  2. Computer vision syndrome - Wikipedia

    en.wikipedia.org/wiki/Computer_vision_syndrome

    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.

  3. Presbyopia - Wikipedia

    en.wikipedia.org/wiki/Presbyopia

    There is some confusion over how the focusing mechanism of the eye works. [clarification needed] In the 1977 book, Eye and Brain, [13] for example, the lens is said to be suspended by a membrane, the 'zonula', which holds it under tension. The tension is released, by contraction of the ciliary muscle, to allow the lens to become more round, for ...

  4. Refractive error - Wikipedia

    en.wikipedia.org/wiki/Refractive_error

    When an eye focuses light correctly on to the retina when viewing distant objects, this is called emmetropia or being emmetropic. This means that the refractive power of the eye matches what is needed to focus parallel rays of light onto the retina. A distant object is defined as an object located beyond 6 meters (20 feet) from the eye ...

  5. Blurred vision - Wikipedia

    en.wikipedia.org/wiki/Blurred_vision

    Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2] Glaucoma: Increased intraocular pressure (pressure in the eye) cause progressive optic neuropathy that leads to optic nerve damage, visual field defects and blindness. [6]

  6. Eye strain - Wikipedia

    en.wikipedia.org/wiki/Eye_strain

    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 ...

  7. Computer-induced medical problems - Wikipedia

    en.wikipedia.org/wiki/Computer-induced_medical...

    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.

  8. Tunnel vision - Wikipedia

    en.wikipedia.org/wiki/Tunnel_vision

    Given reading is a crucial skill to understand one's surrounding, e.g., reading directions in the airport, about 60% of patients mentioned reading difficulty as the reason for their referral to the low vision care, and reading problem is a major source of anxiety for Glaucoma patients with slower reading speed, more errors, and slower ...

  9. Vergence-accommodation conflict - Wikipedia

    en.wikipedia.org/wiki/Vergence-accommodation...

    Both of these mechanisms are crucial in stereoscopic vision. Vergence or independent inward/outward rotation of eyes is engaged to fixate on objects and perceive them as single. Incorrect vergence response can cause double vision. Accommodation is the eye’s focusing mechanism and it is engaged to produce a sharp image on a retina.
