There are also a number of additional services that an optical lab can offer that will benefit any optometry practice. For eye care providers, being able to offer the best in vision care is crucial to the overall success of the practice and patient base. An optical lab carries out a number of duties that can help lighten the load at the doctor's office, and eliminate the need for storage space for rarely used equipment or optical lense. While the quality of most of the work performed is strictly up to the optometrist and their skill level, there is some work that must be outsourced to an optical lab, and these labs are only as good as the equipment it uses and the technicians that use it. For instance, most doctors will have lenses for most of their patients in-stock.
This allows the doctor to fill the patients prescription, along with any options for the optical lense, in-house. However, there are some occasions when a patient might have a prescription that needs to be specially manufactured, and cannot be filled in-house.Therefore, when it comes to finding the right lab, there should be some extensive research into both its hiring practices and the use of the latest technology because the work of the optical lab reflects the work of the optometrist. It is best to find a lab that manufactures lenses using the most up-to-date equipment. The technology used for creating prescription lenses has changed dramatically, even over the last 10 years. For example, lenses with an anti-reflective coating have become very popular because they are resistant to both glare and scratches.
While anti-reflective coating is a popular choice, there are a few labs that have not caught up to this technology, and it can hurt business if the optometrist cannot offer this option to all of their customers. In fact, there are a few labs that are innovators of lens technology, and offering some of these options might be exclusive to one particular lab, whereas another lab might not be able to offer the same options.

The birds have no real interest in the inside of the house. In fact, it's most likely they can't see the interior. What they do see is the reflection of the outside on the window, the clouds and the reflections of birds. This is simply an extension of the birds world outside.Why would a bird go flying into a window at full speed? Are they attacking the house?It's not what they see inside the window that they are trying to get at. This will happen more often for windows with some type of reflective coatingor solar tinting, but it will still happen with ordinary windows, especially if the interior rooms are dark and it's sunny outside. Most of the solutions to birds crashing into your windows will act to destroy the appearance that the window is an extension of the outside environment. For windows that don't have a reflective coating the window the answer might be as simple as drawing the shades. This will be more effective if the shades have a white backing.The other alternatives involve the outside appearance of the windows, and reducing reflections the birds see there. The most straightforward is to put screens on the problem windows. Putting screens act not only to reduce the reflective coating from the window, but in the case where a bird might still crash into it, the window is cushioned so the birds may not be injured.Screens just won't work on some windows, for example on picture windows, so in those cases some other visual obstruction needs to be used. This is just a large artificial web that can be placed over the window that looks somewhat like a spider web. Since its a web it doesn't block the view like a decal, and birds will naturally tend to avoid a web.
You can create the same effect with simple ribbon or string, creating a simulated web, and this can be done without blocking the view too much. If you are only seeing this problem during a short season each year, you may want to use a simple reflective coating on the window like soap or shoe polish as a short term visual obstruction.Some people will attach decals to the window, but many folks don't care for these from an esthetic standpoint. The lazy man's solution is to simply leave the windows dirty enough that they are no longer reflective.Finally, just move the birds. If you have a birdhouse or bird feeder near the window, it might be best to move it further from the window so the birds will not be so likely to be flying near the window to start with.

Sunglasses have been always known for giving your eyes shade and protecting your vision from the harmful ultra–violets (UV) rays. With the depleting ozone layer, the importance of sunglasses has increased tenfold. Now–a–days, prescription glasses for kids are also available, making sure that taking care of one’s eye health begins early. Not only prevention is better than cure, it is less expensive too. To protect your eyes and vision, prescription glasses and sunglasses have become indispensable tools. Prescription glasses not only can take care of your vision related problems, but can also protect your eyes from other risks.
Almost sunglasses and prescription glasses come with an UV coating. Ultra–violet rays are the primary reason for cataracts and an UV coating greatly reduces the chance of its occurrence. Generally the tint of the lenses of these prescription glasses and sunglasses can automatically adjust to the particular circumstances. When the concentration of UV rays is high, the optical lense become darker and vice–versa, providing your vision complete protection. Various occupational glasses are also available which are specifically designed for your job or hobby. Whether you are a librarian or a mail clerk who routinely need to file and read items overhead or pharmacists who has to spend most of the day reading small prints on the labels, you will find prescription glasses with specially crafted lenses which will help you to complete your job without any eye stress. During a bright day, the glare of the sun can have damaging effects while driving and doing other activities. Prescription glasses or prescription sunglasses with anti–reflective coating reduce this glare, giving you a much clearer vision. Anti–reflective coating can also protect you from UV rays getting reflected off water, sand, glass or cement. As the decreased reflection improves the vision, it increases the focus. This proves beneficial when driving at night or working in front of a computer. The less amount of glare effectively reduces the stress on the eyes and your eyes get less stressed.

The reflective coating is a very thin layer on the surface of the lens; it is designed to be the thickness of a quarter of the wavelength of light - so that when light reflects off the lens, it is half a wavelength out of synchronisation with the reflections from the surface of the coating, and therefore neutralises or offsets the reflections.Anti - Reflection coats stop these reflections and make the spectacles look cosmetically more attractive, but also reduce glare through the lens, and make wearing them easier particularly when night driving and you are sensitive to headlights from oncoming traffic.
Most reflective coating are multilayered so that they cancel out light from all parts of the visual spectrum - however they are never 100% efficient and a small part of the spectrum does not get neutralised - this is why they often have a pale blue/green appearance depending on the constitution of the chemistry used and as a consequence which part of the spectrum is not blocked.The term MAR coating simply refers to multi anti-reflection coating. HMAR refers to MAR with an additional hard coat on top.
The reflective coating can be added after the fact as well - so if you have a favorite pair of spectacles, and find that glare and reflections are affecting you, it is possible to take them on to an options shop and have the coating added later.For general purpose glasses and sunglasses (or tinted glasses), the cost of the anti-reflection probablt doesn't justify its addition - but if you are either susceptible to light - and in particular to rapid changes in light conditions, for example when driving - this can be a wise and safe investment.

A common issue with prescription glasses is 'back-glare' which is the light hitting the rear of the lens and bouncing straight into the eye. Therefore, anti-reflective coating improves the visual quality, preventing 'back-glare', and cosmetic appearance for the wearer.Anti-reflective, or AR, coating is applied to the front and rear surface of the lens to eliminate residual reflections on the lens surfaces. Some anti-reflective coating also has scratch resistance properties as standard to protect your lenses against unwanted scratches. Extensive exposure to the sun's UV rays can cause disorders such as cataracts and muscular degeneration. UV400 Protective reflective coating is a coating applied to the front and rear surface of the lens to eliminate residual reflections on the lens surfaces, and to protect your eyes from the sun's harmful rays. This protective coating is particularly recommended for anyone working outdoors in bright sunlight. Unfortunately no glasses are ever absolutely guaranteed to never have scratches. However, one can have a scratch resistant coating applied to the front and rear surface of the lens to help prevent scratches. This coating will increase the life of your lenses by reducing the wear and tear and by providing you with better vision and improved cosmetic appearance.Super reflective coating is the ultimate four-in-one coating providing the better value for money out of the coatings available. The coating is applied to the front and rear surfaces of the lens, and has anti-reflective properties which eliminate residual reflections on the lens surface that reduce clarity of vision. Super duper coatings come with enhanced scratch resistance and include UV400 protection. This coating has the added advantage of preventing water, dirt and greasy smudges from sticking to your lens surface so keeping them even cleaner.
