Asthenopia

Asthenopia, also known as eye strain, is a common condition characterized by fatigue, discomfort, or pain in the eyes.

Causes

• Prolonged use of digital devices such as computers, smartphones, and televisions
• Reading or other visually demanding tasks for extended periods
• Incorrectly prescribed glasses or contact lenses
• Underlying eye conditions such as hyperopia (farsightedness), myopia (nearsightedness), or presbyopia
• Poor lighting or glare
• Allergies or dry eyes

Symptoms

• Dry, irritated, or itchy eyes
• Blurred vision or double vision
• Headaches or facial pain
• Sensitivity to light
• Difficulty focusing or concentrating
• Burning or stinging sensation in the eyes

Risk Factors

• Age: Asthenopia can affect anyone, but it is more common among people who spend a lot of time using digital devices, such as office workers and students
• Occupation: People who work on computers or perform other visually demanding tasks are at higher risk
• Pre-existing eye conditions: Underlying eye conditions can increase the risk of developing asthenopia

Treatment and Prevention

• Follow the 20-20-20 rule: Every 20 minutes, look away from your screen and focus on something 20 feet away for 20 seconds
• Adjust the display settings of digital devices to reduce glare and improve visibility
• Use good lighting and minimize reflections
• Take regular breaks to rest your eyes
• Get regular eye exams to ensure that any underlying eye conditions are properly diagnosed and treated
• Consider using artificial tears or other eye drops to help lubricate dry eyes

Complications

If left untreated, asthenopia can lead to more severe eye problems, such as chronic dry eye syndrome or even long-term vision damage. However, with proper treatment and prevention, most cases of asthenopia can be effectively managed.
