A number of computer and smartphone applications adjust the computer video color temperature, reducing the amount of blue light emitted by the screen, particularly at night. Dry eye is a symptom that is targeted in the therapy of CVS. The use of over-the-counter artificial-tear solutions can reduce the effects of dry eye in CVS.
The experience of eye strain when reading in dim light has given rise to the common misconception that such an activity causes permanent eye damage. [3] When concentrating on a visually intense task, such as continuously focusing on a book or computer monitor, the ciliary muscles and the extraocular muscles are strained. This causes discomfort ...

According to the American Optometric Association: "Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20-28 inches from the eyes."
Computer Eye Syndrome is an umbrella term for many problems but the causes of these problems can be easily identified. When using a computer due to the size and setup of the monitor and components it is necessary for the user to be within at least two feet of the monitor when performing any type of computational work. This presents many ...
A digital screen does not radiate harmful energy against human eyes, but staring at the screen for a long time without pauses does increase eye strain. There is no evidence to support the claim that exposure to digital screens contributes to the risk of macular degeneration. [31] [16] [32]
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
