Devices to help children with visual impairments see better, such as magnifiers, CCTV, and special software.

Children with a certain level of vision (better than 6/60) often benefit from adjusting their viewing distance and using accommodation.

Children without a lens in the eye usually need stronger magnification, such as stand magnifiers or spectacle magnifiers.

Children with these conditions benefit from closed-circuit televisions (CCTVs) and on-screen enlargement capabilities.

Almost all school-aged children with visual impairments can use distance aids.

Adjusting lifestyle and career choices may be necessary for older children and teenagers.

Visual impairment could potentially lead to reduced or no driving rights and impact career prospects.

Although not legally required, pushbikes may be a practical alternative for those with visual impairments (no driving rights) requiring consideration and safety.

Visual loss during childhood and early teens, often congenital or hereditary.

Visual impairment observed in newborns.

Newborn infants typically have hypermetropia (farsightedness) of 2-3 diopters, often with astigmatism.

Visual sharpness typically improves as the visual system matures, and refractive error reduces.

The central part of the retina, crucial for sharp vision, is not fully developed at birth and takes several months to mature.

Evaluating a newborn or young infant's vision requires patience and specialized techniques.

Nearsightedness (myopia) often develops progressively throughout childhood and adolescence.

The visual system of an infant matures gradually, impacting visual acuity and refractive error.

A rare inherited disorder where the body can't transport fats properly due to a deficiency in a specific protein.

Nyctalopia (night blindness), neuromuscular weakness, dietary fat intolerance, progressive spinocerebellar ataxia, and retinopathy.

High doses of oral vitamin E, a low-fat diet, and supplements of other fat-soluble vitamins.

These are conditions affecting the retina, often causing mild vision problems in early childhood that worsen later.

Because early interventions can help them adapt, use low vision aids, and achieve as much independence as possible.

They provide tools to improve visual function, making it easier to learn, participate in activities, and live a more fulfilling life.

They assess vision, prescribe low vision aids, and guide families on managing the condition and accessing educational support.

It can lead to relatively normal distance vision through contact or intraocular lenses.
