  2. 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 ...

  3. Pseudoexfoliation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pseudoexfoliation_syndrome

    The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision [3] (pseudoexfoliation glaucoma, exfoliation glaucoma). As worldwide populations become older because of shifts in demography, PEX may become a matter of greater ...

  4. Ocular hypertension - Wikipedia

    en.wikipedia.org/wiki/Ocular_hypertension

    Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]

  5. Vision disorder - Wikipedia

    Such movements can cause irritation and fatigue to the eyes. [9] Glaucoma: occurs when the optic nerve is damaged and can result in irreversible vision loss, with the potential to pass undetected until this damage occurs. It is caused when aqueous humour fails to adequately drain from the eye, resulting in pressure build-up. [10]

    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]
