Cyxus is an online eyewear retailer that sells blue light-filtering glasses, sunglasses, and prescription glasses.

This article explores the Cyxus brand and reputation, what the company offers, and information on its shipping, returns, and warranty policies. It also looks at other vision products, health, and some alternative brands.

In business since 2009, Cyxus says it aims to combine fashion and function, as it wants people to feel stylish while providing appropriate eye care.

The company claims it has certifications with the following organizations:

In addition, Cyxus has Restriction of the Use of certain Hazardous Substances in Electrical and Electronic Equipment certification. All of these certifications indicate the brand’s adherence to environmental, ethical, and safety standards.

Reputation and reviews

Cyxus has an average customer rating of 4.2 out of 5 stars on Trustpilot, based on 16 reviews. Of them, 87% are positive and mention good quality products. However, 13% of the reviews are less favorable, citing customer dissatisfaction with shipping times.

The Better Business Bureau (BBB) provides the company with a “B” rating but does not give them accreditation. The brand has closed four complaints on this review platform in the last 4 years. While complaint details are limited, they mention problems with delivery and products or services.

Cyxus sells blue light-blocking glasses, sunglasses, and prescription glasses.

Blue light-blocking glasses

The Cyxus range of blue light-blocking glasses feature a non-tinted high energy visible (HEV)-absorb lens, meaning their lenses are virtually clear. The company reportedly builds the product’s blue light-blocking capability into the frames, so it will not wear away over time.

Cyxus offers both adult and child ranges of blue light-blocking glasses, which can be prescription, nonprescription, or reading lenses. The brand has many color and pattern options available, and a person can filter search results to find their desired frame material, shape, and rim. The company also offers spring hinges, ultra-lightweight options, and clip-on styles.

In addition to blue light glasses, Cyxus has a range of sleep glasses it recommends a person should wear in the evening to block out blue light that could negatively affect the sleep cycle.

The prices for Cyxus blue light-blocking glasses range from around $13–119.

The company has many different styles, colors, and frames to choose from, which reportedly offer:

  • 100% UV400 protection
  • Tri-Acetate Cellulose lens material for added visual clarity
  • scratch-resistant lenses
  • shatterproof and impact resistant

Their sunglasses prices range from around $10–80.

Prescription lenses

The company also provides prescription lens options in regular eyeglasses and sunglasses frames.

A person purchasing prescription lenses may also add blue light-blocking as an optional extra.

When placing an order, Cyxus asks individuals to enter their prescription details. It also requires a pupillary distance measurement but provides a guide on how to measure this.

The company claims it requires up to 2 days to process nonprescription orders and 3 days to process prescription orders. Cyxus also offers free standard shipping within all 50 states and many international countries for orders over $16. Amazon fulfills the orders within most countries.

Cyxus has a 14-day returns policy for items that are defective or damaged on arrival. It also mentions if a person accidentally damages their glasses within this 14-day period, it will offer them the same pair for half the price.

If an individual is unhappy with their nonprescription glasses, they can exchange them for a different style or return them for a partial refund.

As prescription glasses are custom, Cyxus does not offer refunds unless there is an issue with their quality.

Cyxus specializes in blue light-blocking glasses, which a person may use when working with digital screens, such as computers. Manufacturers claim these glasses may help prevent digital eye strain. However, the American Academy of Ophthalmology (AAO) states there is no scientific research proving blue light from computers and other digital screens causes any form of eye disease. Therefore, the AAO does not recommend using blue light-blocking glasses.

The organization also advises there is evidence blue light can affect a person’s sleep cycle, and a 2019 study shows that individuals with insomnia may benefit from blocking their exposure to blue light.

According to the Centers for Disease Control and Prevention (CDC), blue light has the strongest impact on a person’s sleep cycle and can cause difficulties falling or staying asleep. Research from 2016 shows some positive outcomes in blue light-blocking glasses for people with delayed sleep phase disorder.

There are a few things to consider when purchasing a vision product. These may include:

  • Trying on the glasses: A person may want to try the product on before purchasing. They may wish to visit a physical store or use a company’s online virtual “try-on” feature.
  • Value and cost: Individuals may consider their budget and decide if the price is reasonable for the personal benefits they will gain and the product’s build quality.
  • Brand reputation: Reading reviews of the brand or retailer can help ensure a person is buying from a legitimate company.
  • Returns, exchanges, warranty: People may wish to consider a company’s returns and exchange policy, particularly if they cannot try a product beforehand. They also may check if there is a warranty policy.
  • Lens options: Sometimes, an individual may need thicker lenses if they have a stronger prescription. Not all retailers offer this option, so it may be helpful to check this in advance. They may also wish to purchase lenses with additional features such as blue light blockers or anti-scratch coatings.

According to the National Eye Institute (NEI), more than 150 million Americans have a refractive error, such as longsightedness or shortsightedness, making it the most common vision problem. The causes of refractive errors may be eyeball length, cornea shape, or lens aging.

Eye doctors can check a person’s eyes for refractive errors and offer a prescription for eyeglasses or contact lenses that will usually correct these vision issues.

The NEI recommends the following steps to help maintain vision health:

  • Speak with an eye doctor for a regular eye exam. According to the American Optometric Association, the recommended eye exam frequency differs by age, risk factor, and family history.
  • Consult with an eye doctor if a person’s vision deteriorates.
  • Speak with an eye doctor if glasses or contact lenses do not help correct vision issues.
  • Encourage family members to have regular eye exams.

A person might consider some alternative eyewear brands, including:

Cyxus is a brand that trades online and sells blue light-blocking glasses, sunglasses, and prescription glasses.

Other companies also specialize in blue light-blocking lenses. A person may wish to consider a variety of factors, such as warranty length and brand reputation, to decide which may be right for them.
