How To Buy Prescription Lenses

Traditionally, people let the eye doctor or optician choose prescription 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 a prescription lens is not rocket science, you just need to learn a few things. The more you learn, the less you will pay.

Of course, we offer the best progressive lens on the market today, and you can order these as polycarbonate lenses or high index.

Read Your Prescription

Glasses PrescriptionsYour glasses prescription is designed as an aid for vision correction. It is not hard to understand. First, does your prescription you have a correction for distance, for reading, or both? If your glasses prescription 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.

Finally, be sure that your prescription includes a pupillary distance measurement. Your pupillary distance is the distance between the pupils of your left eye and right eye, and it is required in order to make a complete pair of new glasses. Especially on a new prescription for a complete pair - even if you have used virtual try on technology - the pupillary distance measurement is required. Is this your first frame or a new pair? Just ask you doctor for the full prescription and write the PD down on it if he/she/they do not.

Your Needs Determine Your Lens Type

Single vision lenses are less expensive than progressive lenses or bifocal lenses. Buying prescription eyeglasses online is not difficult. If you have a distance and reading correction in your prescription, you can consider progressive lenses 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.Progressive Lenses

Prescription glasses with multifocal lenses 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 this kind of prescription lens, and some people never adapt.

Choose A Lens Material

Prescription Lenses Material

Plastic Lenses

There are several type of lens materials that you can choose. Nowadays, almost all prescription rx glasses have plastic lenses. 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 Index 1.59

  3. High Index 1.67

  4. High Index 1.74

  5. Glass

Best Prescription Lenses BrandsIf 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 is one of the few online dealers that offers glass lenses.  Historically it 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. They also resist scratching must more than plastic lenses.

However, the biggest concern 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 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 lens coatings and options. Options could include stronger coatings with a warrantee, blue light treatment, and/or tinting to make custom sunglasses. The most popular option is anti glare glasses, aka "AR glasses", which have an anti reflective coating on the lenses.  Anti reflective coatings are very important and highly recommended for all glasses. More recently, blue light blocking glasses have become popular. Blue light blocking lenses can be created by adding a blue light coating to most lenses. Blue light lenses are designed to block harmful blue light, but harmful blue light is more hype than reality, so read our blog article about blue light blocking glasses

Lenses With Glare Are Cloudy

Non-Rx glasses frames are also a choice for some people that are looking to add to their persona but do not need Rx glasses. Prescription glasses starting without a prescription are actually more popular than you might think. Look at all the movies with movie star characters that wear non prescription glasses.

Prescription Sunglasses

Another popular lens choice for lenses is tinting for prescription sunglasses. It could be full tinting for high light activities, or you could also choose Transitions, a photochromic treatment, which makes the lenses darken outside and become clear again when indoors.  

Of course, you can always shop for non prescription sunglasses. Many people like to use their contact lenses underneath designer frames with custom tinted lenses that are actually non prescription glasses. Either way, sunglasses are a great way to encourage and preserve good eye health by providing UV protection against harmful UV rays of the sun.


This process is much easier than you may think, 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 eyeglasses online and then use your out-of-network benefits.Vision Insurance Providers

Categories Of Glasses

There are many categories of eyeglasses frames. Most people like to begin their search by gender, and look for mens or womens glasses.  If you have more specific tastes, you may be looking for the most popular glasses.   Many people prefer flexible glasses that have a change of withstanding an attack of buttocks.  Or, something more trendy like round glasses, or retro glasses.  If you are looking for computer glasses, you should read our article on computer glasses first.

Face Shapes

We are often asked about the right shape of rx glasses for a particular face shape. In general, eyeglass shape either balances or accentuates your facial features. For example, square faces or heart shaped faces wearing round eyewear helps to provide balance. But the round shape is different and can work for round faces. The round shape brings in very powerful cultural implications - the first impression is one of intelligence and self-confidence, and the relationship to face shape is minor compared to that. That explains the Steve Jobs and Harry Potter glasses choices, because they are both intelligent and visionary mavericks.Gucci Glasses

Most Popular Brands

The most popular brands vary, but the two most popular brands, Oakley and Ray Ban, have been at the top since their eyeglasses lines were launched. Following them come Silhouette, which is known for its hingeless, rimless titanium frames - super light and comfortable to wear. Next comes the iconic brand Gucci, closely followed by Tom Ford which has been rising steadily since the brand was born. People often ask for "John Lennon ", "Harry Potter", or "Circle" glasses, and what they are really looking for is perfectly round frames. The top tier is rounded out by Dolomiti Eyewear, which offers a classic design, handmade in Italy, without the designer price point.

After these, come the long-standing favorites of Versace (bold and stylized), Nike (sporty, light, and durable) , and Kate Spade (colorful and trendy). Burberry, Prada, Coach, and Michael Kors round out the top 15 brands that people are always buying.

How to Use Your Vision Insurance BenefitsEyemed

Insurance providers for glasses brands range from supplemental plans offered by your employer, to independent plans that you can purchase outside of your employer's plan. In most cases, you can get your eye exam in- network, and your insurance provider will offer an out of network benefit. Once you have confirmed your insurance eligibility, you can submit the claim form directly to your insurance provider. To obtain insurance benefits after your eye exam, there will be a valid prescription required, your birth date, and a valid zip code required. Unfortunately, when you try to use your vision insurance at most optical stores, you will never have zero hidden fees, because prescription eyewear is how they make their profit.

Getting an annual eye exam is important for anyone, but especialy for people with visual impairment, tunnel vision, a vision impaired profile, eye care needs, and for blind users.  You can find a stylish frame with Rx lenses and your favorite lens coating online, and you can order a frame with nose pads or a saddle bridge.  All of the essential elements are here except contact lens supplies.  Check out a consumer report before you visit an eye doctor.   VSP Vision Insurance
