In reality, how much the numbers obtained by application can be precise? According to the above report, it is claimed that:

We have also tested the application and found out that the results are completely precise. Numbers shown by the application have been completely conforming to those prescribed by optometrist.

Limitations

Performing test with this application has some limitations as well, being completely explained at home page of it. If numbers of glasses would be out of negative 6 for myopia and up to positive 3 for hyperopia and more than 2.5 for astigmatism, detecting correct numbers of glasses by the application is not possible. In case numbers of glasses would be higher than above mentioned numbers, there would be no output by the application.

Also according to the Report:

Such limitations also have been proved through tests. Numbers of glasses being higher than negative 6 means severe myopia and about positive 3, it means average myopia. However, positive 5 would be considered as severe hyperopia. Precise measurement out of aforementioned values is not possible by cell phone and referring to optometrist would be best idea.
