| Abstract|| |
India, the largest democratic country in the world, is marching ahead strongly on the growth and developmental front and is poised to be the leader in the market economy. This role creates and increases far greater responsibilities on us in ensuring that the benefit of the developmental cycle reaches each and every citizen of this country, including the able and the disabled ones. It has been enshrined in the Constitution of India to ensure equality, freedom, justice, and dignity of all individuals and implicitly mandates an inclusive society. With increase in consideration of quality parameters in all spheres of life including availability, access, and provision of comprehensive services to the disabled, it is pertinent to have a look on the contribution of government in keeping the aspiration and commitment towards common people. The article attempts to review the concept of rehabilitation for the disabled keeping a focus on the blind person, and list out the activities, programs/schemes, institutional structure and initiatives taken by the Government of India (GOI) for the same and the incentives/benefits extended to blind persons. The article concludes by reiterating the importance of individual need assessment and mentioning new initiatives proposed on Low Vision services in the approved 11 th plan under National Programme for Control of Blindness (NPCB). The source of information has been annual reports, notification and the approved 11 th five-year plan of GOI, articles published with key words like rehabilitation, disability, assistive devices, low vision aids, and/or blind person through the mode of Internet. Annexure provides a list of selected institutions in the country offering Low Vision services compiled from various sources through personal communication and an approved list of training institutes under NPCB, GOI offering Low Vision training.

There has been an evolutionary process in changing attitudes regarding the disabled and blindness around the globe. About 1,000 years back the attitude was of disregard, rejection, isolation, and abuse, however, 100 years back the attitude changed to pity and benevolence. Currently, there is a positive attitude towards the disabled including the blind  and this becomes more important considering the fact that country incurs a huge expenditure directly in supporting and indirectly through loss of economic productivity of the disabled. This article attempts to review the concept of rehabilitation for the disabled keeping a focus on the blind, and list out the activities, programs/schemes, institutional and legal structure, and initiatives taken by the Government of India (GOI) for the same and the incentives/benefits extended to blind persons. The article concludes by reiterating the importance of need assessment and mentioning new initiatives proposed on Low Vision services in the approved 11 th five-year plan under the National Programme for Control of Blindness (NPCB). The source of information has been annual reports, notification and approved 11 th five-year plan (2007-12) of the GOI, articles published with key words like rehabilitation, disability, assistive devices, low vision aids, and/or blind person through the mode of Internet.

| Concept of disability and rehabilitation|| |
The goal of medicine is to promote, preserve, and restore health when it is impaired and to minimize suffering and distress. These goals are embodied in the word prevention. Successful prevention depends upon knowledge of causation, dynamics of transmission, identification of risk factors and risk groups, availability of prophylactic or early detection and treatment measures, an organization for applying these measure to appropriate persons or groups and continuous evaluation and development of procedures applied. For better understanding of the subject, it is necessary to have clarity of sequence of events leading to disability and handicap.
The sequence is described as follows:
Disease → Impairment ® Disability → Handicap
Disease is a condition of the body or some part or organ of the body in which its functions are disrupted or deranged.
Impairment is any loss or abnormality of psychological, physiological or anatomical structure or function.[Additional file 1]
Disability is any restriction or lack (resulting from impairment) of ability to perform an activity in the manner or within the range considered normal for a human being.
Handicap is a disadvantage for a given individual resulting from an impairment or disability that limits or prevents the fulfillment of a role that is normal (depending on age, sex, social and cultural factors) for that individual. The concept of handicap also includes the role of the society in creating barriers and limiting opportunities for people with disabilities.
| Rehabilitation|| |
Rehabilitation involves combined and coordinated use of medical, social, educational, and vocational measures for training or retraining the individual to the highest possible level of functional ability. The three main strategies for rehabilitation of disabled are institution-based, outreach, and community-based. ,
In general, rehabilitation encompasses the following: ,
- Early detection, diagnosis, and intervention
- Improve, facilitate, stimulate and/or provide services for people with disabilities, their families and attendant
- Medical rehabilitation i.e., management of curable disability and lessening the disability to the extent possible
- Social, psychological, and other types of counseling and assistance
- Training in self-care activities including social graces, etiquette, mobility, communication, and daily living skills with special provisions as needed
- Provision of technical, mobility and other devices
- Specialized education services
- Vocational rehabilitation services including vocational guidance, training, open placement, and self-employment
- Certification of degree of disability and provision of available concessions/benefits
- Community awareness, advocacy, empowerment
| Indian perspective for welfare of the disabled|| |
The Constitution of India ensures equality, freedom, justice, and dignity of all individuals and implicitly mandates an inclusive society for all including persons with disabilities (PWDs). In the recent years, there have been vast and positive changes in the perception of the society towards PWDs. It has been realized that a majority of PWDs can lead a better quality of life if they have equal opportunities and effective access to rehabilitation measures. According to the Census 2001, there are 2.19 crore PWDs in India constituting 2.13% of the total population. This includes people with visual, hearing, speech, locomotor, and mental disabilities. Out of these, 75% live in rural areas, 49% are literate, and only 34% are employed. PWDs in India are defined as people who are suffering from not less than 40% of any ability as certified by medical authority. 
Legislative, policy, and institutional framework 
The core of public health depends on law and science and it is also true that without the coercive power of the state, public health and modern society would be impossible. Law has to prohibit individuals who create situations for suffering for others. For this reason, public health must maintain the balance between individual autonomy and community protection. The public health actions are not intended to punish but to improve and monitor the health status in the community. To achieve the fundamental goals of protection, promotion and growth of individuals, groups and vulnerable population, various legislation and policies are drafted. Policy is a system that provides logical framework and rationality of decision making for the achievement of intended objectives. In short, policies set priorities and guide allocation of appropriate resources through establishment of an institutional
• GOI has enacted three legislations for PWDs viz.
- National Trust for Welfare of Persons with Autism, Cerebral Palsy, Mental Retardation and Multiple Disability Act, 1999.
- Persons with Disability (Equal Opportunities, Protection of Rights and Full Participation) Act, 1995.
- Rehabilitation Council of India Act, 1992.
• A policy, National policy for people with disability, 2004.
• Seven national levels institutes viz.
- National institute for the visually handicapped, Dehradun
- National institute for the hearing handicapped, Mumbai
- National institute for the mentally handicapped, Secunderabad
- National institute for the orthopedically handicapped, Kolkata

• Indian spinal injury center, New Delhi
• Artificial limbs manufacturing corporation of India, Kanpur
• District disability rehabilitation centers
Welfare programme/schemes for the rehabilitation of disabled in India ,,
The allocation of work related to medical component i.e., preventative, promotive, curative aspect is primarily planned, organized, and implemented by the Union Ministry of Health and Family Welfare, whereas rehabilitation is operated primarily by the nodal agency Union Ministry of Social Justice and Empowerment and administered by States/Union territories (UTs) through a number of stakeholders including ministries and department of Central/State Governments/UTs, Panchayati Raj Institutions (PRIs), Non governmental organizations (NGOs), disabled people organizations, advocacy groups, family and legal associations, experts and professionals for the welfare of disabled persons in the country. The program/schemes as proposed in Union Ministry of Social Justice and Empowerment are as follows:
Deendayal disabled rehabilitation scheme
The scheme provides support to the NGOs to deliver various rehabilitation services to people with disabilities. This includes support to schools for children with orthopedic, speech, hearing, visual and mental disabilities; vocational training centers to provide basic skills to PWDs; community-based rehabilitation program; half-way homes for psychosocial rehabilitation of treated and controlled mentally ill people; pre-school and early intervention programs; human resource development; support for setting up Braille presses; and placement services.

Funding is made available to established research and development centers, academic institutions, public sector industries, agencies undertaking research activities for the benefit of PWDs.
Concession offered by the Government of India to blind persons ,
According to guidelines by the Ministry of Social Justice and Empowerment, GOI, the minimum degree of disability should be 40% for an individual to be eligible for any concessions or benefits. State government also extends various benefits in addition to those initiated by the GOI.

Under the integrated rural development programme (IRDP), 3% quota is earmarked for physically handicapped persons.
| Definition of blindness and low vision|| |
In India, different definitions of disability are introduced for various purposes and as such, they have been based on various criteria. No single standard exists in India in order to evaluate disability. In common parlance, different terms such as disabled, handicapped, crippled, physically challenged are used interchangeably.  Visual acuity as well as field of vision has been considered for deciding blindness and in India it refers to a condition where a person suffers from any of the following conditions, namely: Total absence of sight; or visual acuity not exceeding 6/60 or 20/200 (Snellen) after best correction in the better eye; limitation of the field of vision subtending an angle of 20 degree or worse.
A person who after treatment of standard refraction has a visual acuity in better eye of <20/60 to light perception; or a visual field of <10° from the point of fixation, however, and is potentially able to use vision for planning or execution of a task [WHO].  Many persons especially children who have a corrected visual acuity of less than 3/60 in the better eye have useful vision and benefit from Low Vision services.
Generally, the impairment of 40% or more is considered a handicap. As percentage of impairment in the case of one-eyed person is only 30%, according to the approved definition in medical parlance, a person with one good eye is not a blind person [Table 1]. The Committee of the Ministry of Social Justice and Empowerment on Recommendation of Standard Definition of Disability recommended that one eye-eyed person should be excluded from the other categories of visual impairment so that facilities and concessions available to severely and profoundly visually impaired persons are not eroded. The committee, however, felt that loss of one eye would not be considered as a disqualification on medical grounds unless a particular post is of such a technical nature that it requires of a person to have the coordinated use.
| Evaluation and need assessment for low vision|| |
Visual impairment in general affects four main functional areas: Orientation/mobility, communication, activities of daily living (ADL) and sustained near vision task. Early intervention and special education can balance the negative effects of visual impairment. In many cases environmental adaptations, vision training, follow up for ensuring compliance, coordinating with stakeholders, removing myth and misconception and counseling would help in empowering the individual and/or enhancing functional residual vision.
The effect of low vision is not same for all people and the following assessment needs to be compiled for each individual before embarking upon the decision of assistive devices: 
- Extent of vision: Near and distance visual acuity
- Size of the visual field [if relevant]
- Effect of light and glare
- Extent of recognition and naming of colors
- Extent to which contrast affects their activities
- Extent of use of vision for different activities and purpose in the environment
- Extent to which a person sees and recognizes an object depends, amongst other on: Familiarity of the object; light; size; distance; contrast; color; detail or simplicity of the object
- Age, socioeconomic conditions, literacy status, and level of motivation
| Special assistive devices for the visually impaired|| |
Assistive devices for the visually impaired can be broadly divided into the following categories: Education, mobility, vocational, daily living devices, low vision devices, and psychological test for vocational assessment and training. ,
Education devices 
Braille duplicators and writers, for example, Brailler and thermoform machine to convert material into Braille; Writing devices: Braille slates, Taylor postcard frame, pocket Braille frame; Braille paper; talking books and tape recorders: Material recorded on cassettes has emerged as the most popular mode of imparting education; Reading machines: Kurzweil reading machine, which reads typeset or typewritten text and turns it into speech; Braille computers: Braille Windows, Index Braille, Braille'n speak helps individual while working with personal computers; Mathematical devices: The Taylor arithmetic frame, abacus, talking calculator, spur wheel helps in learning mathematics; Geography and science devices: Sensory quill and three-dimensional raised maps help in learning geography, human physiology, zoology, and botany.
Canes (symbol canes; guide canes; long canes; electronic travel devices), mobility show-card, mini beeper.
Goniometer, attachment to lathe, spot welding, continuity tester, Braille micrometer.
Daily living devices
Daily living devices can be further classified into five broad categories namely, clocks and watches, games and puzzles, sports, kitchen equipment and personnel devices.
Low vision devices
Low Vision devices can be further divided into two types: Optical devices, which use lenses to magnify objects and non-optical devices and techniques, which make objects easier to use. A third category is electronic magnifier which is sometimes subsumed under non-optical devices. These devices include telescopes (telescopic spectacles, hand held, tele-bifocal spectacles), visualtek, schmidt reader, magnifying lenses (fixed focus; variable focus stand; half cylindrical rod; hand magnifier; folding; high plus spectacle; half eye spectacle-prism glasses; clip on magnifier), microscopic spectacles, visolett, fluorescent reading lamps, tinted lenses. Electronic magnifier/adaptive technology in the form of closed circuit television (CCTV), computer software (JAWS, MAGIC, text Braille software), speech synthesizer, talking books, overhead projector. ,,,
Psychological assessment tests and training program is designed to develop a person's skill potential to the extent possible. These include Minnesota rate of manipulation test; Pennsylvania bi-manual work sample; Purdue pegboard; Crawford small parts dexterity test; Stanford-kolhs block design test for the blind; Blind learning aptitude test.
| New initiative on low vision services in approved 11 th five-year (2007-12) plan under NPCB|| |
Strengthening Low Vision service is one of the thrust areas under 11 th five-year plan under NPCB in addition to ongoing activities. Regional Institutes of Ophthalmology (RIO) and government medical colleges are being developed as Low Vision units in a phased manner. Financial assistance for Low Vision devices like high plus spectacles, hand held magnifiers, stand magnifiers, telescope, video magnifiers [closed circuit television], absorptive lenses; field expanding devices are being provided by NPCB especially for poor patients. Eye surgeons working in public sector are being provided seven days orientation training on Low Vision services and financial support is borne by the GOI. Technical guidelines and comprehensive resource on Low Vision services is being developed involving all stakeholders for reference and dissemination. Improving quality of life of persons suffering from visual impairment involve patience, perseverance, multi-disciplinary approach with efficient coordination amongst stakeholders including medical, paramedical, social/psychological and educational professional. The gap between need and availability of Low Vision services is known globally, however, a beginning has been made by the GOI to address this issue and fruitful results will be evident in times to come.
