Things You Must Know Before Buying Glasses

Whether you’re a seasoned eyeglass wearer or shopping for your first pair, buying glasses can be an overwhelming experience. With so many options, styles, and technologies available, making the right choice can seem daunting. However, armed with the right knowledge, you can confidently select the perfect pair of glasses to suit your needs and style. In this article, we’ll delve into the essential things you must know before buying glasses.

  1. Get Your Prescription

Before you start browsing frames, it’s crucial to have an up-to-date prescription from your eye doctor. Your prescription contains specific details about your vision, such as the degree of nearsightedness or farsightedness and any astigmatism correction needed. Without this prescription, you won’t be able to order glasses with the correct lenses. Eye exams are typically recommended every two years, but consult your eye care professional for personalized advice.

  1. Understand Your Prescription

Your eyeglass prescription consists of several abbreviations and numbers. Understanding what these mean will help you choose the right lenses for your needs:

  • OD and OS: These stand for “oculus dexter” and “oculus sinister,” which mean right eye and left eye, respectively.
  • Sphere (SPH): Indicates the level of nearsightedness (-) or farsightedness (+). The higher the number, the stronger the prescription.
  • Cylinder (CYL): If present, this corrects astigmatism.
  • Axis: Works in conjunction with the cylinder to correct astigmatism.
  • Add: For bifocal or progressive lenses, this represents the additional correction needed for reading or close-up work.
  1. Lens Materials and Coatings

Choosing the right lens material and coatings is essential for comfort, durability, and clarity. Some common lens materials include:

  • Plastic (CR-39): Lightweight and affordable but less durable than other options.
  • Polycarbonate: Lightweight, impact-resistant, and ideal for active lifestyles.
  • High-Index: Thinner and lighter than plastic, perfect for strong prescriptions.
  • Trivex: Lightweight and impact-resistant like polycarbonate but provides better clarity.

Coatings, such as anti-reflective, anti-scratch, and UV protection, can enhance your overall experience with glasses. Anti-reflective coatings reduce glare and improve night vision, while UV protection shields your eyes from harmful sun rays.

  1. Frame Styles and Materials

Frames come in various styles and materials, each with its unique aesthetic and practical attributes. Here are some popular options:

  • Full-rim frames: These frames fully encircle the lenses and provide excellent durability and stability.
  • Semi-rimless frames: Offer a more minimalist look, with only a frame on the top half of the lenses.
  • Rimless frames: Barely visible and lightweight, these frames offer a nearly invisible look but may be less durable.
  • Metal frames: Known for their sleek, modern appearance and durability.
  • Plastic frames: Lightweight and available in various colors and styles.

When selecting a frame, consider your face shape, style preferences, and comfort. Frames should complement your facial features and personal style.

  1. Frame Fit

Proper fit is crucial for both comfort and functionality. An ill-fitting frame can lead to discomfort, headaches, or vision problems. Here are some tips for finding the right fit:

  • Ensure the frames sit comfortably on your nose without slipping or digging in.
  • The temples should rest gently on your ears without pressing too tightly.
  • Your eyes should align with the optical center of the lenses.
  • Check for any adjustments needed by a professional to customize the fit.
  1. Consider Your Lifestyle

Your lifestyle plays a significant role in choosing the right glasses. Consider your daily activities, such as work, sports, or hobbies, when selecting frames and lenses. For example, if you’re an active person, you may opt for durable, impact-resistant lenses. If you spend long hours on the computer, you might want lenses designed for digital screen use to reduce eye strain.

  1. Budget Wisely

Glasses come in a wide range of price points, so it’s essential to set a budget before you start shopping. While it’s tempting to splurge on designer frames, there are plenty of affordable options that offer quality and style. Additionally, be aware that insurance plans may cover part or all of your eyeglass expenses, so check your policy for details.

  1. Try Before You Buy

When you find frames you like, try them on to ensure they suit your face shape and style. Most optical stores allow you to try on frames before making a decision. Don’t hesitate to ask for assistance from store staff; they can provide valuable insights and help you find the perfect pair.

  1. Online vs. In-Store Purchases

Today, you have the option to buy glasses online or in a physical store. Each approach has its pros and cons. Online shopping can be more convenient and cost-effective, but it may be challenging to assess fit and comfort without trying frames on. In-store purchases offer a personalized fitting experience but may come at a higher cost. Consider your priorities when deciding between the two.


Buying glasses doesn’t have to be a daunting task. Armed with your prescription, an understanding of lens materials and coatings, frame styles, and a budget in mind, you can confidently navigate the world of eyewear brands. Remember that finding the perfect pair of glasses not only enhances your vision but also complements your style and lifestyle. Take the time to explore your options, try on different frames, and seek professional advice to make an informed decision. Your new glasses should not only help you see better but also make you feel and look great.
