As essential as regular eyeglasses are to those with vision problems, prescription sunglasses are equally as significant, if not more so, in ensuring full and effective vision support in all lighting conditions. While aesthetic allure is certainly a factor that goes into choosing the best pair of prescription sunglasses, other crucial considerations involve lens material, frame size, lens coatings, and much more. This guide serves as a comprehensive manual to navigating these considerations in order to select the perfect pair of prescription sunglasses tailored specifically for your needs.
Why Prescription Sunglasses?
Prescription sunglasses are a hybrid of your standard eyeglasses and sunglasses. By offering vision correction and sun-protection in one stylish package, they eradicate the need to swap between spectacles and sunglasses, or even worse, attempting to wear both at the same time. Prescription sunglasses cater to myopia, hyperopia, and astigmatism, giving you the liberty to experience uncompromised vision even under the glaring sun. UV protection is another benefit, safeguarding your eyes from the damage caused by harmful UV rays that can lead to cataracts and macular degeneration. Plus, they don't only serve a functional purpose. Prescription sunglasses are available in diverse and attractive styles just like your regular eyewear, enabling you to uphold your fashion statement.
Factors to Consider When Choosing Prescription Sunglasses
Frame Size and Shape
Choosing the right frame size and shape for your prescription sunglasses is as much a decision dictated by personal preference as it is a matter of functional necessity. Frames come in varied shapes such as oval, circle, square, rectangle, and wayfarer - each suitable for a different facial shape. For instance, round sunglasses could flatter a more angular face, whereas rectangular frames may be more suited to those with softer facial features. Larger frames can provide added sun protection, covering more area, while smaller frames are typically chosen for their style.
Lens Material
Lens materials are classified primarily into three types: plastic, polycarbonate, and high-index plastic lenses. Plastic lenses, also known as CR-39 lenses, are inexpensive but lack durability and aren't recommended for high prescriptions. Polycarbonate lenses, on the other hand, are robust and lightweight but might have lesser optical clarity compared to high-index lenses. Lastly, high-index plastic lenses are the most lightweight and suitable for high prescriptions, although they can be costlier due to their top-grade qualities.
Lens Coatings
Lens coatings enhance the performance and durability of your prescription sunglasses. UV coating is a non-negotiable feature, reducing the risk of UV-induced eye problems. Anti-scratch and anti-reflective coatings minimize scratches and cut down on glare, improving the vision and longevity of the glasses. Hydrophobic coatings are perfect for those with an active lifestyle, preventing water or sweat smears.
## Type of Prescription Lenses
Determining the type of lens depends mainly upon your vision requirements. Single vision lenses comprise one prescription throughout the entire lens and are suitable for those needing correction for only one field of vision (near or far). Bifocal lenses split the lens into two prescriptions - the upper section for distance and the lower for near vision, serving those with presbyopia. Progressive lenses (also called multi-focal or varifocal lenses) offer a smoother transition between distance and near prescriptions compared to bifocals, with an added intermediate prescription for computer use. Trifocal lenses expand upon bifocals by having three prescriptions for distance, intermediate, and near vision.
Popular Styles and Brands
With brands like Ray-Ban, Oakley, and Gucci offering their iconic styles in prescription forms, you are not limited when it comes to choosing fashionable prescription sunglasses. Some popular styles include the timeless aviators, the versatile and casual wayfarers, and the edgy square frames. Each of these brands also offer durability and comfort alongside their distinct styles.
Caring for Your Prescription Sunglasses
To maintain the quality of your prescription sunglasses over time, a proper cleaning regimen is necessary – use a microfiber cloth and a specialized lens cleaning solution. Also, make sure to store them in a sturdy glasses case when not in use to protect them from scratches or mishaps. Handling your sunglasses gently extends the lifespan of the lens coatings and the frame's finish.
Essential Tips
Regular eye examinations ensure your vision prescription is up-to-date, aiding in the effectiveness of your prescription sunglasses. It's also important to know when to upgrade your sunglasses - blurry vision, constant headaches or discomfort are signs that may indicate it's time for a new pair.
