Astigmatism tests include: Visual acuity: You read letters on a distance chart and receive a measurement (for example, 20/20 or 20/40). Alternative methods are used for young children and non-verbal patients. Keratometry/topography: This instrument measures the curve of your cornea.
Can you get glasses for reading and distance?
Progressive lenses have three prescriptions in one pair of glasses. That allows you to do close-up work (like reading a book), middle-distance work (like checking out a website on a computer), or distance viewing (like driving) without needing to change your glasses. They’re sometimes called multifocal lenses.
