What is an ADD Number in My Glasses Prescription?
An ADD number in a glasses prescription signifies the additional magnifying power needed for near vision. It is commonly used in multifocal lenses, such as bifocals or progressive lenses, to assist individuals with presbyopia, a condition that affects the ability to focus on close objects.
The American Optometric Association (AOA) defines the ADD number as the “additional power needed for the lower part of multifocal lenses” to correct near vision. This power is added to the patient’s distance prescription to accommodate close-up tasks like reading or sewing.
The ADD number typically ranges from +0.75 to +3.00 diopters, depending on the individual’s vision needs. It is determined during an eye examination, where the eye care professional assesses the patient’s ability to see clearly at various distances. The higher the ADD number, the stronger the lens for near vision.
According to the Vision Council, nearly 80 million Americans are affected by presbyopia, making the ADD number critical for many. This number ensures that multifocal lenses are tailored to the user’s specific vision requirements.
A higher ADD number can signify more pronounced difficulties with near tasks. Many people are unaware of their presbyopia until they experience difficulty reading or performing close-up work.
To enhance patient understanding, eye care professionals emphasize regular comprehensive eye exams. They also recommend using proper lighting and correct reading distances to assist with presbyopia.
In conclusion, the ADD number is crucial for those needing multifocal lenses, as it directly impacts their ability to see clearly at close range. Regular follow-ups with eye care professionals will ensure optimal visual comfort and health.
