Everything You Need to Know About Myopia

May 13, 2020

Not sure exactly what myopia is? In recognition of it being Myopia Awareness Week, our Calgary optometrist has put together everything you need to know about what is often referred to as nearsightedness.


Myopia, also known as nearsightedness, is a common vision condition that affects a person’s ability to see objects in the distance clearly. People with myopia have no problem seeing things close to them, but objects far away are often blurry or tough to see. With it being Myopia Awareness Week, our Calgary optometrist has put together an article that covers everything you need to know about this common vision condition.

What is myopia?

This common vision condition, which is often referred to as nearsightedness, is the most prevalent cause of impaired vision in the world among those who are 40 years or younger. Myopia happens when the shape of someone’s eye results in light bending, or refracting, incorrectly, which leads to focusing on objects in front of your retina as opposed to on your retina. Myopia can also be caused by the lens of your eye being curved too much in relation to the length of your eyeball. Sometimes myopia is caused by these two causes working in combination with one another.

 
A simple eye exam can diagnose myopia. If you feel like you may be suffering from this common vision condition, contact My Optometrist Calgary today to book a comprehensive eye exam and we can confirm whether or not this is the issue you’re experiencing.

Symptoms of myopia

Myopia usually first shows up during childhood. Some symptoms of myopia include:

  • Blurred vision when looking at objects far away
  • Having to squint to see objects clearly
  • Headaches due to eye strain
  • Difficulty seeing road signs

 
Myopia commonly runs in families, making it a hereditary condition. If one of your parents suffers from nearsightedness, you’re more likely to develop this common vision condition. If both your parents suffer from myopia, your risk increases even more.

 

How is myopia treated?

There are a number of different ways that nearsightedness can be treated. The most common ways myopia is corrected are:

  • Eyeglasses
  • Contact lenses
  • Vision surgery (e.g. LASIK)


Given the severity of your myopia, you may need to wear your corrective eyeglasses or contact lenses at all times, or only when clear vision at a distance is required. Some examples of the latter include driving, clearly seeing a whiteboard or chalkboard while at school, or when watching TV or a movie.

Are there any other causes of myopia?

Some other causes of myopia have been linked to environmental factors or health problems such as:

  • Distance vision that’s blurry only at night. Known as night myopia, the low lighting makes it challenging for eyes to focus normally. Someone suffering from this condition may need glasses in order to drive their vehicle during evening hours.
  • Those who are constantly engaged in near-vision work may suffer from “fake” myopia due to overusing the focusing apparatus of their eyes and experience blurred distance vision as a result. The problem usually resolves itself after the eyes have had a chance to rest, but constantly straining the eyes under these conditions could lead to decreased distance vision as time goes on.
  • People who are diabetic may experience myopia symptoms due to changes in their blood sugar levels, or the symptoms may be an early sign of cataracts developing.

 
If you find yourself potentially suffering from any of these issues, our Calgary optometrist can conduct a comprehensive eye exam to determine the cause of your vision problems.
