The watery eye
The eye is covered with a mucous membrane, known as the conjunctiva . It protects the eye and keeps it moist by producing tears regularly. Over hydration happens when the eyes produce more tears than normal. This can be a sign of an infection (for example, dry eye, blocked lacrimal pathways, dysregulation of the lacrimal glands …) when it is not caused by an emotion.
If your eye is tearful and you feel a discomfort or a sensation of infection, it is recommended that you visit your optometrist. The causes of an overhydrated eye can vary from person to person and each case might require a different solution. It’s good to know that this type of condition is not dangerous, but can be painful.
Red Eyes
Conjunctivitis, also referred to as pink or red eye, can make the eyes itchy, oozy and crusty. It is fairly easy to manage or treat.
Conjunctivitis can affect one or both eyes. It comes in different forms:
- Infective conjunctivitis – bacterial or viral infections, such as the common cold, can lead to this highly-contagious form of the disease. Infected contact lenses or contaminated eye make-up may also be responsible.
- Allergic conjunctivitis – allergic reactions to pollen, animal fur or dust mites can inflame the conjunctiva.
- Irritant conjunctivitis – substances such as chlorinated water, shampoo or air pollution can irritate the eye. A loose eyelash can also lead to this form of conjunctivitis.
How to spot it ?
The eyes will be red and inflamed, and there can be a thick yellow discharge, which crusts over the eyelashes, especially after sleep. Itchy or watery eyes are also common symptoms. Some people may experience a burning or gritty sensation in the eyes, or swollen eyelids. Infective conjunctivitis can be accompanied by cold-like symptoms, such as a fever or a sore throat. Allergic conjunctivitis often occurs in connection with hay fever symptoms, such as sneezing and a runny, itchy nose.
Our Advice
- Antibiotic eye drops or ointment can be prescribed for infective conjunctivitis
- Avoid rubbing your eyes
- Apply cold compresses for a few minutes on your eyelids, 3 to 4 times a day
- Antihistamines can be prescribed for allergic conjunctivitis
- Always pay attention to the expiry dates of your cosmetics and get rid of those that have passed the deadline
Itching of the eye
Eye itching is usually caused by allergies, but conjunctivitis, fatigue or eye strain can also be the cause. If you have a doubt on having an infection, please visit your optometrist immediately.
Distinguishing the infections of the eyes:
An itchy eye is not always due to an infection or an allergy. It can also be caused by:
- An insect bite (e.g mosquitoes or spiders) on the edges of the eye is often painful and itchy. They usually appear several hours after the incident. Avoid scratching at the risk of causing an infection. Apply an ice compress on the affected area to relieve the itching.
- If you see a small lump at the level of the lashes or in the middle of the eyelid and it is accompanied by a sensation of heaviness, then it is most likely a sty. This is not serious, however it is advisable to consult your optometrist.
Solutions for the itchy eyes:
- Avoid rubbing your eyes so as not to irritate them
- Use compresses with distilled or boiled water
- Humidify your eye with artificial tears
- Visit your optometrist if itchiness persists
