Dry eyes, otherwise called dry eye disorder or keratoconjunctivitis sicca, is a condition described by deficient or low quality tears to grease up and feed the eyes. Tears are essential for maintaining the health and comfort of the eyes, providing a smooth surface for clear vision and protecting the eyes from irritants and infections.
Computer Vision Syndrome (CVS)?
Computer Vision Syndrome (CVS), also known as digital eye strain, is a condition caused by prolonged use of digital screens such as computers, smartphones, tablets, and other electronic devices. It is characterized by a range of symptoms that result from staring at digital screens for extended periods. The main factors contributing are:
1. Extended Screen Time: Spending long hours in front of digital screens can cause eye strain and fatigue.
2. Reduced Blink Rate: People tend to blink less frequently when using digital devices, leading to reduced moisture on the surface of the eyes.
3. Blue Light Exposure Computerized screens produce blue light, which can add to eye strain and disturb rest designs
4. Screen Glare: Glare from screens or reflections can cause discomfort and strain on the eyes.
Dry Eyes Management and Treatment :
Dry eye syndrome affects millions worldwide, leading to discomfort and blurred vision. Advanced therapies offer better solutions than traditional remedies. Here are three cutting-edge treatments:
Factors That contribute to Dry Eyes ?
When the tear production or composition is disrupted, it can lead to dry eyes. Several factors can contribute to this condition, including:
Aging : Tear production tends to decrease with age, making older adults more prone to dry eyes.
Environmental factors : Dry or windy climates, air conditioning, and exposure to smoke or dry air can increase the evaporation of tears.
Medical conditions : Certain medical conditions like autoimmune diseases (e.g., Sjogren's syndrome), diabetes, thyroid disorders, and rheumatoid arthritis can cause dry eyes.
Medications : Some medications, such as antihistamines, decongestants, antidepressants, and certain blood pressure medications, can reduce tear production.
Prolonged screen time : Staring at screens for extended periods can lead to reduced blinking and increased tear evaporation, contributing to dry eyes.
Contact lens wear : Improper or excessive use of contact lenses can lead to dryness and discomfort.
Symptoms of Dry Eyes ?
Dryness or gritty sensation in the eyes
Redness and irritation
Itching or burning sensation
Excessive tearing (as a reflex response to dryness)
Sensitivity to light
Eye fatigue or discomfort, particularly after long periods of reading, driving, or computer use
Management and treatment of dry eyes often involve addressing the underlying cause and relieving symptoms. This may include the use of artificial tears or lubricating eye drops to supplement natural tear production. Lifestyle modifications, such as taking regular breaks during screen time, using humidifiers, wearing sunglasses, and avoiding exposure to dry or dusty environments, can also help alleviate symptoms. In more severe cases, prescription medications or procedures to block tear ducts and conserve tears may be recommended.
It's important to consult with an eye care professional, such as an optometrist or ophthalmologist, if you experience persistent or severe dry eye symptoms for proper diagnosis and appropriate treatment options.
