A broad definition of visual impairment includes a wide continuum of visual function loss. Aspects of visual function include visual acuity, which is the capacity to resolve detail, and accommodation (capacity to concentrate), field of vision (the area that may be seen), colour perception, and light sensitivity. A child with cerebral blindness can nevertheless be able to perceive motion. There are numerous sources of prevalence information, each of which has drawbacks. One of the fundamental pillars of the major worldwide prevention of blindness project, VISION 2020 the Right to Sight, is the reduction of visual impairment and blindness in children in resource-poor nations. Refraction and poor vision services aid visually impaired children, especially those with genetic or congenital ocular defects and enable vision improvement.

Visual impairment is a broad term that describes a wide continuum of loss in visual function. There are many aspects of visual function e.g., visual acuity(ability to resolve detail),accommodation (ability to focus), field of vision (area which can be seen), colour vision and adapt ability to light. A child with cerebral blindness may have intact perception of movement. Prevalence data can be obtained from a variety of different sources, each of which has limitations. Reducing visual impairment and blindness in children in resource-poor countries is one of the key components of the major global prevention of blindness initiative, VISION 2020 the Right to Sight. Visually impaired children especially with hereditary /congenital ocular anomalies benefit from refraction and low vision services which facilitate vision enhancement and inclusive education. Pediatricians have a key role in early detection and multidisciplinary management to minimise the impact of visual impairment (VI) in childhood.Visually impaired children especially with hereditary /congenital ocular anomalies benefit from refraction and low vision services which facilitate vision enhancement and inclusive Powerball® is such a market existing device that can be used for wrist rehabilitation and also as a sports aid for strengthening the wrist. The Powerball acts as an eccentric exercise tool, generating forces in different directions and thus causing stimulation of the forearm, hand, and wrist musculature. The tools used will be handheld dynamometer and pegboard test. Study will be conducted on Twenty eight patients in two Groups. .Group A will be Control Group that will be provided with conventional physiotherapy (isometric hand grip training exercises) and Group B will be Experimental Group that Conventional treatment with power ball training. Data will be analyzed using spss 22.0

Inclusion Criteria:

• Age ranging from 8 to 14 years,
• Both genders (male /female)

Exclusion Criteria:

• Serious medical conditions such as cardiac disease, diabetes, or uncontrolled seizures
• Significant shoulder, elbow, or
• wrist joint contractures preventing grip movement of the hand and fingers.

Participants will get separate tretment protocols and possible efforts will be put to mask the both groups about their treatment
