The popularity and appeal of gradual injection sunglasses, or fashion injection glasses as they are sometimes called, can be attributed to the outstanding durability and flexibility that come with their innovative production process. As in the preceding sections, these injection shades are manufactured using an advanced technique of molding, and this feature gives them a contemporary and elegant look. Injection shades are designed into several trendy designs, which are determined by the prevailing fashion trends, the occasion, and the preferences of individuals. These cateye shades are sleek and stylish, perfect for modern women's fashion. Below are some of these contemporary styles:
Contrary to traditional angular-cut sunglasses, round injection glasses bring a unique and dazzling shape to the eye fashion, making them more appealing. Both the lens and frame materials are made from polycarbonate or TR90 using the injection molding processes to produce lightweight and impact-resistant glasses.
An aviator injection glasses style combines the traditional appeal of the aviator shape with the advantages of injection molding. The lenses of this style are generally large and teardrop-shaped, providing a good vision and blocking light. These glasses can be made of polycarbonate, and they are very light in weight, thus comfortable for long wear.
Cateye sunglasses are a form of gradual injection glasses that offer a vintage and luxurious feel in a sundry way. The frames are upturned on the outer edges, which gives a sophisticated and daring feminine outlook. This style is produced using highly durable plastics through the process of injection molding. They are trendy and long-lasting.
The wayfarer injection glasses resemble the classic wayfarer shades but with an innovative construction twist. Unlike the original wayfarer shades made from glass or traditional plastics, these shades are made through injection molding using highly flexible and robust plastics like polycarbonate and TR90. This offers better comfort and durability.
As the name suggests, oversized gradual injection glasses are popular due to their large lens and fashionable design. The frames can give maximum sun protection and are made from light but very durable materials, polycarbonate, and TR90, which are compatible with injection molding.
Injection sunglasses are made of different plastic materials through the process of injection molding in the forming of their frames and lenses. Some of these materials are stated below:
Polycarbonate
Injection sunglasses are famously made from polycarbonate, which makes them robust, secure, and light. Polycarbonate lenses are 10 times tougher than regular glass lenses and remain unbroken by impacts.
TR90
TR90 is a Swiss-formulated elastopolmer. It is famous in the eye fashion mainly due to its lightweight characteristic, robust structure, and flexibility that offers comfort even after hours of wear. Under breaks, the TR90 frames do not shatter into hazardous fragments but rather into safe pieces.
Acetate
Acetate is another material generally applied in the making of injection shades. Although it might not have the same level of strength as polycarbonate or TR90, Acetate has great optical clarity and is often applied in the making of lenses along with frames.
Injection Molded Sunglasses
Injection molding is a highly efficient production technique of sunglasses for fashion where diverse types of plastic materials are combined through the melting and injecting process in molds set for their shape. The typical fashion injection glasses manufacturing process is as follows: The process begins with the selection of plastic materials such as polycarbonate, TR90, or acetate.
Lens Creation
In this step, the lenses used in the gradual injection molding glasses are also prepared using efficient materials like polycarbonate or CR 39. These materials are cut into required shapes for the lenses as per the standards of the designed sunglasses.
Molding Process
During the injection molding process, the selected plastic material is melted to attain a moldable consistency. The molten plastic is then injected into moulds created for the frames. Once the plastic cools and solidifies, the frames are obtained from the moulds.
Assembly
After the frames and lenses are ready, assembly follows. This involves inserting the lenses into the frames. The temples are then attached to support the shades while wearing.
The most striking feature of prescription sunglasses is that they combine prescription eyeglasses with the benefits of sunshades. Individual optical requirements are fully met in this dual functionality to provide vision competence with total eye protection against harmful sun rays. Here are some of the important benefits:
UV Protection
Prescription sunglasses are formulated to act as a filter against ultraviolet (UV) rays). UV rays have adverse effects on the eyes; thus, anti-UV lenses are highly significant. These lenses offer great protection for the eyes, averting possible damage to cataracts, macular degeneration, and corneal burns. The shades also protect the surrounding skin, thus preventing skin cancers.
Improved Vision Comfort
Bright outdoor lights can cause discomfort to the eyes. Prescription sunglasses are very helpful in such conditions. Polarized or anti-reflective coatings help reduce glare on shiny surfaces like water bodies or roads. The ambiance light control provided makes outdoor activities comfortable for individuals with light sensitivity.
Clarity and Sharpness of Vision
Prescription sunglasses are designed to meet the particular refractive errors in individuals, such as myopia, hyperopia, and astigmatism. The lenses are fabricated based on the eye care specialist's prescriptions. Thus, wearing these glasses, the users can enjoy clear and sharp vision, which ordinary sunglasses can't provide.
Convenience
Wearing prescription sunglasses is convenient because people who wear contact lenses and regular sunglasses don't require additional eyewear. They save such individuals the inconvenience of contact lens wear combined with regular sunglasses.
Enhanced Outdoor Activities
Clarity and protection from UV rays provided by prescription sunglasses increase visibility and comfort for outdoor activities such as driving, swimming, and hiking. Eye care from prescription sunglasses is a great way to enjoy outdoor activities.
Though light in weight and flexible, injection glasses are stylish and come in various trendy styles to suit the users' fashion taste. Thus, their selection depends on how one combines the material with the appropriate styling and other features. The following aspects must be considered before choosing gradually injected shades:
The right lens type will define the clarity and comfort level the injection shades offer. In this case, polarized lenses are a good option since they reduce blurriness, especially when driving or engaging in outdoor activities. Photochromic lenses are good prescription sunglasses that conveniently adjust to light changes; dark lenses block harmful UV rays.
For a good look, the injection shades should be stylish; however, their comfort should come first. The pair should sit snugly on the nose without slipping or leaving marks on the area around the nose. Check the temple design so that it does not press against the head.
Various styles of injection shades, like the cat-eye and aviator, suit different fashion styles. When choosing the fashion aesthetic, consider the usual outfits worn daily and the times of the year. Round shades fit a boho style, and wayfarers are classic and fitting with casual or professional attire.
Ensure that the fashion injection shades have proper lenses that filter 100% of UVA and UVB rays. This will ensure the eyes have total protection from sun damage.
Various brands and price levels are available regarding gradual injection shades. Generally, well-known brands provide quality products. However, good-quality shades at reasonable prices might be found without compromising quality.
