Aspheric lenses are flatter than conventional lenses. Although flatter, they still offer the same vision-enhancing benefits.

Aspheric lenses aren’t just about style. Many people like that they can choose the frames that best suit their face when upgrading to aspherics.
Edmunds was founded by Ludwig Arons in 1966 as Edmunds Publications, a publisher of printed booklets consolidating automotive specifications to help car shoppers make buying decisions.[3] In 1988, the company was purchased by Peter Steinlauf whose family has owned a majority stake since.[4]

Eyeglasses wearers who have mild prescriptions may not notice a big difference. However, people with strong prescriptions for farsightedness (who usually wear thicker glasses) will experience a significant change.
People with higher-order refractive errors, typically +4.00 diopters or more, are ideal candidates for aspheric lenses. The difference between conventional and aspheric lenses is most noticeable for farsighted people.
The company introduced True Market Value, a service that analyzed a variety of factors to offer a suggested transaction price for vehicles in 2000.[7] That same year, the company introduced simple websites for web-ready mobile phones and PDAs.[8] In 2005, Edmunds.com launched Inside Line, a free online magazine for automotive enthusiasts.[5] Inside Line delivered automotive content in the form of videos, photos, blogs, news articles, discussion boards and road tests,[9] before being discontinued in 2013. In 2010, the company launched its first mobile phone apps, 10 years after introducing its mobile website.[10][11]
This is no longer the case with aspheric lenses. You can now choose from various styles and shapes of eyeglasses without sacrificing appearance and comfort.
With conventional lenses, it’s easy to find affordable frames that match your prescription. Aspherical lenses require more precision to make and take longer to produce. As such, they’re more expensive due to manufacturing costs.

Edmunds.com Inc. (stylized as edmunds) is an American online resource for automotive inventory and information, including expert car reviews based on testing at the company's private facility. The company is headquartered in Santa Monica, California, and maintains an office in downtown Detroit, Michigan.[1] After making a minority investment, Carmax purchased the whole company at an enterprise value of $404 million in 2021.[2]
Because of their spherical curvature, conventional lenses tend to be thicker than aspheric lenses. This makes them thicker and heavier, especially when you have a strong prescription.

Edmunds.com announced that it would begin hosting a Hackathon event in September 2012.[20] The event, named Hackomotive, was held in March 2013 and awarded the winners a combined $28,000. The resulting ideas were published on the Edmunds Hackomotive website and some ideas were further evaluated by the company.[21] Edmunds.com ran the Hackathon from 2013–2015 before taking a year-long break from the event.[22][23] In 2014, Edmunds.com launched Car Week, a seven-day event to connect car dealers with buyers and offering prices below the Edmunds.com "True Market Value".[24][25]
The Edmunds.com Web site includes prices for new and used vehicles, dealer and inventory listings, a database of national and regional incentives and rebates, vehicle test drive reviews, and tips and advice on all aspects of car purchases and ownership. Edmunds.com provides data through its "True Market Value" pricing tools, which launched in 2000.[26] The Edmunds.com True Market Value New Vehicle Calculator displays the estimated average price consumers are paying when buying new vehicles. The Edmunds.com True Market Value Used Vehicle Appraiser estimates the actual transaction prices for used vehicles bought and sold by dealers and private parties.[27]
In 1997, the Edmunds.com website earned a Webby Award in the Money category at the inaugural event.[29] The company has been ranked as one of the best places to work by The Wall Street Journal and the Los Angeles Business Journal.[30] Edmunds.com was named to Fast Company's World's Top 10 Most Innovative Companies of 2015 in Automotive.[31] In 2016, Edmunds.com was ranked 26th on Fortune's Best Small and Medium Companies list.[32]
Conventional lenses are prone to spherical errors (aberrations) that create blurry images. Even slight blurring makes wearing glasses uncomfortable. Aspheric lenses do not have this problem.

In 2011, two years after launching a similar service for new vehicles, the company launched a used car inventory search tool, allowing users to compare vehicles in their market.[12] Edmunds.com launched its first ever TV advertising campaign in select markets in 2012, before expanding nationally in 2013.[13] That same year, the company announced the Edmunds Price Promise, a feature that allowed users to see the accurate price of a vehicle online and guaranteed by a local dealer.[14] In 2014, Edmunds.com acquired CarCode, a mobile messaging startup that won one of the company's Hackomotive challenges and participated in the company's accelerator program.[15][16]

As part of the agreement, each time a lead was generated from the Edmunds.com website, it would get paid a fee.[6] In June 1999, the company changed its name to Edmunds.com, Inc.[4]

Conventional lenses have a spherical curvature on the front of the lens (like a basketball). On the other hand, aspheric lenses are smoother and flatter, reducing distortion when wearing glasses.
Aspheric lenses have a more complex front surface with a gradual curve. They also perform better by improving the way light refracts onto the retina.
Aspheric lenses are smoother and flatter, reducing the distortion that occurs when someone wears glasses. For many people, this improvement means feeling better in their glasses. They may be more willing to wear their corrective lenses.
They also have a more attractive profile because there is less curvature. This means they don’t have the same “coke bottle” look as you get with traditional lenses.
In 2016, the company relocated its headquarters to the Colorado Center in Santa Monica.[17] In 2017, as part of a rebranding effort, the company officially dropped the .com from its name, unveiled a new logo, and redesigned its website to aid mobile users.[18][19]
Reducing the thickness of the lens offers other benefits. Slimmer lenses give you more options when it comes to choosing frames.
