Frequently Asked Questions

Can girls be colour blind?

Yes, girls can be colour blind. Colour blindness is a condition that affects a person’s ability to see colours accurately. It can affect both boys and girls but is much more common in boys than in girls. The genes for colour detection are located on the X sex-linked chromosome. A male has an X from the mother and a Y from the father. A female has an X from the father and an X from the mother. The gene for colour deficiency is recessive, meaning that if there is one good chromosome and one deficient, the good one will override and provide normal function. Boys have only one X chromosome from the mother, as the Y chromosome would come from the father. So colour blindness in males always comes from the mother’s side of the family. Girls have an X chromosome from both the father and mother, so they have a chance to have a normal one from each side, so it is much more rare to have a girl with colour deficiency. If there is a girl with colour deficiency (both X chromosomes are deficient), 100% of her male children would be colour deficient.

Colour blindness is more common in men than women because the genes responsible for colour vision are located on the X chromosome. Since women have two X chromosomes and men have only one X chromosome and one Y chromosome, the genetic mutation that causes colour blindness is more likely to affect men. In women, a healthy X chromosome can often compensate for the mutated gene on the other chromosome, whereas men do not have this same genetic backup. As a result, men are more likely to inherit and express the genetic mutation that causes colour blindness. While colour blindness affects a relatively small percentage of the population, it can still have a significant impact on an individual’s quality of life and ability to perform specific tasks, such as distinguishing between traffic lights or reading maps.

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.
