One square frame. One round frame. Both with a warm lens look. Here are five simple ways to choose between them.
In this guide
Which blue light frame looks right for you?
You do not need a rule book to choose a frame. You need a clear look at the shape and the facts that matter.
Dante and Ember give you two different outlines in our blue light range. Dante is square. Ember is round. The real product photos make that first choice easy to see.
Then take a little more time. Look at the side. Check the size details. Think about the tint. Read the order terms.
Here is a simple way to compare the whole pair, so you know what you want before you add it to your basket.
What the lens research means for your choice
Lens science: what the report needs to show
A transmission test shines light through a lens and measures how much gets through at each wavelength. The result can be plotted as a curve. Low transmission at one wavelength does not tell us the curve everywhere else.
A quoted percentage needs its band and test method. A figure for one wavelength, a selected band and all visible light are three different things. They should not be presented as the same number.
Frame shape, coverage and light entering around the sides can matter to the exposure at the eye. A close-fitting research lens and an open everyday frame do not automatically create the same conditions.
A tint changes the view too. The question is not just how a pair looks from the front, but what it is like to look through it. Product photos help show style. A transmission report answers the optical question.
For Dante and Ember, use the real product photos to choose the shape. For an exact blocking number, the report needs to identify the actual lens or supplier model. The report should identify the lens in the pair you buy.
This is how good product information earns confidence: a clear frame choice, a clear optical test and health claims that match the evidence. Each has its own job.
1. Choose a strong line or a soft curve
Dante has a square front. The lines give it a neat, bold look. If you tend to like square frames, this is a clear place to start.
Ember has a round front. The curve gives it a softer outline. If you like round glasses, take a closer look here first.
Neither shape wins for every person. Your own taste counts. Try to picture each pair with the clothes you wear most. You may know at once which you prefer. If not, keep both open as you check the next details.
Key point: Dante is square. Ember is round.
Why it matters: A clear choice of shape makes the range easier to compare.
The quick science: Frame outline is a style feature, not a clinical test.
2. Look beyond the front photo
A front view gives you the shape. The side views show more of the pair you will wear.
Look at the arms and the bridge. Look at how they meet the front. Open the full set of photos on each product page.
A small card image can miss details that change how you see a frame. A closer look helps you choose on the actual design.
The Dante and Ember images are our original product photos. Tap the one you like to see more. You can compare the same views on each page.
Key point: Look at the arms and bridge too.
Why it matters: The front view cannot tell you every detail.
The quick science: Light can also enter around a frame; research wraparounds are not automatically equivalent to everyday frames. Read the research.
3. Compare the size with a pair you own
Style is only part of the choice. Fit matters too.
Find a pair you already like wearing. Use it as a guide when you read the product sizes. Check the lens, bridge, arms and overall frame details where listed.
Do not assume both models have the same size. Do not guess exact fit from a model’s face. A photo can show a look, but faces and fit differ.
If a size is missing or unclear, ask before you order. That is a simple step that can help you feel much clearer about the pair.
Key point: Use confirmed measurements.
Why it matters: A photo has no reliable scale for judging millimetres.
The quick science: Shape and apparent size alone cannot establish optical performance.
4. Think about the warm lens look
Both product photos show a warm orange lens tint. That colour is part of the style. It also changes the view through the lens.
Keep that in mind if you need exact colours for your work. A warm view and a clear view are different choices.
Do not assume the same colour means the same test result. The exact lens information matters for any filtering claim.
This frame guide helps with shape and style. It does not show that one pair gives better sleep or a greater health benefit than the other.
Key point: Think about the view through the lens.
Why it matters: A warm tint changes how colours look.
The quick science: Filtering changes the mix of light reaching the eye. A photo is not a measured spectrum.
5. Check the complete order
Open the product page for the pair you prefer. Check the exact option, its price and the stock status. Read what is included.
Delivery estimates depend on the selected order and destination. Review the delivery information shown at checkout before you pay.
If anything is unclear, ask us before you order. You should know what is in the basket and what to expect next.
These checks are quick, but they matter. They turn a style choice into a clear order.
Key point: Compare the complete pair and order.
Why it matters: Price, the chosen option, delivery and returns all matter.
The quick science: A trial result for another lens cannot determine what is in your parcel.
Still deciding? Keep it simple.
Go back to the shape. That is the main difference you can see straight away.
Do you want the square line of Dante? Or the round curve of Ember?
Look at the photos once more. Then open the pair you would reach for. Check the details and choose the option you want.
There is no need to force a choice from a tiny ad image. Take a closer look at the real frames on the product pages. Your next pair starts with a shape you like.
