The Zenni Optical website says that these lenses can help protect people from blue light while they work on computer screens. Blokz incorporates the blue-light-blocking polymer into the lens so it does not wear away over time.

There are three types of Blokz blue light lenses:

  • Blokz: These offer all-day protection and are the brand’s original lenses.
  • Blokz Plus: This range of Blokz lenses has a mild yellow tint and the brand claims it offers 12 times more protection than its original lenses. The company designed them for people who spend a lot of time using digital screens.
  • Blokz Anti-Fatigue: These Blokz lenses are the same as Blokz Plus lenses, but they add magnification to prevent eyestrain.

People can customize almost any Zenni Optical frame with Blokz lenses.

Kid’s glasses

  • Price range: $6.95–45.95
  • Number of frames: 274

Zenni carries over 200 different styles suitable for children. This includes prescription and nonprescription glasses, and sunglasses.

Many kid’s frames come in bright colors and patterns.

Some models are protective goggles suitable for sports. They feature an elastic strap attached to the stems to secure the glasses. Zenni claims these goggles meet or exceed ASTM F803-19 standards for a range of sports. The F803 standard is the strictest and means they are safe to use during high-impact sports such as basketball, baseball, and soccer, among many other sports.

Clip-On Sets

  • Price range: $19.95–49.95
  • Number of styles: 62

If a person does not wish to purchase separate sunglasses, they may also purchase clip-on tinted lenses. These lenses attach to the front of a person’s glasses. Zenni cuts each clip-on to fit a person’s frame.

Brown, black, and mirror tints are available in certain styles.

Other types of clip-on lenses include 3D movie and driving lenses. As 3D glasses that movie theaters provide will not accommodate a person’s prescription lenses, people will often have to wear two pairs of glasses to watch a 3D movie. Zenni’s 3D movie clip-on lenses means people can easily watch 3D movies using their usual glasses.

Zenni’s driving glasses feature a yellow tint to help with nighttime visibility.

Zenni says clip-on tinted lenses are available with almost any frame.

Sports glasses

  • Number of frames: 46

Zenni carries over 40 different frames specifically designed for sports, such as golf, cycling, and strength training. Other glasses are called goggles and have ASTM ratings classing the glasses as suitable for high impact sports such as basketball, soccer, and baseball.

However, Zenni does not list the ASTM rating for every lens.

Options include sunglasses, protective glasses, and more standard lenses. Certain styles come with tinted lenses, and a person should check whether they can order alternative lenses, such as mirrored lenses, for their chosen frame.

Protective goggles and glasses

  • Price range: $6.95–49.95

  • Prescription protective glasses: These glasses are for general-purpose protection against dust, pollen, and other particles. Zenni recommends them for light DIY projects. The glasses come with snap-on protective shields in clear, pink, green, and blue.
  • Protective Sports Goggles: These sports goggles meet or exceed the ASTM F803-19 standards for basketball, soccer, badminton, and handball. People can buy small, medium, and large frames. The small is suitable for children ages 7–11 or adolescents and adults with narrower faces. The medium is for people ages 12 and over. the large is for adults with larger faces.
  • Non-Prescription Protective Goggles: These are general-purpose glasses for low impact activities. The lenses cover a wide area and shield the top and sides of the face. Some models come with a strap to secure the goggles onto the head.

Bifocals

  • Price range: $6.95–49.95
  • Number of frames: 1,346

  • Number of frames: 1,346

Progressive lenses do not feature a dividing line between the different magnification areas. They can have up to three different “viewing areas”. For lenses using three viewing areas, the top area of the glasses would be suitable for driving, the middle for working, and the lower portion for reading.

What to look for in vision products

The list below describes some characteristics to review and be aware of when purchasing glasses or other vision products:

  • Look for lenses made of materials suitable for the glasses’ intended purpose, such as using a computer or playing sports.
  • Choose protective coatings that are appropriate for the glasses’ intended purpose.
  • Work with eye care professionals or follow online instructions carefully to secure a good fit.
  • More expensive or designer frames will not necessarily mean a better pair of glasses.
  • Look for high quality lenses.

Visual health

One of the best ways to protect one’s eye and visual health is to have regular screenings, including dilated eye exams.

Dilated eye exams can reveal the presence of eye disease and show whether or not someone may need glasses or contact lenses. If a vision device is necessary, a refraction test will follow.

Both optometrists and ophthalmologists can write prescriptions for glasses. A glasses prescription details:

  • the lenses needed for each eye
  • how powerful the lenses need to be
  • if the eye has astigmatism, or a curve to the cornea, that needs correction and where it is
  • whether or not correction for double vision is necessary

An optician can make glasses but cannot write the prescription for the lenses.

Aside from getting and wearing glasses if they are needed, some other tips for protecting eye and visual health include the following:

  • being aware of one’s family history and risk factors
  • resting the eyes regularly when using a computer 
  • wearing eye protection, such as sunglasses, when necessary
  • following a balanced, nutritious diet
  • exercising regularly
  • maintaining a moderate weight
  • not smoking
