How to interpret your prescription

Here are some common abbreviations used by your ophthalmologist:

• RE: Right Eye
• LE: Left Eye
• BR: Both Eyes
• ADD: Addition
• SFR: Sphere
• CYL: Cylinder
• FV: Far View
• CV: Close View
• VA: Visual Acuity
• IV: Intermediate Vision

Meaning of Values: The values ​​indicated in your recipe are expressed in quarters of diopters and have specific meanings:

• Far Vision: Values ​​preceded by a + sign indicate hyperopia , while those preceded by a - sign indicate myopia . Values ​​in parentheses refer to astigmatism , with the following value indicating the axis of astigmatism.

• Near Vision: Presbyopia , or tired eyesight, is indicated by the "ADD", which is always a positive value, representing the amount of additional correction needed to focus at close range.

Refractive Errors: Hyperopia , myopia and astigmatism are common refractive errors corrected with glasses and/or contact lenses.

• Hyperopia: Indicated by positive values ​​(+).

• Myopia: Indicated by negative values ​​(-).

• Astigmatism: It can occur in combination with other refractive errors and is represented by values ​​in parentheses, followed by the astigmatism axis.

Presbyopia: Additional magnifying power is required to focus near vision. This value is always positive and is calculated by subtracting the sphere for distance vision from the sphere for near vision.
