Knockaround is an online brand that sells nonprescription sunglasses. A person can choose from one of the company’s ready-made styles, or they can custom-make a pair of eyewear of their own.

This article discusses what Knockaround is, which products are available for purchase, how to order, and how sunglasses promote eye health.

Adam Moyer founded Knockaround in 2005. The company operates from San Diego, CA, and aims to provide original, affordable, and durable sunglasses that are stylish and practical.

Knockaround sells ready-made and customized sunglasses. The company also offers limited-edition sunglasses and collaborates with partners to sell branded and holiday-inspired frames.

Knockaround does not have any reviews on Trustpilot, and it does not have a Better Business Bureau page.

However, the company has a store on Amazon, and purchasers give most of its products a rating of 4 out of 5 stars.

According to positive reviews, the sunglasses are durable and not expensive. Customers also mention that the sunglasses are comfortable to wear and stop them from squinting when in sunlight.

Authors of negative reviews claim that the sunglasses are of similar quality to cheaper options. Some mention the polarized lenses are thin, with others seeing the person’s eyes while wearing them.

One reviewer notes that the lens tint began to peel off after they used their sunglasses for 2 months.

All Knockaround sunglasses are unisex styles.

The company offers 14 different styles, including:

  • classic sunglasses
  • sports sunglasses
  • kids sunglasses
  • snow goggles
  • blue light-blocking sunglasses
  • polarized sunglasses

People can also filter their searches by frame and lens colors and frame styles.

Alternatively, people can customize and design their pair of sunglasses. For example, a person can choose the color of the front and arms of the frame, select the lens color, and decide whether the lens has any protective coatings, such as blue light-blocking filters.

Knockaround also sells various accessories, such as soft glasses cases, tote bags, and some clothing.

The Centers for Disease Control and Prevention (CDC) state that wearing sunglasses reduces the risk of cataracts, damage from UV rays, and sun exposure. Sunglasses that block UVA and UVB rays give a person the best protection.

The CDC notes that most sunglasses for sale in the United States meet this standard. However, people should check what protection a pair of sunglasses offers before making a purchase.

According to the American Academy of Ophthalmology (AAO), long-term exposure to the sun can increase the risk of eye conditions, such as macular degeneration and eye cancer.

Short-term exposure can also lead to photokeratitis, which is sunburn on the front part of the eye.

However, a 2019 study suggests the type of sunglasses a person wears can influence the amount of protection they receive.

The researchers found that wide sunglasses protect eyes from UV rays during the winter, and goggles offer the most protection.

Other factors that can influence the protection level of sunglasses include the time of day, the season, and whether a person looks directly into the sun.

The AAO recommends a person looking to purchase a pair of sunglasses do the following:

  • look for a sticker that says the sunglasses block 99–100% of UVA and UVB rays
  • consider oversized or wraparound sunglasses, as these provide further protection
  • look for amber-, green-, or gray-colored lenses to increase contrast when playing sports
  • consider polarized lenses to reduce glare

Knockaround sunglasses are available to purchase online and in selected stores across the U.S.

People can choose from ready-made sunglasses, but they also can custom-design a pair. The company has various frame and lens options for adults and children.

It is important to wear sunglasses to protect the eyes and the skin around them from sunburn and sun damage. Sunglasses can also help prevent eye conditions, such as cataracts and glaucoma.

People should only purchase sunglasses that block 99–100% of UVA and UVB rays.
