Frequently Asked Questions

How do I read my prescription?

Eyeglass prescriptions may be written in different ways, though most are either printed or handwritten in horizontal rows. The first row is the prescription for the right eye (OD), and the second row is for the left eye (OS). Within each of these rows are three values: Sphere (SPH), Cylinder (CYL), and Axis. The SPH number corrects for nearsighted [indicated with a minus (-)] or farsighted [indicated with a plus (+)] vision.
The CYL number and AXIS number correct for astigmatism. You may also have another field labeled as ADD which corrects for the reading power used in a bifocal or progressive lens. Lastly, eyeglass prescriptions sometimes include the pupillary distance (PD) measurement, which is the distance between your pupils. PD is needed to determine where the optical center of the lens will be for clear, accurate vision. If your prescription does not include your PD, you can measure it yourself with our guide here.
An eyeglass prescription will usually expire in 1-2 years, depending on which state you received your eye exam.

Can you fill my glasses prescription?

Sure. If you have a prescription for corrective prisms, you can click on the "ADD LENS" box on our website's product purchase page. We need you to fill out or upload your prescription information to help you get the right glasses.

What is my pupillary distance (PD) and how do I get it?

Pupillary distance, or PD, refers to the distance in millimeters between the center of one pupil to the center of the other. Having a correct PD on your vision prescription ensures that you’re looking through the ideal spot in your lenses. The average adult's PD is between 54-74 mm; kids' are between 43-58 mm.
It’s fairly simple to measure your PD— all you need is a mirror and a ruler. Once you have what you need, follow the steps below: Step 1: Stand about 8 inch away from a mirror, hold your ruler in one hand. Look straight ahead into the mirror and position the ruler up against your eyebrows.
Step 2: Starting with the right eye, Close your right eye, then line up the ruler so that 0mm is in the middle your left pupil. Step 3: Look straight ahead again and then open your right eye and close your left eye.
Step 4: Read the mm line that lines up with the centre of your right pupil, this measurement is your PD. Measure your PD 3-4 times at least to ensure it's accurate.

What if I have an astigmatism?

Most people have astigmatism. The most common treatments for astigmatism are eyeglasses or contact lenses. You can turn to an eye doctor who will provide you with a prescription for corrective lenses.
If you have astigmatism, we can get you a pair of glasses to correct it.

Do you offer bifocal or progressive lenses?

Certainly! With regard to bifocal glasses, we provide not only bifocal reading glasses, but also bifocal reading sunglasses. And progressive lenses are also provided for those who have a prescription on multiple viewing distances.

Can I use my contact lens prescription to order glasses?

Definitely not! If you currently wear contact lenses, and are thinking of switching to glasses, you may have assumed that your contact lens prescription would simply carry over to your glasses.
Unfortunately that's not the case; the two prescriptions are different because of the distance the lenses sit from your eyes.

What do the Lens Index numbers mean?

Lens index is a number that describes how thick or thin your lenses are. The higher a lens' index is, the thinner it becomes. Higher prescriptions require higher index lenses, while lower prescriptions require lower index lenses.
High index lenses are thinner, more powerful lenses. They're lightweight and stylish, but are mostly reserved for those with higher vision correction needs. While most prescriptions are compatible with more than one specific index, it's up to you to decide which one fits your personal needs!

How do I get thinner lenses?

If you want thin lenses, the best way to achieve it is to get high index lens material.We have high index plastic 1.67\1.71\1.74 to choose from. You can see it when you add the lens.

What are clear lenses?

“Clear lenses” describes lenses that do not have any kind of prescription associated with them. Glasses with clear lenses might also be called “plano” or “fake” glasses. If you were to set a pair of clear-lensed glasses next to a pair of prescription eyeglasses, you likely would not be able to tell the difference between them unless the prescription lenses were particularly strong.
Clear-lensed glasses can be used as an accessory or as a means of protection. For instance, if you have perfect vision, but you have trouble with glare when driving at night, you would buy glasses with clear lenses and anti-reflective coating to reduce glare.

What are blue light blocking lenses?

Blue light blocking lenses have filters that block or absorb blue light, and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.
Blue-light-blocking filter technology works by either reflecting or absorbing blue light. Lenses with a blue-light-reflecting coating can appear bluish, whereas blue-light-absorbing lenses feature a yellow or amber embedded tint.
Unlike reflective lenses, which can only block around 10% of blue light, most blue-light-absorbing lenses (the ones that look yellow or amber) filter at least 35% of blue light. The more blue light a lens blocks, the more orange it appears. Some lenses block up to 98% of blue light, but they can turn your entire world reddish-brown like a sepia-toned print.

What are photochromic lenses?

Photochromic lenses are lenses that stay transparent indoors, but darken when exposed to ultraviolet light from the sun. Essentially, they provide the benefits of glasses and sunglasses in a single frame.
They also go by many other names, including light-adaptive lenses, variable tint lenses, light intelligent lenses, and even “reactolights.” When we’re not using their scientific name, we prefer the term light-responsive lenses, because it neatly encapsulates exactly what these lenses do: they respond automatically to UV light.
If you can’t remember these terms, though, “lens that changes in the sun” usually gets the point across.

What are Polarized sunglasses lenses?

Polarized sunglasses lenses are treated with a chemical that filters out light. However, the filter is applied vertically, so vertical light can pass through, but horizontal light cannot.
Think of it this way: imagine a picket fence with an inch between each slat. You could easily slide a popsicle stick between the slats if you hold it vertically. But if you turn the popsicle stick sideways so it’s horizontal, it can’t fit between the slats of the fence.
That is the general idea behind polarized sunglasses lenses. Some vertical light can pass through the filter, but horizontal light, or glare, is unable to make it through.

What frame style is best for my face shape?

Once you determine your face's shape, you'll want to decide which frame complements it the best. Here are the best fits for each type:
Round face: Aim for rectangular frames with bold angular lines. In turn, these can make your features look sharper.
Oval face: Oval faces are more versatile. Wide frames with a strong bridge enhance your facial features.
Heart-shaped face: Find frames that toe the line between balancing a narrow chin and a larger forehead for a more symmetrical look. Frames with bottom-heavy lines and are slightly wider than your forehead will also help you achieve this.
Square face: Rounder frames soften the angles of the face. If paired with a lens that is slightly wider than your cheekbones, you'll create more symmetry in the face.
Diamond face: Cat-eye and oval eyeglasses enhance your cheekbones.
Of course, these are just our suggestions.

What frame material is right for me?

Choosing the optimal frame material depends on your desired features.
The following categories are provided in EFE for your choice:
Plastics (Acetate, TR90, Polycarbonate, Cellulose Propionate, Other Plastic)
Metals (Titanium, Stainless Steel, Other Metals)
Mixed Materials (Acetate & Metals, TR & Metals, Polycarbonate & Metals, Cellulose Propionate & Metals)

Full-rim, half-rim, or rimless?

Full-rim glasses, especially in the nerd-chic look, are very popular. They are generally more durable than half-rim or rimless frames.
Half-rim frames are great for people with slim faces. They show more of your face than full-rim frames, and are more durable than rimless glasses.
Rimless glasses are great for people who will treat their glasses delicately, and who want their glasses to be practically invisible on their face.

What can I do if my frames don't fit perfectly?

New glasses often need minor tweaks to fit your face right. It’s best to have an optician fine-tune the glasses for you.

How do I determine what reading glasses power I need?

Here are the steps to help you find the right reading glasses power:
1.The most accurate way to determine your reading glasses power is by visiting an optometrist. They can conduct a comprehensive eye examination to assess your vision and provide a precise prescription.
2.If you already have a prescription for reading glasses, you can use that information.
3.You can also use an online reading glasses test to help determine your reading glasses power.

How do I order single vision reading glasses?

Ordering reading glasses through EFE is easy! Once you have selected a frame, click “Add Lens” and follow the below steps:
1. First, indicate that you would like reading glasses by selecting “Single vision” from the Prescription Type drop-down.
2. Next, you’ll need to input a Near Single or Dual PD (pupillary distance) under the Pupillary Distance dropdown. For a Single PD, if you were only given one PD measurement, it is most likely for distance so you will need to subtract 3 to calculate your near single PD. If you were given a dual PD, two numbers - one for the right and left eye, you’ll need to subtract 1.5mm from each number to calculate the near dual PD. Ex. If given PD= 63mm then Near PD= 60mm.
3. The last step is to enter the reading prescription for the right eye and left eye. If your doctor didn’t write out a separate reading prescription then you’ll need to calculate it yourself. You can do this by adding the ADD value to the SPH value and keeping the remaining values the same, as in the example below:

Can I order bifocals that are computer distance on top and reading on bottom?

You bet you can! Divide the NV-ADD in half. Add one of the halves to your SPHs. Leave the other half in the NV-ADD. This creates computer vision in the top of your lens, and reading vision in the bottom!
