Locate the optical dataTabs A and B circled in yellow on our example will help to determine:
- A: The vision. Ex far vision , near vision, progressive lenses ( far vision and near vision) , intermediate vision.
- B : Advice on the type of glass recommended by the ophthalmologist and sometimes a type of treatment or tint .
Blue sphere : The sphere is a value either positive (case of hyperopia ) or negative ( in the case of myopia ) . The value is always notified with the sign + or - or with a score of 0 or plane. Do not forget to fill in the appropriate box the whole sphere value and its sign .
Cyl green: The cylinder (which exists only in the case of astigmatism ) is always notified in parenthesis with the + or - sign and must be associated with an axis (purple ) . Make sure to include the whole of the cylinder which consists of its value , its sign and its axis in the appropriate boxes . If nothing is noted in parenthesis the cylinder does not exist and therefore there is no axis.
ADD red: The addition is the additional value of far vision to get the near vision. This value varies from 0.75 to 3.75.
Below the specific example of what has been stated.
- Sph : +0.75
- Cyl : -1.00
- Axe : 10
- ADD : 1.75
