A foreign body in the eye
Eyelashes, dust or sand can cause eye irritation as well as cause dry eyes. In any case, we advise you not to rub or put your fingers into your eyes. It’s best to rinse your eyes with spring water. In case of persistent pain and signs of infection, visit your optometrist quickly.
Allergies
Most often, itchy eyes are caused by seasonal allergies, like those involving pollen. These allergies are the cause of allergic conjunctivitis. Although they occur more frequently in the spring and summer, they can also occur throughout the year. In addition to pollen, other allergens can cause allergic reactions, such as animal hair or dust. Indoor dust can sometimes contain fungus spores, mould and animal dandruff, potential sources of irritation. Allergies can also cause other unpleasant symptoms, for example, the sensation of twitchy eyes.
Eye infections
Several microorganisms can infect your eyes, such as bacteria, fungi or viruses. Upon contact with these organisms, your eyes may sting or become inflamed. Eye infections can affect the cornea, the whites of the eyes, or even the eyelid.
Contact lenses
Wearing contact lenses can cause discomfort for some people, including red eyes, tears or even irritation. Discover our essential tips to ensure good eye health when wearing contact lenses.
Red eyes
Having red eyes means irritated, bloodshot eyes. What can cause red eyes?
- Infections
- Allergies
- Wearing contact lenses for too long
- Eye fatigue
- Swimming pool chemicals
- Too much screen time
- Blepharitis
- A stye
- A subconjunctival hemorrhage from blood vessels under the conjunctiva
Red eyes are also associated with more serious problems such as uveitis or glaucoma. These conditions often require the intervention of a specialist doctor.
Dry eye
Blinking your eyes helps your eyelids moisten the eye surface with tears, mucin, and oil, forming the tear film. This film helps lock in moisture for proper hydration. If you do not produce enough tears or this protective film is damaged, it can cause dry eyes, irritation, or a feeling of sand in your eyes. Some people may even experience a slight burning sensation; this is called dry eye. Very often, dry eye causes eye irritation, and the two often go hand-in-hand.

However, pay attention and if you find that the discomfort persists, consult a healthcare professional.
