Eyestrain and Astigmatism
DEFINITION
Eyestrain occurs when your eyes get tired from intense use, such as driving a car for extended periods, reading or working at a computer.
Although eyestrain can be annoying, it usually isn't serious and goes away once you rest your eyes. In some cases, signs and symptoms of eyestrain can indicate an underlying eye condition that needs treatment. Although you may not be able to change the nature of your job or all the factors that can cause eyestrain, you can take steps to reduce eyestrain.
SYMPTOMS
Eyestrain signs and symptoms include:
Sore, tired, burning or itching eyes
Watery eyes
Dry eyes
Blurred or double vision
Headache
Sore neck
Sore back
Shoulder pain
Increased sensitivity to light
Difficulty focusing
Computer use or the use of other digital electronic devices can cause many of these symptoms.
If home treatments don't work to relieve your eyestrain symptoms, seek help as soon as possible if you have ongoing symptoms that may include:
Eye discomfort
A noticeable change in vision
Double vision
Headache
CAUSES
Common causes of eyestrain include:
Extended use of a computer or digital electronic devices
Reading for extended periods
Other activities involving extended periods of intense focus and concentration, such as driving a vehicle
Exposure to bright light or glare
Straining to see in very dim light
Using a computer for long periods is one of the most common causes of eyestrain. This type of eyestrain is called computer vision syndrome. In some cases, an underlying eye problem such as eye muscle imbalance or uncorrected vision can cause or worsen computer eyestrain.
RISK FACTORS
Risk factors for eyestrain include:
Activities that require intensive or extended use of your eyes for tasks such as using a computer, studying printed materials or driving
Underlying eye problems such as an eye muscle imbalance or uncorrected vision (refractive error)
Stress or fatigue
