In many cases, frequent computer users develop computer vision syndrome, which is a degenerative eye problem which can result in severely reduced eyesight , blurred vision, overall eye tiredness and even glaucoma. Computer Eye Syndrome is an umbrella term for many problems but the causes of these problems can be easily identified.
Computer vision syndrome (CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye's muscles being unable to recover from the constant tension required to maintain focus on a close object.
Along with developing esophageal voice, using a speech synthesizer, or undergoing a surgical procedure, the electrolarynx serves as a mode of speech recovery for laryngectomy patients. [ 2 ] [ 3 ] The Voice Quality Symbol for electrolaryngeal phonation in speech is И, approximating the symbol for electricity.
The loss of voice and of normal and efficient verbal communication is a negative consequence associated with this type of surgery and can have significant impacts on the quality of life of these individuals. [20] [21] Voice rehabilitation is an important component of the recovery process following the surgery. Technological and scientific ...
The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
Astigmatism, a disorder that affects how the eyes focus light, can be exacerbated at night. Blurry vision and headaches are symptoms of astigmatism. Why astigmatism causes blurry vision ...
When the cornea dries out it may stick to the eyelid and cause an abrasion when the eye reopens. [11] Exposure keratitis. Chemical injury can occur if cleaning solutions such as povidone-iodine (Betadine), chlorhexidine or alcohol are inadvertently spilt into the eye, for example when the face, neck or shoulder is being prepped for surgery.

This dilation may pose a problem since a larger pupil is less efficient at focusing light (see pupil, aperture, and optical aberration for more.) Patients who have accommodative spasm may benefit from being given glasses or contacts that account for the problem or by using vision therapy techniques to regain control of the accommodative system.
