1. What is Anti-Reflection Coating (AR)?

The use of anti-reflective coating (AR coating) on lenses has many benefits. Firstly, AR coating improves visual clarity through the lenses. The use of the coating also significantly reduces strain on the eyes. The benefits of AR coating all stems from its ability to virtually eliminate all glare and reflections from the front and back of the lenses. As a positive result of the lack of glare, an increased amount of light is able to pass through the lenses which optimizes visual acuity. This leads to fewer distractions primarily at night time.

2. What Are The Differences Between Polarized and Non-Polarized Lenses?

Generally, the difference between polarized and non-polarized sunglasses lies in how they impact and protect your eyes when exposed to the sun. Polarized sunglasses are able to reduce the amount of glare and sun haze you will be exposed to while in a sunny environment, while non-polarized sunglasses will not.

Benefit to Polarized Lenses

A valuable benefit polarized lenses offer is almost complete protection against the horizontal glare from the sun, making the suns reflection almost unnoticeable, resulting in a clearer more defined vision. The intensity of the emission of the sun waves is much higher than the scattered ones. Therefore making this kind of light far more harmful for the eyes and especially for those who are driving.

Polarized lenses are used to block the intense light from sun waves reflected off of flat surfaces. The reasoning behind this is that polarized sunglasses are created with vertical polarization, while the light from the sun that is reflected off of flat surfaces is horizontally polarized. Also, various polarized lens colors are made and each of them offer different benefits under various circumstances.

Benefits of Polarized Sunglasses:

• Reduce Glare, Enhance Contrast,  Clarity, Light Sensitivities , Reduce Eyestrain

Benefits of Non-Polarized Sunglasses

Non-polarized lenses have a dark shade which in deed does reduce the intensity of light coming toward the eyes. However unlike polarized lenses, they are not able to counter and protect the wearer from horizontal polarization. Non-polarized lenses are unable to take into account that in which the direction the light is coming from, deeming them less protective than polarized lenses.

Even though polarized lenses improve visibility and are able to provide far better protection from the suns waves, there are some disadvantages. For example, polarized lenses may actually reduce visibility when looking at an image that is being produced by a liquid crystal display (LCD).

If you are one to be constantly under the sun partaking in activities such as jogging, outdoor sports, fishing or any outdoor activities, polarized sunglasses are most definitely the better choice for you when purchasing new sunglasses.

3. The Importance of an Up-To-Date Prescription

The standard duration of validity of a prescription for adults is 2 years and 1 year for children under 18. Also, if you have diabetes, it is recommended that you get your eyes checked once a year.

• Sphere(SPH) indicates the amount of lens power, prescribed to correct nearsightedness (-) or farsightedness(+).
• ADD(for bifocals) is the added magnifying power applied to the bottom part of multifocal lenses to correct presbyopia.
• Cylinder(CYL) indicates the amount of lens power for astigmatism.
• Axisdescribes the positioning of the cylindrical power on your lenses (required for astigmatism).

4. Selecting the Right Frames

When trying to find the right frames, there are a few main factors you should consider when looking for the perfect fit.

Wearing the right frames can not only improve your vision, but can complement your facial features and provide a balance to your overall look. To assist in finding a frame that suits your face, we can categorize the shape of the human face into a few general categories.

Before buying a new pair of glasses and choosing your new frames, consider what your personal and professional needs are. Are you the creative professional? Are you the busy student? Or are you the stylish parent? Strictly business or young hipster? Concluding your style and looking for a frame that embodies and represents that will greatly help you find a frame that fits your personality and look.

Sizing and comfort should be your primary concern when on the hunt for finding a new frame. A frame can look great on your face but if the sizing is off they will be terribly uncomfortable. If you currently own a frame that fit you well, you can check the eyes size measurements printed on the inside arm of the frame. Also in some cases the eye size will be printed behind the nose bridge of the frame. The first number is the eye size which represents the measurements of the horizontal width of the lenses, this measurement ranges generally between 40mm-62mm. The second number following the eye size number is the bridge size. This number ranges generally between 14mm-24mm. The bridge size is the measurement between the two lenses.
