BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Globally, at least 2.2 billion people are estimated to have a vision impairment or blindness, of whom at least 1 billion people have permanent vision impairment. People with repairable vision impairment includes those with moderate or severe distance vision impairment or blindness due to unaddressed refractive error, cataract, glaucoma, corneal opacities, diabetic retinopathy, and trachoma, as well as near vision impairment caused by unaddressed presbyopia.
[0004] In various researches it is found that in terms of regional differences, the prevalence of distant vision impairment in low- income regions and middle-income regions is estimated to be four times higher than in high-income regions. Moreover, population growth and ageing will increase the risk that more people acquire vision impairment.
[0005] There are variations in causes of vision impairment across countries. For example, the proportion of vision impairment due to cataract is higher in low- and middle-income countries than high-income countries. In high income countries, diseases, such as diabetic retinopathy, glaucoma and age-related macular degeneration are more common.
[0006] Among children, the causes of vision impairment vary considerably across countries. For example, in low-income countries congenital cataract is a leading cause, whereas in high income countries it is more likely to be retinopathy of prematurity.
[0007] Visually impaired people find it very difficult to complete even normal tasks. Moreover, such people, especially people who have lost their eye sight completely, may confront significant challenges in identifying currencies, hence they find it very cumbersome and tough to perform transactions, such as purchasing or selling a product, paying for services, such as, auto rickshaw and cab drivers, etc.
[0008] With the advancement of technology, it becomes an exceptionally dreary task for the visually impaired individuals to carry multiple devices and furthermore this prompts for a huge spending, which normally is unreasonably expensive for some.
[0009] There are numerous wide ranges of devices having various features, such as, talkback feature, braille watches to feel the sensations in the native language of the visually impaired, traditionally available watches with large printed bold numbers as well as printed letters, etc.
[00010] There is, therefore, a need in the art to provide a solution to mitigate above-mentioned and other problems, and to provide a reliable, cost-effective, easily portable, and user-friendly device.
