I came across a certain plastic slate and was amazed when I learnt it was used by the blind to read and write. I wondered how such an invention was made possible and by who. the individual who told me so went ahead to show me a huge stock of the braille slates which he had for sale and it got me thinking. who actually buys these? for one, I know most blind people wouldn't be able to afford it at the rate of 4000 naira each. we have the blind or visually impaired amongst us in Nigeria, how can one get establishments and organizations to purchase these products and distribute them to those who need them but cant afford them.
