How To Buy Prescription Lenses

Traditionally, people let the eye doctor or optician choose lenses for them. Would you let a salesman choose a car for you? A television set? A pair of shoes? No! So don't let someone else choose your prescription eyeglasses lenses. Choosing lenses is not rocket science, you just need to learn a few things. The more you learn, the less you will pay. Here are the steps:

  1. Read Your Prescription
  2. Determine your needs, then pick a type
  3. Choose material
  4. Choose model
  5. Choose options
  6. Checkout

Read Your Prescription

Your prescription is not hard to understand. First, does your prescription you have a correction for distance, for reading, or both? If it is distance or reading, then you need single vision lenses. If you have a distance AND reading correction, then you should consider progressive lenses (no-line) or bifocals (with line). These are called multifocals.

Second, look at the sphere number in the prescription, which largely determines the frame material you need. the higher the number, the more you will need a thinner (and more expensive) high index material. More on that below.

Your Needs Determine Your Lens Type

Single vision lenses are less expensive than multifocals. If you have a distance and reading correction in your prescription, you can consider multifocals for their convenience. For example, let's say you drive to the grocery store or drugstore. You need distance vision for driving, and reading vision to read the labels. With multifocals, one pair will do both. Otherwise, you would need two pairs, and then need to switch between them.

Multifocals are more convenient, but they do come with some limitations. Read this article to learn more about the problems with progressive lenses. Most people love their progressives, but it takes time to adapt to them, and some people never adapt.

Choose A Lens Material

Plastic Lenses

Nowadays, almost all lenses are made of plastic. There are four basic material groupings, which correspond to the "Index of Refraction". The higher your prescription, the higher the index is recommended:

  1. Plastic/CR39, Index 1.56
  2. Polycarbonate High Index 1.59
  3. High Index 1.67
  4. Ultra High Index 1.74
  5. Glass

If your sphere is less than 4.00, you can use plastic/CR39. If it is 4.00 to 6.00, then polycarbonate is a good choice; 6.00 to 8.00 means high index 1.67, and over that, the ultra high index 1.74. The higher the index, the lens becomes thinner and more expensive. But you are able to make your own high index lens choice, based on your needs, preferences, and wallet.

Glass Lenses

Historically glass was the only game in town. Nowadays, most people choose some kind of plastic lens for its lower price and lightness. Although heavier and more expensive than plastic, glass lenses have the advantage of exception optical clarity. Glass lenses also resist scratching must more than plastic lenses.

However, the biggest concern about glass is its ability to shatter or break more easily than plastic, which can cause extreme harm to the eye or result in loss of vision. Glass lenses should never be used for active lifestyles or sports; you will commonly see fishermen wearing bifocal and trifocal glass lenses while quietly reading, fishing, or fly-tying.

Choose Lens Model

In any given category of type and material, there is a range of choices representing good, better, and best lenses. A "good" lens will get the job done at a lower price point. A better one may have a known brand name, or it may bundle some additional features. A best lens choice is the best lens available on the market today. We offer a Perfect Lenses Guarantee on everything that we sell, regardless of which model you choose.

Choose Lens Options

Once you have chosen a lens model, you can then add certain options. Options could include stronger coatings with a warrantee, and/or tinting to make custom sunglasses. You could also choose Transitions, a photochromic treatment, which makes the lenses darken outside and become clear again when indoors.


This process may seem difficult, but it becomes very easy with our prescription lenses wizard. Just follow along and at the end of the process you drop your lenses into the shopping cart, and then check out. Most people find a frame on our website, and then add lenses to the frame. However, we also have a replacement lenses service: you can mail a frame to us, and we will install them for you.

How To Use Vision Insurance Benefits

Some people have vision insurance benefits and try very hard to use the benefits. The problem is that the optical stores inflate their prices in order to discount them when you try to use your in-network benefits. The best way to save money is to order glasses online and then use your out-of-network benefits.

Types Of Eyeglasses

There are many types of eyeglasses frames. But we like to classify frame types by the system used by the frame to hold the lenses:

  1. Full Rim
  2. Half Rim
  3. Rimless Frame
  4. Shield Frame

Full-Rim Glasses

Full Rim Glasses: Ray Ban RX2180VFull-rim eyewear has a frame that fully surrounds the lens. They are some of the sturdiest and most reliable eyeglasses frames, making them perfect for people with a tendency to drop things.

Parents should consider getting their kids a pair of full-rim frames because of their durability. Although they may feel a little bit heavier, they are often a popular choice for people with an active lifestyle.

Half-Rim Glasses

Half-rim eyewear have frames without a complete rim structure around the lens. Instead, there is a solid structure overtop of the lens, which can considerably reduce the weight of the frame.

Half Frame Glasses Type, Ray Ban RX8412Half-rim eyeglasses frames are ideal for people who want a lightweight yet trendy pair of eyewear that's comfortable for wearing over long periods of time.

Rimless Glasses

Rimless eyewear have lenses attached at the bridge (the part across your nose) and the hinges that connect to the arms. This frame type is ideal for people who want to minimize people being distracted by bulky or colorful lenses.

Rimless Glasses Type: Oakley WingfoldRimless frames are a popular choice for both men and women. They're also commonly considered for being stylish and worn on special occasions such as weddings and graduations. However, while rimless frames are sleek and reveal more of your face, they also are less sturdy than other frame types.

Shield Frames

Shield frames are a unique style of frames designed to protect against unwanted debris and light in the peripheral areas. Although these frames may seem like a bold fashion statement, they offer substantial protection for your eyes. The frames are typically used for sunglasses, and cannot hold prescription lenses. The only way to use a prescription with this type of frame is to use an "optical insert", which hold prescription lenses behind the shield lens.
