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 ...
The American Tinnitus Association estimates there are roughly 200 health disorders that can generate tinnitus symptoms. Not exactly a small number. Not exactly a small number. Photo: Getty
More than 260 medications have been reported to cause tinnitus as a side effect. [41] Tinnitus can also occur from the discontinuation of therapeutic doses of benzodiazepines. It can sometimes be a protracted symptom of benzodiazepine withdrawal and may persist for many months. [42] [43] Medications such as bupropion may also cause tinnitus. [44]
That suggests patients with tinnitus could have damaged auditory nerves that no longer send signals to their brains, potentially resulting in brain activity that causes patients to hear sounds of ...
Though the pathophysiology of tinnitus is not known, noise exposure can be a contributing factor, therefore tinnitus can be associated with hearing loss, generated by the cochlea and central nervous system (CNS). High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19] Noise ...
Too much video game playing may cause vision problems. [11] Extensive viewing of the screen can cause eye strain, as the cornea, pupil, and iris are not intended for mass viewing sessions of electronic devices. Using video games for too long may also cause headaches, dizziness, and chances of vomiting from focusing on a screen.
Migraines and tinnitus are common comorbidities that are both associated with a more severe presentation of the syndrome. [13] The cause of the syndrome is unclear. [3] The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left anterior lobe of the cerebellum.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
