Can a colour blind person see any colours?
Yes, many people experiencing colour blindness can see some colours, but not all. This is because there are different types of colour blindness, and each type affects a person’s ability to see different colours. For example, red-green colour blindness affects the ability to see red and green colours, while blue-yellow colour blindness affects the ability to see blue and yellow colours. Some people with complete colour blindness, however, cannot see any colours at all.
Symptoms of colour blindness
Colour blindness, also known as colour vision deficiency, is a condition in which a person has difficulty distinguishing between certain colours. It’s usually a genetic condition caused by abnormalities in the colour-detecting cells (cones) of the retina. The most common form of colour blindness is red-green colour blindness. Here are the typical symptoms of colour blindness:
- Difficulty distinguishing between red and green: People with red-green colour blindness have trouble telling the difference between shades of red and green. This can include confusing red and green traffic lights or difficulty identifying ripe fruits.
- Seeing colours as dull or faded: Some individuals with colour blindness might perceive certain colours as less vibrant or appear washed out.
- Confusing certain colour pairs: Apart from red and green, people with colour blindness may have trouble differentiating between other colour pairs, such as blue and purple, or pink and gray.
- Inability to identify specific colours: In severe cases of colour blindness, individuals may not be able to identify specific colours at all.
- Difficulty with colour-coded information: Color-blind individuals may struggle to interpret color-coded information, such as maps, charts, or graphs that rely heavily on color differentiation.
- Challenges in low-light conditions: Color vision deficiency can be more pronounced in dimly lit environments or under certain types of lighting.
It’s important to note that color blindness is a spectrum, and its severity can vary from mild to severe. Additionally, there are different types of color blindness, each affecting the perception of colors in a specific way.

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.
