Trifocal glasses are a type of eyewear that correct for three different ranges of vision on one lens. From top to bottom, trifocal lenses correct for distance, intermediate, and up-close vision problems. (Learn More)
Trifocals are typically recommended for people over the age of 40 who have a pre-existing vision condition and are starting to experience presbyopia. But anyone who needs help with the three fields of vision could benefit from trifocal glasses. (Learn More)
Trifocals are made by putting three different vision prescriptions on one lens. First, the distance vision prescription is made on the lens, followed by the intermediate vision prescription for the middle of the lens, and then the near vision prescription on the lower portion of the lens.

Trifocal glasses serve a unique purpose compared to other types of glasses. Regular glasses can only correct for one vision prescription. Bifocals correct for just two fields of vision on a lens. Progressives are similar to trifocals, but they can provide a more seamless transition between vision ranges. (Learn More)
The cost of trifocals compared to other types of eyeglasses varies, depending on the level of customization you are looking for and what special options, like lens coatings and frames, you select. (Learn More)
While trifocals are helpful for people with multiple vision problems, there are downsides to them. Difficulty adjusting to the lenses, a lack of full customizable capacity, and a need to replace lenses as your vision changes are some of the drawbacks. (Learn More)
Trifocals are available at most local and online eyewear retailers. If you already have a vision prescription, you can order a pair right away. Otherwise, start by getting an updated vision assessment from your eye care provider. (Learn More)
What Are Trifocal Glasses?
Trifocal glasses have a special lens that provides vision correction in three different ranges of vision: near, intermediate, and distance. A trifocal lens has lines on it that delineate the corrective area on the lens for each range of vision. Because of these lines, vision can be blurred between each focal range.
The top portion of a trifocal lens corrects for distance vision, for activities such as driving. The middle portion of the lens corrects for intermediate vision, which helps for seeing objects at about an arm’s length away. The lower portion of a trifocal lens is for close activities, such as reading.
Who Are Trifocals Best Suited For?
Trifocals are best suited for people who need vision correction at multiple distances. Certain vision conditions can cause people to need trifocal lenses.
Many people develop presbyopia for example, as they age. It is a common condition that typically starts to occur just past the age of 40 and causes people to lose the ability to see clearly close up.
For people who already have an eyeglass prescription for middle or distance vision problems, the development of presbyopia may lend to a need for trifocals. Presbyopia is part of the normal aging process and can cause people to need to change their eyeglass prescriptions. For people who do not wish to wear contact lenses or undergo eye surgery, trifocal glasses are a great way to allow them to continue seeing clearly in all vision ranges.
How Trifocals Are Made
Trifocals are made by creating three distinct vision prescriptions on one lens. If you are getting customized trifocals, you may be able to select the design of each segment.
The two main types of trifocal options to choose from are:
- Flat-top trifocal lens. The near and intermediate vision segments are fit into a D-shape that allows for good peripheral vision. They don’t reach across the whole lens, and they are easy for people to adjust to.
- Executive trifocal lens. The intermediate segment is thinner with this lens. Each segment runs across the whole lens, and a broader range of corrected vision is offered.
To create a trifocal lens, the distance prescription is made on the entire lens first. Following the distance prescription, additional diopters are added on top of the lens until the intermediate prescription is achieved on the rest of the lens. Finally, more diopters are added to the lower part of the lens until the desired near vision prescription is reached.
Trifocals can be made on the following lens materials:
Trifocal Glasses vs. Other Types of Glasses
Trifocal glasses are unique to other types of glasses due to their ability to provide vision correction in three different fields, all in one pair of glasses. Trifocal glasses, however, are not appropriate for everyone.
Other types of glasses include:
- Standard eyeglasses. Standard eyeglasses are the most common type of corrective eyewear prescribed for many different vision problems. A single vision prescription is made on the lens of regular glasses.
- Bifocals. Bifocals provide vision correction at two different fields of vision rather than three, like trifocals. With bifocals, the top part of the lens is for distance vision, and the bottom part is for up-close vision, with a clear line delineating the two prescriptions.
- Progressives. Progressive lenses provide correction for multiple fields of vision with no distinct line across the lenses. The prescription strength progressively increases from top to bottom.
While increasing numbers of people are choosing progressives over trifocals, trifocals tend to offer a better peripheral field of vision than progressives, especially for reading or working on the computer. Additionally, many people find progressives more functional than bifocals or trifocals, but they can be harder to get used to.
The cost of your eyeglasses will vary depending on how much customization you need, what types of frame and lens coating you prefer, and where you choose to buy your glasses. In general, however, multifocal lenses are more expensive than regular glasses with a single vision prescription.
Reasons that multifocal lenses cost more include:
- Materials. High-definition lenses, which are the most expensive, provide the sharpest vision and most peripheral vision for people with complex eye conditions that require a multifocal lens.
- Design. The design of a trifocal or progressive lens is much more complex than a single vision or bifocal lens, making it more expensive.
- Coatings. Extra cost is added for specialized coatings, such as on adaptive progressive lenses.
- High-end options. If you have specific vision prescription needs, high-end (and more expensive) lenses can be customized to accommodate unique vision requirements.
- Brand name versions. Brand name frames and lenses typically cost more than generic glasses. Similar quality glasses can be found at lower prices from less well-known companies.
If you need multifocal lenses and are concerned about the high cost, remember that there are ways to save, even on customized glasses. While some features should not be skimped on, such as the lens material and design, you can save money elsewhere by selecting less expensive coatings and going with generic frames.
Downsides to Trifocals
While there are many benefits to wearing trifocals, there are also a few disadvantages. One of the most common complaints about trifocals is that they are difficult to get used to. Because of the three distinct vision prescriptions on a trifocal lens, it can feel like images are jumping around as your eye moves from one prescription level to the next.
Another complaint about trifocals is that they appear to be a sign of aging. Because of the three distinct vision prescriptions marked by lines on your lenses, someone looking at you with your glasses on can see that you are wearing trifocal glasses. Because of this, some people prefer progressive lenses for a more youthful look.
Additionally, trifocals aren’t as customizable as progressive lenses. Your vision prescriptions for near, intermediate, and vision distance can be customized, but the lenses typically only come in a couple of standard options.
Finally, trifocal glasses only last as long as your vision prescriptions stay the same. If your vision changes, you might need to get updated prescriptions, which would call for new lenses. Fortunately, replacement lenses are available at affordable prices.
Where to Buy Trifocals
If you already know the vision prescriptions you need, there is a wide variety of online and local retailers selling trifocal glasses. Many online retailers, including Amazon, Walmart, and companies that specialize in selling eyewear have large selections of trifocals for you to choose from.
If you think you need trifocal glasses, the best place to start is by visiting your eye care provider. They can determine your current vision prescriptions and discuss the best lens options for you. If you have vision insurance, you may also confirm your vision benefits and see which retailers accept your plan.
