn't typically cause pain, but it's important to have it properly assessed and managed by an eye care professional, since untreated vision issues can affect daily life and, in some cases, long-term eye health.

In this post, we'll cover what causes myopia, common signs to look out for, and what to expect if you or your eye doctor suspect you have it.

Nearsightedness: The Basics

Myopia often runs in families and tends to develop and progress during childhood and the teenage years, though it can also appear in adulthood. Genetics and how much time is spent on close-up activities (like screens or reading) are both thought to play a role.

Nearsightedness Symptoms

The most common sign of myopia is difficulty seeing things at a distance; road signs, whiteboards, or faces across a room can look blurry. Other signs may include:

• Eyestrain

• Headaches

• Squinting

• Fatigue after visual tasks

If you notice any of these, it's worth booking a comprehensive eye exam with an optometrist or ophthalmologist. Only a licensed eye doctor can properly diagnose myopia and determine what, if anything, you need.

Types of Myopia

Myopia generally falls into two categories:

Simple myopia is by far the most common form. It develops gradually, usually during childhood, and is caused by the eye being slightly longer than average or the cornea being more curved than average.

Degenerative (pathological) myopia is a rarer, more severe form where the eyeball continues to elongate over time, sometimes into adulthood. It's associated with a higher risk of eye health complications and requires closer, ongoing monitoring by an eye doctor.

Diagnosing Nearsightedness

Myopia is identified through a comprehensive eye exam, where an eye doctor tests visual acuity and evaluates the shape of the eye. This isn't something that can be self-diagnosed or assessed at home. If you suspect you or your child might be nearsighted, the right next step is booking an appointment with an eye care professional.

Managing Nearsightedness

There are several well-established ways eye doctors help patients manage myopia, including glasses, contact lenses, and other options depending on individual needs. Your eye doctor is best placed to recommend what's right for you based on your eyes, lifestyle, and overall health.

Why Regular Eye Exams Matter

Left unmanaged, higher levels of myopia have been associated with an increased risk of certain eye conditions later in life, including issues with the retina. This is one of the best reasons to keep up with regular eye exams. Early detection and ongoing monitoring make a real difference.

If you think you might be nearsighted, or it's just been a while since your last check-up, book a comprehensive eye exam with your optometrist. It's the best way to understand your eyes and keep your vision on track.
