Measuring glasses for clip-on sunglasses begins with understanding both your regular eyewear and the type of clip-ons you desire. Clip-on sunglasses are practical for those who don’t want to invest in prescription sunglasses. They are designed to attach directly to your existing prescription glasses, allowing you to switch from clear lenses to tinted ones without any hassle. The key to achieving a perfect fit lies in accurate measurements, ensuring that the clip-ons sit securely on your current frames without slipping or compromising your vision.
Gathering the Right Tools
Before embarking on your measuring quest, have the right tools at hand. A flexible measuring tape, a ruler, and perhaps a notepad for jotting down measurements are essential. You can use a more specialized eyewear measuring tool if you have one, but a standard flexible tape will do the job just fine. Having these tools on hand will allow you to make measurements precisely, which is crucial for comfort and usability.
Measuring the Width of the Lens
Start by measuring the width of each lens of your glasses. Lay your glasses flat on a surface with the lenses facing upwards. Use the measuring tape or ruler to measure from the outer edge of one lens to the outer edge of the other. Take note of this total width. This measurement helps you pick clip-ons that match the size of your lenses and ensures that they cover the area of your prescription lenses without leaving gaps or excess space.
Assessing Lens Height
Next, you need to determine the height of the lens. Measure from the topmost point of your lens down to the bottom of the frame. This is particularly important because clip-on sunglasses typically come in specific heights, and you want to ensure that they are large enough to provide full coverage without obstructing your vision. Record this measurement, as it will help narrow down your search for the right clip-ons.
Checking Frame Width
After obtaining lens measurements, it’s essential to check the overall width of the frame. Measure from one side of the frame to the other, just above where the lenses sit. This width helps manufacturers design clip-ons that can comfortably fit, supporting the glasses without causing any strain on the hinges. A properly fitting clip-on should match or slightly exceed the width of your frame, allowing it to sit comfortably.
Measuring the Bridge Width
The bridge width refers to the distance between your lenses at the part that rests on your nose. To accurately measure this, you can simply measure the distance between the inner edges of both lenses. If your frame has a pronounced nose bridge, ensure to take this into account as it affects how well the clip-on shapes to your face. This measurement is key, as it affects how securely the clip-on will sit and whether it provides comfort for extended wear.
Taking Note of Frame Shape
Different eyewear styles come in various shapes, such as round, oval, square, or cat-eye. Your glasses’ shape will influence which clip-ons you can utilize without compromising style or fit. When considering your measurements, take note of the general outline of your frames. Some clip-ons are designed specifically for certain frame shapes. Discuss your preferences with retailers or manufacturers to ascertain compatibility before making a purchase.
Understanding Lens Curvature
A major factor that often gets overlooked is lens curvature. Measuring the curve of your lenses helps identify clip-ons that will contour correctly to your existing lenses. You can check for curvature by looking at how the lens arcs away from the center. If your lenses curve significantly, look for clip-ons specifically designed to fit curved lenses, as they come with a better adherence to the lens shape and won’t pop off easily.
Consulting Size Guides
Many manufacturers of clip-on sunglasses provide size guides that correlate to specific measurements; make sure to consult these guides while shopping. Once you have your measurements—in terms of width, height, and curvature—compare them to the suggested sizes in the clip-on options available to you. By doing this, you can quickly eliminate options that won’t work for you while honing in on choices that suit your precise needs.
Trying Before You Buy
If possible, always try before you buy. Many optical shops offer a selection of clip-on sunglasses. If you can, visit a store and try different styles to gauge which ones fit best with your glasses. Testing them physically helps you become more aware of how they grip on your frame and how comfortable they feel while worn. Each pair’s weight and balance can differ significantly, and experiencing them in person can be incredibly beneficial.
Considering Additional Factors
Don’t forget to factor in the lens and tint types as well. Clip-on sunglasses come in a variety of shades, styles, and functionalities; whether you’re looking for polarized lenses for outdoor wear or mirrored finishes for fashion statements, there are options to suit every preference. Determine what you need based on your lifestyle and activities, like outdoor sports, leisurely beach days, or daily commutes, since this might influence your choice of clip-ons.
Maintaining Your Clip-Ons
After you successfully select and acquire your clip-on sunglasses, understanding how to maintain them is crucial for longevity. Ensure you clean both your regular glasses and clip-ons regularly to avoid smudges and scratches. Use a microfiber cloth and lens cleaner for optimal care. Additionally, store them in a protective case when not in use, which helps prevent damage when they aren’t attached to your glasses. Proper care will keep your clip-ons functional and looking great for years to come.
