Contrary to popular belief sighted people often sees poorly and far and near{!LANG-a3debd1ae3a411b225d0f993cfe24330!}

Violation of the uniform curvature of a lens leads to another violation of the refraction of the eye astigmatism{!LANG-284d4658637448bc18f496d39336134b!}

Correction of myopia, hyperopia and astigmatism is with glasses, contact lenses, surgical or laser correction.{!LANG-c79c6745ac6d0b026294d8b8077882c5!}

And glasses and contact lenses have their pros and cons. So, {!LANG-b3d4a452fabc03dd1a22d87875cfa08f!}. First, it's cheap – once buying glasses, you can forget about a re-purchase.

I have glasses 3.5 D read and 1.2 D for driving and not only. 1,2 glasses well see the road but can't see the readings on the display of the dashboard of the car. Question: if I change my glasses for contacts – I can equally see both distance and near?
