My eyeglasses prescription

What is it:

An eyeglasses prescription is an order written by an optometrist or ophthalmologist, that specifies the value of all parameters the prescriber has deemed necessary to construct and/or dispense corrective lenses appropriate for a patient

How to read Example, printed version:

R and L
‘R’ refers to your right eye, ‘L’ to your left.

SPH (sphere)
The amount of power required to correct your vision.

Plus (+) lenses are used to correct long sight.

Minus (-) lenses to correct short sight. The higher the number, the stronger the lens required.

CYL (cylinder)
Amount of correction (if required) to remove any visual distortion, caused by an irregularly shaped cornea known as an astigmatism.

The direction that the cylinder (if required) will be built into your lenses to correct your astigmatism. It is measured in degrees between 0 and 180

Any correction (if required) to help balance your eye muscles so they work as a pair more comfortably.

The direction that the prism (if required) will be built into your lenses.

ADD Near

This is the amount of correction that must be added to your distance prescription to enable you to see near objects clearly, such as reading a book or map.

Where to get it measured:

Any Optometrist or Ophthalmologist office, or at Easy Optic Vision Center in Prague
Do you want to buy only frames or also lenses?
Do you want to buy just the sunglasses or sunglasses with corrective lenses?
