Preliminary laboratory investigations using retinoscopy of 240 dogs [4] found myopic problems with varying degrees of refraction errors depending on the breed. In cases involving German Shepherds, Rottweilers and Miniature horses, the refraction errors were indicative of myopia. Nuclear sclerosis of the crystalline lens was noticed in older ...
Many people with Stickler syndrome are very nearsighted (described as having high myopia) because of the shape of the eye. People with eye involvement are prone to increased pressure within the eye ( ocular hypertension ) which could lead to glaucoma and tearing or detachment of the light-sensitive retina of the eye ( retinal detachment ).
If the brain never learns to see objects in detail, then there is a high chance of one eye becoming dominant. The result is that the brain will block the impulses of the non-dominant eye. In contrast, the child with myopia can see objects close to the eye in detail and does learn at an early age to see objects in detail. [medical citation needed]
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

As opposed to the more commonly performed cataract treatment, the idea of removing the lens exclusively for refractive purposes first emerged in the 18th century. [12] French ophthalmologist Abbé Desmonceaux may be the first to suggest such an operation in 1776 for a patient with high myopia. [ 12 ]
Additionally, focusing on near objects for long periods of time - such as when reading, looking at close screens, or writing - has been associated with myopia. [ 25 ] [ 26 ] Socioeconomic status and higher levels of education have also been reported to be a risk factor for myopia. [ 27 ]
The prevalence of myopia has been reported as high as 70–90% in some Asian countries, 30–40% in Europe and the United States, and 10–20% in Africa. [130] Myopia is about twice as common in Jewish people than in people of non-Jewish ethnicity. [132] Myopia is less common in African people and associated diaspora. [129]
A phakic IOL. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery.
