Frequently Asked Questions

Can colour blind people drive?

Yes, colour-blind people can drive. Colour blindness is a condition that affects a person’s ability to see colours accurately. It does not affect a person’s ability to see in the dark or to drive.

Colour blindness, also known as colour vision deficiency, is a condition that affects a person’s ability to perceive certain colours or distinguish between them. It is typically caused by abnormalities or deficiencies in the colour-sensing pigments in the cone cells of the retina.

The most common types of colour blindness are:

  1. Red-green colour blindness: This is the most common form and is more prevalent in males. People with red-green colour blindness have difficulty distinguishing between shades of red and green. They may perceive these colours as brownish, yellowish, or gray.
  2. Blue-yellow color blindness: This type is rarer and affects the ability to differentiate between shades of blue and green, as well as between shades of yellow and violet. Blue may appear green, and yellow may appear violet or gray.
  3. Total colour blindness: This is a rare form of colour blindness in which a person sees the world in shades of gray. It is caused by the absence or malfunctioning of all three types of cone cells.


Colour blindness can have various causes, including:

  • Genetics: The most common cause of colour blindness is an inherited genetic mutation that affects the development or functioning of the cone cells in the retina. These mutations are carried on the X chromosome, which is why red-green colour blindness is more common in males.
  • Acquired conditions: Some medical conditions or eye diseases, such as age-related macular degeneration, cataracts, or glaucoma, can cause colour vision deficiencies.
  • Medications and chemicals: Certain medications, such as some antibiotics and antipsychotics, can affect colour vision. Exposure to certain chemicals, such as fertilizers or industrial toxins, can also cause colour vision problems.
  • Aging: As people age, there may be a natural decline in colour vision due to changes in the eye’s structure and function.


The impact of colour blindness on individuals can vary depending on the severity and type of deficiency. It may affect daily tasks that rely on colour discrimination, such as identifying ripe fruit, matching clothing, or reading colour-coded information. However, with adaptation and the use of alternative cues (e.g., brightness or position), many individuals with colour vision deficiencies can effectively navigate their environment.

It’s important to note that colour blindness does not typically cause significant health problems or vision loss. However, it can affect certain professions or activities that require accurate colour perception, such as being a pilot, electrician, or graphic designer.

Seniors can maintain good eye health by eating a healthy diet, wearing sunglasses to protect their eyes from UV rays, and avoiding smoking. They should also be vigilant about any changes in their vision and seek medical attention promptly if they experience any concerns.

If an eye condition is detected, the optometrist will discuss and educate the patient in a way that is easy to understand. If the condition requires treatment, they will discuss risks and benefits, and initiate treatment. If surgical intervention is required they will refer the senior to a specialist for further evaluation and treatment.

Seniors should make a list of any concerns or symptoms they are experiencing and bring it to their appointment. They should also bring any eyewear they are using or would like to ask questions about, as well as a list of any current medications.

An eye exam for seniors typically takes about 30 to 60 minutes, depending on the complexity of the exam.

Some optometrists offer tele-optometry services, which allow seniors to have an eye exam from the comfort of their own home using video conferencing technology.

Alberta Health Care covers eye exams for seniors aged 65 and older once every 12 months.
