Is there evidence that supports the Dot Glasses approach to vision care?

We have worked with many optometrists, ophthalmologists, eye care clinics and eye care hospitals. While all of them prefer providing perfect vision solutions provided by an optometrist or eye care professional, there is a general consensus that providing “good enough” vision is a good alternative to improve vision acuity when there is no possibility to get a proper eye exam, either because of cost or access.
