Lenses
The lenses prescribed by your optometrist are determined by your prescription and, with new advances in technology, there are more options available than ever before. Whether you are in need of a multi-focal lens or just a new pair of readers, Optometrics of Chatsworth prefers to offer the latest and best lenses available in order to provide our patients with the best possible vision.
Our on site lab also means that you have less waiting time for eyeglass repairs and same day service for many prescriptions. (This does not apply to eye wear orders with Vision Plans).

New Lens Technology
Progressive Lenses
There are several different types of lenses available and what you're prescribed depends upon which part of your vision needs correction. Most people are familiar with single vision, bifocal and/or trifocal lenses; however, there still seem to be plenty of questions about progressives, particularly how they work.
Unlike the other multi-focals, progressive lenses do not contain any lines and the change between powers (the strength and type of vision correction) is much more gradual. Progressive lenses actually contain many lens powers which "blend," therefore lessening the amount of effort required to change focus between distances.
Although wearing progressive lenses for the first time does require a bit of an adjustment, advances in technology have drastically improved their design and there are several high end brands available now that often don't require any adjustment at all. Optometrics of Chatsworth prefers to prescribe the highest quality of progressive lenses to our patients in order to give them the best vision possible and we've often heard the difference in quality described as driving a Rolls Royce after riding a bicycle all your life. They may be a bit higher in cost but our patients always appreciate the quality of vision from the moment they try them on.
High Definition Lenses
High definition lenses are designed to provide sharper and more clear vision in all conditions. Unlike the other lens classifications, "high definition" does not refer to the correction of a visual field, but rather to an improvement in lens quality due to more advanced manufacturing processes.Traditional manufacturing tools and processes do not always produce lenses that completely correct a visual impairment; while the lenses may contain the right power to improve a distance prescription, the process by which they are made may not be advanced enough to have an affect on additional high-order aberrations. (HOAs are more complex vision errors that can be caused by irregularities in the eye's refractive components).
High definition lenses are able to correct or more significantly reduce the effects of more complex visual impairments through superior manufacturing processes and improved lens customization techniques.

Additional Lens Options
Anti-Reflective Coating - This coating not only improves your vision through your lenses, but also improves the overall appearance of your eyeglasses. Anti-Reflective coatings eliminate reflections of light from the front and back surface of eyeglass lenses. By diminishing the amount of reflections, more light is able to pass through the lenses - which assists in better vision - and eyeglasses appear much more attractive because of the lack of glare on the surface of the lens.
Polarized - Polarized lenses also reduce glare but, rather from direct light, it reduces the glare from flat surfaces such as water or the road. Light reflected from flat surfaces is generally horizontally polarized. Rather than scattering in all directions (as is more typical) the light reflected from these surfaces travels horizontally, causing a sometimes intense glare that can often be dangerous during certain activities. Polarized lenses contain a special filter that reduces this glare by blocking this intense light. Although many prefer polarized lenses for driving our outdoor activities, there are some instances where polarized lenses are not advisable. Please inform your doctor of what your eye glasses will be used for so that they can ensure you're safety through the type of lenses you are prescribed.
Photochromic Lenses (Transitions) - Photochromic lenses darken when exposed to specific types of light most commonly UV radiation) and, in the absence of these types of light, return to being clear. They way they work is by embedding molecules of silver chloride (or another silver halide) into the lens. These molecules are transparent in visible light (such as indoor lighting). However, when exposed to UV rays, they undergo a chemical process which causes them to change shape and absorb visible light. effectively causing the lenses to darken. This process is reversed when the exposure to UV rays ceases. Since vehicles have UV coatings built into their windows, regular photochromic lenses do not change when exposed to the sun in cars unless they are a specialized version.
