Buying Guide for the Best Stick On Bifocals
Choosing stick-on bifocals can be a great way to add reading power to your favorite sunglasses or regular glasses without needing to buy a new pair. These flexible lenses adhere to your existing eyewear and are especially useful for people who need help seeing up close but don’t want to switch between multiple pairs of glasses. To find the best fit for your needs, it’s important to understand the key features that affect comfort, clarity, and ease of use.Diopter StrengthDiopter strength refers to the amount of magnification the bifocal provides, usually measured in increments like +1.00, +1.50, +2.00, and so on. This is important because it determines how much help you’ll get with close-up tasks like reading or tying knots. Lower strengths (like +1.00 to +1.50) are good for mild vision correction, while higher strengths (like +2.00 to +3.00) are for those who need more assistance. To pick the right one, consider what strength you use in regular reading glasses or consult an eye care professional. If you’re unsure, starting with a lower strength is often a safe bet.
Lens Size and ShapeThe size and shape of the stick-on bifocals determine how much of your lens will be covered and where the magnification will be placed. Larger lenses provide a bigger reading area but may be more noticeable, while smaller ones are less obtrusive but offer a smaller field of magnification. Shapes can be round, oval, or rectangular, and the best choice depends on the shape of your glasses and your reading habits. If you only need a small area for reading, a compact shape works well; for broader tasks, a larger lens may be better.
Material and ClarityStick-on bifocals are usually made from soft, flexible plastic that can be trimmed to fit your glasses. The quality of the material affects how clear your vision will be through the bifocal and how comfortable it feels on your glasses. Higher clarity materials provide a sharper image and are less likely to distort your view. If you plan to use them often or for detailed work, look for options that emphasize optical clarity and comfort.
Ease of Application and RemovalThis refers to how simple it is to attach and remove the bifocals from your glasses. Some stick-ons use water to adhere, while others may use a gentle adhesive. Easy application is important if you plan to move them between different pairs of glasses or want to remove them frequently. If you’re looking for a temporary solution, prioritize options that can be repositioned or removed without leaving residue.
ReusabilityReusability means whether the stick-on bifocals can be used multiple times or if they are meant for one-time use. Reusable bifocals are more cost-effective and convenient if you want to switch them between different glasses. If you only need them for a specific occasion or short-term use, single-use options may be sufficient. Think about how often you’ll need to move or replace them to decide which type suits your lifestyle.
