When shopping for single vision lenses, it’s essential to understand your prescription single vision eyeglasses correct one area of vision, near or far. This will help you to get started with selecting lenses that are right for you and your needs. If you’re new to glasses or if it’s time to get some new ones, the right pair of lenses can really make a difference in terms of comfort and clarity.

Also, these days, lots of people go online to buy glasses, though it’s never a bad idea to check for some trusted advice. For instance, an in-depth guide to glasses frames can help you choose the right frames for your face and your lifestyle.

Understanding your prescription

It is imperative to know what prescription you need in order to correct your vision BEFORE ordering any single vision lenses. Single Vision Lenses: This type of lens is made to correct either one type of vision condition, or the other—nearsightedness (myopia) or farsightedness (hyperopia). It’s also essential to be aware if you have astigmatism, which may necessitate special corrective lenses.

Key considerations:

  1. Distance Lenses (Myopia): Myopia lenses, or distance lenses, allow you to see objects in the distance sharply. People with myopia need glasses to be able to see, say, the road or a movie screen.
  2. Far-Sighted (Hyperopia): These lenses enhance near-vision performance, enabling one to read, work on a computer, or look at a smartphone.
  3. Astigmatism: If you have astigmatism, you may require special lenses to help shape your eye and provide better clarity. They may also have either myopia or hyperopia combined with astigmatism, so consider multi-directional as well.

It’s always smart to double-check your prescription before you buy lenses. There have been stories of clients buying lenses for an old prescription only to find that the vision is blurred and their eyes feel uncomfortable. Before you buy, be sure to have an updated prescription from your optometrist.

Tip: Visit an eye doctor regularly to review the accuracy of your prescription. Those eyes change over time, and keeping up with changes is important for clear vision.

Lens materials and coatings

Selecting the correct lens material is also important in the way of comfort, durability, and clarity of vision.

Here’s a closer look at the most common lens materials:

  1. Polycarbonate lenses: They are lightweight and resistant to impacts, suitable for kids or people with active lifestyles. Polycarbonate lenses can be an ideal option for those who tend to be a little accident-prone or lead a more active lifestyle that involves outdoor and sports activities.
  2. High-index lenses: Thinner and lighter, they are for people with stronger prescriptions. For higher prescriptions, they are much more comfortable than office lenses and are more attractive too.
  3. Plastic lenses: These are less expensive and offer good durability for a typical prescription. Plastic lenses are typically standard, and for good reason: People without very strong prescriptions have been known to throw a pair in their purse, and toss them when they’re ready for a new look.

Lens coatings that coat your lenses:

  1. Anti-reflective coating: This cuts down on glare from digital screens as well as from nighttime headlights. For computer users or for other people who are on a screen a lot, an anti-reflective coating will minimise eyestrain and enhance visual comfort.
  2. UV protection: Not only will this keep your eyes safe from glaring sun rays, but long-term UV exposure can lead to eye conditions like cataracts, so make sure your sunglasses offer it.
  3. Scratch-resistant coating: This keeps your lenses fresh and free from scratches. For those of us who are always on the move, scratch-resistant lenses are the ideal choice for keeping things clear.

For most of my patients, polycarbonate lenses with anti-reflective coating are the way to go, especially for people who spend a lot of time on the computer or other electronic devices. These lenses minimise eye fatigue, helping people feel more comfortable.

Tip: Opt for UV protection lenses if you spend time outside or drive often. UV rays can cause long-term damage to your eyes, and it's better to be safe than sorry.

Frame selection and fit

Once you’ve selected the right lenses, it’s time to focus on the glasses frame. After you choose the right lenses, it’s time to pick a glasses frame. Not only should it fit well, but it should also suit your face shape and personal style. Frame choice also may impact your comfort and how often you want to wear your sunglasses, so it’s important to make the right decision.

Key considerations:

  1. Fit: A too-snug frame can hurt, but a loose one might slide down your nose. Make sure the frame rests comfortably on the bridge of your nose and doesn’t pinch. Fit is key, especially if you wear glasses all day.
  2. Style: The style of your frame can reveal a lot about your personality. If you like yours chunky and bold or bare and spare, there’s an extensive range to shop. Decide what suits your personality and lifestyle the most.
  3. Weight: Lighter frames, whether plastic, acetate or titanium, wholly provide comfort for extended wearing. Big frames can be heavy on your face, and heavy frames can be, well, heavy over time, especially if you use glasses all day long.

It’s important to try on multiple frames in-store to ensure the best fit. I had a client who initially bought a pair of heavy metal frames but found them uncomfortable after wearing them for just a few hours. They ended up exchanging them for lighter, acetate frames, which made a huge difference.

If you’re unsure about which frames to choose, consider checking out a guide to choosing glasses frames to better understand your options and make an informed decision.

Tip: Try on frames in person to assess comfort, fit, and style before committing to an online purchase. Online stores may not always offer the full range of fitting options you can test in person.

Balancing cost and quality

As a buyer of single vision lenses, you will need to consider your budget to determine how much do lenses cost and to decide where to skimp and where to splurge. Though it might be tempting to spring for something less expensive, remember that the quality of your lenses and frames directly influences the way you see and feel. Good quality lenses and frames are both functional and fashionable investments.

How to shop smart:

  1. Shop deals: Many optical shops offer sales, especially around holidays or promotional events. Make the most of these opportunities without being held back by the quality of your lenses.
  2. Buy online: The pricing might be better if you buy online, but be confident in the reseller, as well as the warranty or ability to return. Don't forget to also take into consideration customer reviews and ratings.
  3. Don’t cheap out on lenses: Sure, there are cheaper lens options, but higher quality lenses produce better clarity and last longer. If you have an intricate prescription, going for high-quality lenses will ensure a better experience.

The clients of mine who go for budget lenses always come back for better glass because the budget ones didn’t give them what they needed. It’s worth spending a little more for better comfort and vision.

Tip: Set a reasonable budget, but prioritise lens quality to ensure long-term comfort and clarity.
