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.

Yes, there are cosmetic contact lenses available for people who wish to change or enhance the appearance of their eyes. These lenses come in various colours and designs, allowing you to alter your eye colour or create special effects. Cosmetic contact lenses are available both with and without vision correction. However, it’s crucial to obtain these lenses from a reputable source and with a prescription from an eye care professional. Wearing non-prescription cosmetic lenses without proper guidance can lead to eye discomfort, infections, or even depriving the cornea of necessary oxygen to function which can lead to serious health and vision issues.

Allergies can cause eye irritation and discomfort, making wearing contact lenses challenging for some individuals. However, certain types of contact lenses, such as daily disposables or lenses made from specific materials, might be more suitable for allergy sufferers. Consult your optometrist to discuss your allergy symptoms and determine the most appropriate contact lens options or if prescription allergy eye drops are recommended. Proper lens care, including regular cleaning and avoiding allergens that exacerbate symptoms, is essential to manage allergies while wearing contact lenses.

Contact lenses can exacerbate symptoms in individuals with dry eyes. However, some contact lens options are designed to alleviate discomfort for those with dry eyes. Specialized lenses, such as those with high moisture content or designed for extended wear, might be suitable. Your optometrist can recommend specific contact lens types or prescribe lubricating eye drops to help manage dry eye symptoms while wearing lenses. It’s essential to discuss your dry eye condition with your eye care professional before starting or continuing contact lens wear to ensure the best possible comfort and eye health.

If a contact lens feels stuck in your eye, try not to panic. Firstly, wash your hands thoroughly and use lubricating eye drops approved for contact lens wear to moisten your eye. Gently massage your upper eyelid while looking in the direction of the affected eye to help dislodge the lens. If the lens remains stuck, avoid excessive rubbing, as this can cause irritation. Try blinking or using rewetting drops to see if the lens moves. If unsuccessful, seek immediate assistance from an eye care professional to safely and effectively remove the contact lens.

While contact lenses are safe when used properly, there are risks associated with their wear. These risks include eye infections, corneal ulcers, allergic reactions, dry eyes, and discomfort. Improper hygiene, extended wear, sleeping with lenses on, and swimming or showering with lenses can increase the likelihood of these complications. It’s crucial to follow your optometrist’s guidelines, practice good hygiene, and adhere to wearing schedules to minimize the risks associated with contact lens wear. Immediate consultation with an eye care professional is necessary if you experience any discomfort, redness, or vision changes while wearing contact lenses.

It’s highly advisable to avoid wearing contact lenses while swimming or showering. Water, including tap water, pools, hot tubs, lakes, and oceans, contains microorganisms that can adhere to your lenses and cause eye infections. These microorganisms can lead to severe eye conditions, such as bacterial or fungal keratitis, which can be painful and sight-threatening. Always remove your contact lenses before any water activities to prevent potential eye infections and complications.
