Navigating the world of vision correction can seem complex, especially when faced with a prescription that looks like a secret code. However, understanding your prescription is the first step in finding the best lenses for your eyewear. Whether you’re a first-time glasses wearer or a seasoned pro, getting to grips with your prescription can empower you to make informed choices about your vision needs. Let’s demystify the process and help you understand your prescription.
Understand Your Prescription
An eyeglass prescription typically includes a series of numbers and abbreviations that specify the strength of correction your eyes require. Here’s what you might see and what it means:
Sphere (SPH)
This number indicates the power of the lens needed to correct your vision. It’s measured in diopters (D). If the number has a minus sign (-), you’re nearsighted; if it has a plus sign (+), you’re farsighted.
Cylinder (CYL) and Axis
These numbers relate to astigmatism correction. The CYL number reflects the lens power needed to correct the irregular curvature of your eye, while the axis number, ranging from 1 to 180, denotes the orientation of this correction.
Pupillary Distance (PD)
PD measures the space between the pupils of your eyes in millimeters and ensures that the lenses are positioned correctly in relation to your pupils for optimal focus.
Addition (ADD)
This number is typically found in bifocal or progressive lens prescriptions and indicates the additional magnification required for reading or close work.
Understand Your Prescription: The Right Lenses
Once you understand your prescription, the next step is selecting the right lenses to match your vision needs and lifestyle.
Single Vision Lenses
These lenses have the same prescription power across the entire lens and are suitable for people who need correction for one field of vision—either distance, intermediate (computer), or near (reading).
Bifocal Lenses
Bifocals provide two distinct areas for different vision needs — one for distance and one for near vision — with a visible line separating them.
Progressive Lenses
Progressives offer a seamless transition between multiple vision fields, from distance to intermediate to near, without the lines seen in bifocal lenses.
Lens Materials
The material of your lenses affects their weight, thickness, and durability:
- Polycarbonate: Lightweight and impact-resistant, ideal for children or active lifestyles.
- High-Index: Thinner and lighter than standard plastics, these are perfect if you have a strong prescription and want sleeker lenses.
- Trivex: Similar to polycarbonate with slightly better optical clarity.
Lens Coatings
Various coatings can enhance the performance and longevity of your lenses:
- Anti-Reflective (AR): Reduces glare, reflections, and halos around lights, particularly beneficial while driving at night or using a computer.
- Scratch-Resistant: Minimizes the wear and tear on the lens surface.
- UV Coating: Offers additional protection against harmful ultraviolet light.
- Blue Light Blocking: Reduces exposure to blue light emitted by digital screens, which is believed to contribute to eye strain and may affect sleep patterns.
Where to Purchase Your Lenses
Once you understand your prescription and with your prescription in hand, you can buy lenses from:
- Local Opticians or Eyewear Stores: They offer personalized service and fitting.
- Online Retailers: Provide a convenient and often more affordable option with a wide selection.
- Optometrists or Ophthalmologists: Offer professional services with the purchase.
Questions to Ask When Selecting Lenses
- How will my lifestyle or daily activities influence my choice of lenses?
- What lens materials are best suited to my prescription strength?
- Would I benefit from additional lens coatings, and if so, which ones?
- Are there any new lens technologies that could enhance my vision or comfort?
What to Consider for Lens Maintenance
Taking care of your lenses is crucial to maintaining clear vision. Use a microfiber cloth for cleaning, avoid harsh chemicals, and store your glasses in a protective case when not in use.
Ensuring a Proper Fit
To get the best use out of your lenses, they need to be correctly fitted into frames that sit comfortably on your face. This is where the expertise of an optician can be invaluable.
Advances in Lens Technology
The eyewear industry is constantly innovating, with newer technologies like lenses that adapt to light conditions, better blue-light filtering, and improved progressive lens designs. Keep an eye on what’s new, and ask your eye care provider about options that could benefit you.
Understand Your Prescription: When to Update
Your vision can change over time, so it’s essential to have regular eye exams and update your prescription as needed, typically every one to two years or as recommended by your eye care professional.
