Frequently Asked Questions

How is colour blindness diagnosed?

Colour blindness or colour deficiency is typically diagnosed through specialized tests conducted by eye care professionals. These tests assess an individual’s ability to distinguish colours and determine the specific type and severity of colour vision deficiency present. One commonly used test is the Ishihara colour vision test, which uses a series of plates with coloured dots or numbers that individuals with normal colour vision can distinguish but may be challenging for those with colour blindness. A comprehensive eye examination can help determine the extent of colour vision deficiency and its impact on daily life.

Colourblind individuals should generally follow the same recommended schedule for regular eye checkups as individuals with normal colour vision. In Canada, the recommended frequency of eye checkups for individuals with colour vision deficiency (colorblindness) is generally the same as for the general population.

For individuals with colour vision deficiency, regular eye checkups are essential to monitoring overall eye health, identifying any potential changes or new issues, and ensuring that they are receiving appropriate care. These checkups can also provide an opportunity to discuss any challenges or concerns related to their colourblindness.

It’s advisable for colourblind individuals to discuss their specific needs and circumstances with an eye care professional. The eye care professional can then provide personalized recommendations for the frequency of eye checkups.

The primary symptom of myopia is difficulty seeing objects at a distance, such as road signs or chalkboards. Other symptoms may include eyestrain, headaches, squinting, and needing to sit closer to screens or books to see clearly.

Myopia, commonly known as nearsightedness, is an eye condition where distant objects appear blurry, while close objects can be seen clearly. It occurs when the eyeball is too long or the cornea’s curvature is too steep, causing light to focus in front of the retina instead of directly on it.

The corneal curve is measured using a technique called corneal topography. This non-invasive procedure creates a detailed map of the corneal surface, showing its curvature and any irregularities. During the test, you may be asked to focus on a target, and a specialized instrument captures images of the cornea’s shape. The data obtained from corneal topography aids in assessing tear film stability, identifying areas of potential dryness, and assisting in the diagnosis and management of dry eye.

Yes, the corneal curve can provide insights into the severity of dry eye. An uneven corneal surface can disrupt the tear film, leading to dryness and discomfort. Specialized tests, such as corneal topography, evaluate the curvature of the cornea and its impact on tear distribution. Changes in the corneal curve, along with other clinical assessments, help eye care professionals determine the severity of dry eye and tailor appropriate treatment strategies.

The curve on the front of the eye, known as the cornea, plays a crucial role in dry eye detection. Changes in the corneal surface can affect tear distribution and stability, leading to dry eye symptoms. Optometrists and ophthalmologists use advanced imaging techniques to analyze the corneal curvature and its changes over time. This helps detect dry eye by identifying irregularities that can contribute to tear film instability and ocular discomfort.

The MYAH is a versatile tool that does many things. It measures the length of your eye, checks the shape of your cornea, looks at how your pupil responds to light, and analyzes how light behaves on the front surface of your eye. It can image the meibomian gland structure and tear film height. It’s also helpful for finding the right kind of contact lenses. The MYAH helps keep track of how your eye changes over time, measures your eye’s focusing power, and shows any differences in the shape of your cornea between visits. It can also show how light might be causing some blurriness. So, it’s like a really useful tool for understanding your eye health and helping you get the best lenses if you need them.
