Vintage eyeglasses are the perfect accessory to complete your retro look. This article delves into what to look for when purchasing original vintage spectacles and, more importantly, what to avoid. Some frames, although illegal to sell, are highly flammable and almost explosive! Learn how to distinguish these from safer options.
Spectacle frame fashions have evolved as dramatically as clothing hemlines. From the early 20th century to today, the materials and styles of eyeglasses have undergone significant changes.
Initially, eyeglass lenses were made from mineral quartz, which is relatively heavy. This weighty material was later replaced by glass in the early 20th century. Today, most lenses are made from lightweight plastics like allyl diglycol carbonate, commonly known as CR-39 (Columbia Resin 39). CR-39 is less than half the weight of glass, making it a popular choice for modern eyeglasses.
For those seeking even lighter options, polycarbonate lenses are available. These lenses are not only feather-light but also highly impact-resistant, making them ideal for safety eyewear. However, polycarbonate is prone to scratching, so modern lenses are often treated with a scratch-resistant coating.
Many people collect vintage frames to wear them, but there are several pitfalls to be aware of. Here are some key considerations:
All frames deteriorate over time, but metal-rimmed frames are the least susceptible. However, frames from the mid-20th century often have plastic-coated end tips and nose pads, which can deteriorate due to perspiration. Fortunately, these parts can usually be replaced by a good optical outlet.
Cellulose Nitrate: Developed in 1850, this material was used for movie film and briefly for spectacle frames. It is highly flammable and deteriorates over time, emitting an acid smell. It is now illegal to sell cellulose nitrate frames due to their dangerous nature.
Cellulose Acetate: Introduced in the 1920s, this material is stable and non-flammable. It is still used today but can become brittle if stored in overly hot conditions.
Perspex: Popular in the 1950s and 1960s for upswept cat-eye frames, Perspex is strong but brittle. It requires significant heat to adjust and can snap if not handled properly.
Other Materials: Various other materials like carbon fiber enjoyed brief popularity but are not covered in detail here due to space constraints.
With the exception of cellulose nitrate frames, most vintage frames are safe to wear. However, it's essential to consult with an eyecare practitioner to ensure the frames can accommodate your prescription lenses.
Not every frame will suit every prescription. The distance between the geometrical centers of the eye rims and the distance between your eyes can affect the fit and lens thickness. Your eyecare specialist can calculate the expected lens edge thickness for your chosen frame and prescription.
Plastic-rimmed frames need to be heated to fit around the lens bevel and then shrink back to hold the lens securely. This process can be risky with vintage frames, as their brittleness is not always apparent. Reputable companies selling vintage spectacles can provide an indication of the frames' robustness but cannot offer guarantees.
Vintage spectacle styles can add a unique flavor to your fashion sense. Whether you collect them to wear or for the pleasure of owning a piece of history, good luck with your hunting!
