Custom optical lenses are created for a specific purpose, which is to correct eye defects and correct eye alignment problems. The objective of this design process is to reshape the lens such that it is free of chromatic aberration and offers optimal resolution at all distances. Custom lenses are generally made from one of two different materials: polycarbonate and gas-permeable silicon hydro gel. These two materials differ in the thickness of their protective coatings. The thickness of a silicon coating is dependent upon the objective of the lens: it may be to correct astigmatism, increase contrast, or decrease glare.
In addition to the coatings, there are other design features to consider when designing custom optical lenses: power settings, coating thickness, and material selection among other things. With the invention of computer aided design (CAD) technology, the accuracy of these processes has increased dramatically. As such, custom manufacturing companies can produce accurate and high quality custom lenses that are virtually indistinguishable from commercially available models. However, even with computer aided design capabilities, precise detailing of an individual's vision disorder or eye condition is still necessary to ensure proper fit and result.
When ordering custom optical lenses, you will first need to work with your custom lens manufacturer to determine the specific correction options that your particular eye condition requires. In order to make the most appropriate design for your needs, your custom lens manufacturer must know the characteristics of your eye, including its focus, resolution, and field of curvature. You will also be able to choose among various materials and coatings, among other things. The lenses may be toric, spherical, and even binocular.
If you do not know anything about how to read prescription lenses but still require some type of corrective lens, your custom optical design company can provide some helpful assistance. They can help you assess the needs of your particular situation and then create a design solution that addresses those needs. For example, if you have nearsightedness, your custom lens manufacturer can often provide custom components that improve image clarity by eliminating some of the light-scattering effects of your eye's cornea. In addition, they can provide designs that minimize the distortion of your image caused by your nearsightedness, such as a reduction in the "fog" effect.
Once you have decided on the specific design elements that you need, your custom lens manufacturer can provide you with affordable production kits that will allow you to manufacture, test, and deliver your custom optical design components. From there, you will be able to complete the final testing and production process in-house. This means no additional expense for having your components produced, tested, and delivered for you. Most companies also offer ancillary services that will allow you to quickly and efficiently complete other tasks related to manufacturing, such as packaging and shipping your product.
Customized optical components can address a variety of vision issues, including near and far sighting, astigmatism, myopia (nearsightedness), and farsightedness. They are also available in a wide array of colors, including red, green, yellow, blue, and black. Custom lenses are made using polycarbonate or high index materials to reduce abrasion and increase wear resistance. Typically, the larger the objective diameter of your lenses the less they will cost to manufacture. Visit this website for more details: pfgoptics.com
