A new report published by the Royal National Institute of Blind People (RNIB), has found people are having to wait for up to six months to access support after losing their sight.
The figures show in at least five local authorities in Wales, people are waiting over 24 weeks to access rehabilitation support.
The charity says when people first lose their sight, basic skills such as making a cup of tea, preparing a meal and being able to get around safely, all have to be re-learnt.
That support, they say, should be provided through local authority social services.
RNIB Cymru's survey also found significant variations in staffing levels for rehabilitation.
The Welsh Local Government Association recommends a ratio of one Rehabilitation Officer per 50,000 of population.
Six local authorities in Wales only employ one Rehabilitation Officer, but their populations vary from less than 70,000 to over 126,000.
