What role does diet play in managing dry eyes?
A balanced diet can help manage dry eyes. Including foods rich in omega-3 fatty acids such as oily fish, flaxseed and walnuts can improve tear quality. Drinking enough water is also crucial to keeping eyes properly hydrated.
What are the long-term effects of untreated dry eye?
Untreated dry eye can lead to serious complications, including damage to the surface of the eye. These lesions can manifest as superficial punctate keratitis, corneal ulcers and corneal scarring, which can impair vision. Persistent dryness can also lead to chronic inflammation, increasing the risk of eye infections.
What's the difference between dry eye and other eye conditions?
Dry eye is distinguished from other eye conditions by its origin in the production and quality of tears. Unlike conditions such as conjunctivitis or glaucoma, dry eye is specifically due to an imbalance in the tear film. Symptoms may overlap, but accurate diagnosis by a healthcare professional is essential for appropriate management.
Can contact lenses aggravate dry eyes?
Yes, prolonged contact lens wear can exacerbate dry eyes. Lenses can absorb moisture from the eyes, reducing natural lubrication. Dry eye sufferers are advised to use lenses specially designed for better hydration, or to limit the amount of time they wear their lenses.
Do hormonal changes affect dry eyes?
Hormonal changes play a significant role in the development of dry eye, particularly in women. Hormonal fluctuations associated with menopause, pregnancy and the use of oral contraceptives can reduce tear production and alter tear composition. Menopausal women are particularly susceptible to severe dry eye.
What is the link between the work environment and dry eyes?
Thework environment can have a significant impact on dry eyes. Air-conditioned offices, spaces with low humidity and prolonged exposure to computer screens all increase the risk of developing dry eye symptoms. We recommend taking regular breaks, using humidifiers and adjusting screen position to minimize eye strain.
