Cheap Oakley Sunglasses manufacturers may retain their own staff of designers or use outside consultants to design frames. The consultants often include fashion designers, who create their own lines of eye wear that change along with trends in clothing design. The designers’ names are important in selling eyeglasses and especially in interesting fashion-conscious buyers in multiple pairs of glasses or sunglasses. There are definitely trends or fashions in eyewear including light- or dark-colored frames, thick or delicate ones, and decorative shapes or ornament-bearing styles. Specialized frames for children and half-frames for reading glasses are also designed with an eye to style.
Designs also incorporate certain standards including bridge size and eye size. The bridge size allows for different thicknesses of the upper part of the nose where the nose pads on the glass’s rest. Three eye sizes are standard for the range of dimensions of corrective lenses. Each style is typically manufactured in four different colors, so a single style will result in 12 combinations of color and dimension. Frame designers and manufacturers typically produce a new style every few months and discontinue styles if they don’t sell well.
** Plastic Frames
Plastic frames can deliver a multitude of deep and vibrant colours, shapes and detailing.
With many lightweight plastics on the market today, they are comfortable as they allow for an even weight distribution across the nose.
Whilst they can be a little heavier and easier to break than metal alternatives, plastic can offer wearers hypoallergenic benefits, wrap-around styling, unique colours and blends, not to mention beautiful detailing.
Good quality metal frames can involve up to eighty different steps in order to produce them. Some metals such as titanium are even more complex. A typical metal frame can take up to four months to manufacture.
In general, metal is lightweight, strong, flexible and anti-corrosive, making them ideal for frame production.
To a large extent, the degree of quality control imposed on sunglasses manufacture is a function of the type of sunglasses. Inexpensive plastic models have little concern with optical perfection; they may contain flaws which will distort the wearer’s vision. On the other hand, expensive glass lenses strive for high optical quality and are checked accordingly. There are a variety of instrumental methods used to evaluate distortion of the finished lens, but one simple test is to simply hold the glasses at arms’ length and look at a straight line in the distance. Slowly move the lenses across the line. If the lens causes the line to sway or bend, the lenses are optically imperfect. For best results, look through the outer edges of the lens as well as the center.
