If we have optometrists to measure vision accurately, can Dot Glasses provide a wider range of lenses to meet the prescription needs?

Dot Glasses provides ultra-cheap, one-size-fits-all frames that are suitable for any program, and we can provide lens powers in increments of 0.25 diopters if the local infrastructure allows for higher levels of stock.

However, as Dot Glasses are always delivered on site at the time of the vision test (at the cheapest price point possible), we only provide lenses for spherical errors (standard refractive errors). Compensating for cylindrical errors would require full customization (and thus, two-way logistics, and much higher prices).
