Recommendation

&lt;p&gt;Single power through the whole lens for distance vision and those who don't need reading glasses. This is the most popular option. For those under age 40, single vision is the best option.&nbsp; For those over 40, see our FAQ page on why this may also be the best option for you.&lt;/p&gt;

&lt;p&gt;Corrects for distance and reading only. Nothing in between.&nbsp; Distance is considered 2 feet or more.&nbsp; Reading is considered 6 to 12 inches.&nbsp; With bifocals, you’ll lose that in between range of 12 inches to 2 feet.&lt;/p&gt;

&lt;p&gt;For those that have a prescription for both distance and reading, progressive “bifocals” allow you to see every possible range. There is also no visible line.&nbsp; The downside to progressives is that you have a more limited range of vision in each “zone”. Basic progressives will have less peripheral vision and the transition between each distance of power may be more choppy forcing larger head movements to see objects more clearly.&nbsp; All progressives require measurements. &nbsp;Frames will be sent to you first to get measured and will not come with the prescription lenses installed. You then need to send it back to us with measurements for fulfillment of prescription lenses. &nbsp;&lt;/p&gt;

&lt;p&gt;For those that have a prescription for both distance and reading, progressive “bifocals” allow you to see every possible range. There is also no visible line.&nbsp; The downside to progressives is that you have a more limited range of vision in each “zone”.&nbsp; For sports, we recommend our “Sport” progressive lens.&nbsp; This is the “best” option for sports use.&nbsp; Sport Progressive offer a very wide area for distance vision including the best possible peripheral vision.&nbsp; The areas for intermediate and near are intended more to read a phone or change a flat tire.&nbsp; The zones will be narrower for the 6 inch to 18 inch range.&nbsp; Our “Best” progressives feature HD digital free form technology. Progressives require measurements. &nbsp;Frames will be sent to you first to get measured and will not come with the prescription lenses installed. You then need to send it back to us with measurements for fulfillment of prescription lenses. &nbsp;If you want the best progressive technology but don’t need to maximize distance (for safety eyewear or other more every day use eyewear), please let us know and we can make that switch for you.&nbsp;&lt;/p&gt;

&lt;p&gt;For those that have a prescription for both distance and reading, progressive “bifocals” allow you to see every possible range. There is also no visible line.&nbsp; The downside to progressives is that you have a more limited range of vision in each “zone”.&nbsp; Better progressives you have less blur area on the periphery so you get a wider range of vision.&nbsp; The transition is also smoother meaning less head movements needed to find each “zone”.&nbsp;&nbsp; Our “Better” progressives feature HD digital free form technology.&nbsp; All progressives require measurements. &nbsp;Frames will be sent to you first to get measured and will not come with the prescription lenses installed. You then need to send it back to us with measurements for fulfillment of prescription lenses. &nbsp;&lt;/p&gt;

&lt;p&gt;Digitally (HD) manufactured lenses create a wider field of view in focus as well as less errors and aberrations across the lens. Analogous to HDTV versus standard definition TV. Upgrade can be added to any standard lenses (i.e clear, transitions, etc.)&lt;/p&gt;

&lt;p&gt;Aspheric lenses make thicker prescriptions come out cosmetically nicer by causing less lens edge thickness and reducing magnification appearance of plus lens powers.&lt;/p&gt;

&lt;p&gt;“Lens Thinning” technology is a process developed to minimize the thickness and weight of a prescription lens. Outside the optimal optical area, “Lens Thinning” reduces the thickness with a gradual change in curvature, resulting in a thinner and lighter lens. (note this does mean that the outer edges where this thinning process is done will be blurred out)&nbsp; High prescriptions or lenses for high wrap sport frames often end up being thick and heavy. Thinning of lenses with “Lens Thinning” technology offers the chance of making those lenses that were previously impossible due to their thickness.&nbsp; “Lens Thinning” feature is available with Free Form Digital lenses only, and is only compatible with IC fog coatings.&nbsp; Not available for standard single vision lenses (you must pick &quot;Digital Free Form Single Vision or Progressive lenses in step #1)&lt;/p&gt;

&lt;p&gt;Mirror coating makes lenses a little darker. &nbsp;Color of mirror is purely cosmetic (how it looks from the outside or how people see it on you)&lt;/p&gt;

Impact resistance but better clarity than polycarbonate.
