Philadelphia, PA - Buying prescription glasses online offers convenience and often significant savings over in-store options. However, ensuring a proper fit is paramount when choosing your frames without the luxury of trying them on first. One key factor is understanding frame size and shape – knowing the dimensions that match your face, like the frame width, bridge distance, lens height, and temple length, can lead to a comfortable and flattering fit.
Selecting the correct lenses and features is another important aspect of finding glasses that will work for you. The lens prescription should be updated and accurately entered when placing your order. Additional lens features, such as anti-reflective coatings, blue-light filtering, and UV protection, can also be crucial for your comfort and eye health, especially if you spend long hours in front of digital screens or outdoors.
Key Takeaways
- Proper frame fit relies on knowing your facial measurements.
- Accurate prescription input is crucial for online glasses orders.
- Lens features contribute to comfort and vision protection.
Understanding Frame Size and Shape
Selecting the right prescription glasses online involves more than knowing your eyesight numbers—it's about understanding how frame size and shape complement your unique facial features.
Determining Your Face Shape
To find the perfect frames, first determine your face shape. Oval faces, for instance, are versatile and can accommodate most frame shapes. Square faces benefit from round or oval frames to soften angles, while round faces are enhanced with angular frame shapes to add definition. Use your cheekbones, jawline, and forehead as reference points to gauge whether your face is round, oval, square, or heart-shaped.
Importance of Frame Dimensions
Frame size is crucial for comfort and style and consists of three key dimensions: eye size, bridge width, and temple length. These are usually measured in millimeters. Eye size ranges from around 40 to 62 millimeters; bridge width generally falls between 14 and 24 millimeters and temple length should be measured to fit from the edge of the frame to behind the ear, which can be anything from 120 to 150 millimeters. Correct frame width is essential to prevent the glasses from pinching your nose or sliding off.
Choosing the Right Frame Style for Comfort
Beyond measurements, the frame style also influences comfort. Look for styles that align with your daily activities and preferences. For example, lightweight materials and a snug fit at the temple are ideal for active lifestyles. Remember, you can receive your glasses delivered in 24 hours, but choosing a frame style that looks good and feels good for the long haul is essential. Lightweight and durable materials, combined with a properly balanced frame, will ensure your glasses sit comfortably and won't need constant readjustment.
Selecting the Correct Lenses and Features
When ordering prescription glasses online, choosing the right lenses and features is as critical as getting the frames' fit right. Lens options, coatings, and additional features can enhance your vision and comfort.
Decoding Your Glasses Prescription
Your glasses prescription contains specific parameters that will guide the lens selection. These include sphere (SPH), cylinder (CYL), and axis, which denote the power of your lenses and the correction needed for any astigmatism. Understanding these values is essential when inputting your prescription for your new glasses.
Various Lens Types and Coatings
Lens Types:
- Single Vision Lenses: Correct for one field of vision, either distance, intermediate, or near.
- Progressive Lenses: A multifocal lens that smoothly transitions from distance to near vision without visible dividing lines.
- Photochromic Lenses: When exposed to sunlight, these lenses automatically adjust from clear to dark.
Lens Coatings:
- Anti-Reflective Coating: Reduces glare, enhances appearance, and improves vision by allowing more light to pass through.
- Anti-Scratch Coating: Prolong the life of your lenses by making them more resistant to scratches.
- Blue Light Blocking: This may help to reduce eye strain by blocking the blue light emitted from digital screens.
Extras Worth Considering
Blue Light Blocking Glasses have gained popularity, especially for individuals who spend substantial time in front of computers. Additionally, considering durable coatings such as anti-scratch and anti-reflective properties can safeguard your lenses and enhance your viewing experience.
Conclusion
Purchasing prescription glasses online can be efficient and cost-effective. Before shopping, ensure you have an up-to-date prescription and know your pupillary distance (PD). With accurate measurements and an understanding of frame sizes, you can find a well-fitting pair of glasses. Post-purchase, adjustments from a professional may be necessary to achieve the perfect fit.
