Prescription Lens Types

Choosing the right prescription lens type is essential for clear, comfortable vision throughout your day. Explore single-vision, bifocal, trifocal, progressive, double-segment, and reading lenses to understand how each option supports different viewing distances and visual needs. Whether you need glasses for distance, close-up tasks, computer use, or all-day vision correction, VS Eyewear can help you find the best prescription lenses for your lifestyle.

→ Single Vision Lenses
 

Perfect if you need one prescription power for either distance or near.
 

Use single vision glass lenses if you:

  • Wear glasses all day for clear distance vision
     
  • Need help seeing far away (driving, TV, walking around)
     
  • Need dedicated reading glasses for books, phone, or hobbies

Single vision is the simplest, cleanest option for people who don’t need multiple focal zones.
 

Best for: Everyday distance glasses or dedicated reading glasses.
 

→ Bifocal lenses
 

Need clear vision up close and far away?

Bifocal glass lenses split your prescription into two viewing zones: distance at the top and reading at the bottom. The visible line makes the transition predictable and easy to use.
 

Choose Bifocals if you:

  • Need a dedicated distance zone + a near-reading zone
     
  • Prefer a lens with a clear visible line
     
  • Want simple, reliable multifocal vision without distortion

Best for: Anyone who has used lined bifocals or prefers a traditional multifocal design.
 

→ Trifocal lenses
 

Trifocal glass lenses include three distinct zones: distance, intermediate (computer range), and near. Each power is separated by visible lines, giving you structure and clarity at every range.
 

Choose Trifocals if you:

  • Need distance, computer, and reading correction in one lens
     
  • Prefer the precision of three separated viewing areas
     
  • Want consistent performance without “blurry transitions”

Best for: Wearers familiar with lined multifocals who need sharper intermediate vision, especially for office or workstation use.
 

→ Progressive Lenses
 

Progressive glass lenses give you a seamless transition from distance to intermediate to near—without visible lines.
 

Choose Progressives if you:

  • Want one pair for all distances (far, computer, and reading)
     
  • Prefer a modern, no-line look
     
  • Are comfortable with a short adaptation period

Best for: All-in-one everyday glasses with a clean aesthetic.
 

→ Double Segment Bifocal Lenses
 

At the heart of Double D bifocals is their unique design, resembling the capital letter ‘D’ positioned at both the top and bottom of the lenses. This innovative arrangement is tailored for individuals, especially tradespeople like electricians, mechanics, and plumbers, who frequently work in constrained spaces. The dual bifocal segments enable them to clearly view objects at different distances – both above and below – without the need to tilt their heads, thus offering a seamless visual experience.

Double D bifocals feature an innovative, ergonomic lens design that offers several advantages over traditional bifocal and progressive lens options—particularly for individuals working in precision-driven or physically demanding environments.

A bifocal lens with three separate regions separated by visible lines. The top and bottom regions improve vision of close objects while the middle region improve vision of distant objects. This lens helps reduce neck and eyestrain. The bifocal area is usually 28mm wide.
 

→ Reading Lenses
 

Designed for near vision only, these glass lenses give you crisp focus at arm’s length and closer.

Choose a Reading / Near Vision option if you:

  • Struggle with small print on phones, books, menus, or labels
     
  • Do detailed work with your hands (crafts, tools, hobbies)
     
  • Want a separate pair you can leave by the nightstand or desk

Best for: Anyone who mostly needs help within 12–18 inches.

Frequently asked questions

Have questions? We’re here to help

What are the different types of prescription lenses?

The most common prescription lens types are single vision lenses, bifocal lenses, progressive lenses, reading lenses, computer lenses, prescription sunglasses, photochromic lenses, and specialty lenses such as high-index, polycarbonate, and polarized lenses. The best option depends on your prescription, how you use your glasses, and whether you need eyewear for distance, reading, driving, work, sports, or all-day wear.

What are single vision prescription lenses? 

Single vision lenses correct one field of vision, such as distance, reading, or computer use. They are the most common type of prescription lens and are often used for everyday glasses, prescription sunglasses, and prescription safety glasses.

Are progressive lenses better than bifocals?

Progressive lenses are often preferred by people who want no visible line and need correction for distance, computer, and reading vision. Bifocals can be a good choice for people who want a simpler lens with a clearly defined reading area. The better option depends on your prescription, comfort, and how you use your glasses.

What are high-index prescription lenses?

High-index lenses are thinner and lighter than standard plastic lenses. They are often recommended for stronger prescriptions because they can reduce lens thickness and improve comfort, especially in full-rim or semi-rimless frames.

What are polycarbonate prescription lenses?

Polycarbonate lenses are lightweight and impact resistant, making them a popular choice for sports eyewear, safety glasses, children’s glasses, and active everyday use. They are also naturally UV protective, which makes them a practical option for many prescription glasses.

What are photochromic prescription lenses?

Photochromic lenses darken outdoors in sunlight and become clearer indoors. They are a convenient option for people who want one pair of glasses that can work in both indoor and outdoor settings.

Can I get prescription sunglasses?

Yes. Prescription sunglasses can be made with single vision, bifocal, or progressive lenses. They can also include options such as polarized lenses, mirror coatings, tint colors, and UV protection depending on the frame and lens type.

What are polarized prescription lenses?

Polarized prescription lenses reduce glare from reflective surfaces such as roads, water, snow, and car windshields. They are especially useful for driving, fishing, boating, skiing, and other outdoor activities.

What lens type is best for computer use?

Computer lenses are designed for intermediate viewing distances, such as a monitor or laptop screen. Some people use single vision computer lenses, while others choose progressive lenses with an intermediate zone. Anti-reflective coating is also commonly recommended for screen-heavy use.

Do I need anti-reflective coating on prescription lenses?

Anti-reflective coating helps reduce glare and reflections on the lens surface. It can improve visual comfort for night driving, computer use, and everyday wear, while also making the lenses look clearer in photos and face-to-face conversations.

How do I choose the best prescription lens type!

The best prescription lens type depends on your prescription, frame choice, lifestyle, and how you plan to use the glasses. Single vision lenses are best for one viewing distance, progressives are best for multiple distances, high-index lenses help with stronger prescriptions, and polarized or photochromic lenses are useful for outdoor wear.

What is the difference between bifocal and progressive lenses?

Bifocal lenses have two distinct prescription areas, usually one for distance and one for reading, with a visible line between them. Progressive lenses also correct distance, intermediate, and near vision, but they do it without a visible line, giving the lens a smoother, more modern appearance.
