What Is a Glasses Prescription and Why Does It Matter?
A glasses prescription is a written statement from an eye care professional that specifies the required lens power and other specifications necessary for correcting an individual’s vision. It typically includes measurements such as sphere (SPH), cylinder (CYL), axis, and addition (Add) for multifocal lenses.
The American Optometric Association (AOA) defines a glasses prescription as a document that “provides specific measurements and optical details needed to create lenses that correspond to an individual’s vision needs.”
A glasses prescription mainly consists of the power needed to correct refractive errors, such as nearsightedness, farsightedness, and astigmatism. It also may include details about lens types, recommended lens coatings, and frame types.
The National Eye Institute explains that a glasses prescription may also provide instructions on how often an individual should have their eyes examined to maintain optimal vision health. Regular checks help detect changes in vision or eye health over time.
Common causes of vision issues include genetic factors, environmental influences, and aging. Conditions like diabetes and prolonged screen exposure also contribute to declining vision quality.
According to the World Health Organization, approximately 2.7 billion people need vision correction, and by 2050, an estimated 4.88 billion individuals will require vision correction globally.
Untreated vision problems can lead to accidents, decreased quality of life, and economic burdens due to reduced productivity. Poor vision can affect job performance and educational outcomes.
On a broader scale, improving access to glasses can enhance societal health, welfare, and economic participation. Better vision improves education and job opportunities, contributing to economic growth.
For affordable access to vision care, organizations like VisionSpring recommend providing low-cost eyeglasses and increasing eye care accessibility to underserved populations.
Strategies such as tele-optometry, community eye care programs, and awareness campaigns can help address visual impairment and promote regular eye exams among all age groups.
What Information Is Typically Included in a Glasses Prescription?
A glasses prescription typically includes information about a person’s vision requirements. This includes details such as the measurements needed to create effective corrective lenses.
The main components of a glasses prescription typically include the following:
1. Sphere (SPH)
2. Cylinder (CYL)
3. Axis
4. Addition (ADD)
5. Pupillary Distance (PD)
6. Prescription Date
These components provide essential insights into a person’s visual needs and are crucial for manufacturing glasses.
-
Sphere (SPH):
The sphere (SPH) measures the degree of nearsightedness (myopia) or farsightedness (hyperopia). This value is expressed in diopters (D). A negative sign indicates myopia, while a positive sign indicates hyperopia. For example, a prescription reading -2.00 means the individual is nearsighted. -
Cylinder (CYL):
The cylinder (CYL) indicates the amount of astigmatism present in an individual’s vision. Astigmatism causes blurred vision due to irregular curvature of the eye. This measure also is recorded in diopters and may be a negative or positive value. An example could be -1.25, indicating the individual has a moderate level of astigmatism. -
Axis:
The axis represents the orientation of astigmatism correction. It is measured in degrees, ranging from 1 to 180. The axis does not have a power value but complements the cylinder measurement to provide effective correction. -
Addition (ADD):
The addition (ADD) value applies to multifocal or bifocal lenses and indicates the extra lens power needed for reading or close work. This value is also measured in diopters and is typically a positive number. For instance, +1.50 may be noted for a person who has difficulty seeing up close due to presbyopia. -
Pupillary Distance (PD):
Pupillary distance (PD) is the distance between the centers of a person’s pupils. This measurement is crucial because it ensures that the optical center of the lenses aligns with the wearer’s pupils, allowing for optimal visual performance. PD is typically recorded in millimeters. -
Prescription Date:
The prescription date provides information about when the vision test was completed. This date is essential for determining the validity of the prescription, as vision can change over time. Prescriptions usually remain valid for one to two years, depending on the regulations in the region.
Understanding these components can help individuals select the right corrective eyewear along with discussions with vision care professionals.
How Can You Find Your Existing Glasses Prescription?
