How to Choose Eyeglass Lenses


High-quality lenses and coatings helps enhance vision.

This guide will help you better understand which lens type is fit for you and help you to choose more appropriate lenses and coatings.

Visual Needs

The lenses you choose are primarily determined by the vision-correcting properties.Depending on your visual needs, you may need either single-vision or multi-vision lenses.

For many people, single-vision lenses correct their vision adequately, either for distance or for reading. We recommend you to contact your optometrist to confirm whether you need multi-vision lenses assuredly.

Single-Vision Distance

More than half of people with poor eyesight are looking for single vision distance lenses to correct their vision.

If you have distance-corrective glasses, your prescription will begin with a (-), and your lens will be concave, or curve inward, to correct your vision properly.

Single-Vision Reading

Reading lenses are designed to help you see things at a close distance, typically between 30 and 40 cm.

These lenses are convex, or curve outward, and are appropriate for people with prescriptions beginning with a (+).

Progressive Lenses

Progressive Lenses are unique lenses, designed to seamlessly incorporate distance, middle- and near- vision correction.

Because these lenses are highly personalized, they can correct even the most unique eyes, and provide all the benefits of bifocal lenses without the obvious horizontal line.It is a better choice for people who use both distance and reading glasses, so they do not need to carry around two pairs of glasses wherever they go.

Lens Coating

Coating bring your lenses different attributes, making them behave differently.Please read the following lists to better understand what the coatings available in our online catalog and what they can bring you.

Anti-Scratch Coating

Anti-scratch coating protects your lenses from everyday wear and tear, scratches and abrasions, and helps reinforce them againstdropping.

Anti-Reflective Coating

Anti-reflective, or AR, coating is another beneficial coating for any pair of eyeglasses.This coating gets rid of annoying glare, halos around lights and reflections on your lenses caused by computers and lights.

Anti-reflective coating is especially important for people with high-index lenses, as these lenses have higher refractive indexes.This increased refractive index means these lenses will tend to reflect up to 50 percent more light than traditional lenses, causing more glare unless they are equipped with AR coating.

Anti-reflective lenses are important for nearly everyone in the modern world — especially those working around computers or cameras or regularly driving at night.

Light-Adjusting Coating

This coating will change the tint of your lenses depending on the amount of light they are exposed to, becoming dark outdoors and clearer indoors.This helps protect the wearer’s eyes from harmful UV rays and direct sunlight, protecting the wearer’s vision.

We offer premium Transitions™ lenses, as well as basic Photochromic lenses, both of which are excellent options for those seeking light-adjusting coating for their lenses.

Anyone working in positions where they switch from indoor to outdoor environments frequently will benefit from light-adjusting coating, as well as people who are concerned about their overall eye protection from the sun.Light- adjusting glasses offer the same amount of protection as sunglasses, without requiring you to purchase and carry around an extra set of eyewear.

Color Tint Coating

Many people choose to add a hint of color to their lenses to help them see more fashionable.Besides, these color tint lenses are ideal for people looking to add some more color to their world.

Note: Our color tints cannot be added to polarized or photochromic lenses.

Gradient Tint Coating

Gradient Tint lenses have a dark tint at the top of the lens and then progressively lighten toward the bottom.The resulting lens offers the wearer plenty of sun protection, as well as privacy, but offer you varying degrees of light.

Note: Gradient tints are only applicable to lenses for frames above 36mm in height.

Polarized Coating

This coating reduces the annoying, and sometimes dangerous, reflections on your lenses created by water, roads and other surfaces. STMUSE’s polarized coatings come in standard dark green, dark brown or dark gray tints.

If you drive or bike frequently, and travel along bodies of water or slick roads, you could greatly benefit from polarized coating.

Mirrored Tint Coating

Mirrored lenses are functional and fashionable sunglasses with extra flash.It brings you look a little bit of mystique, or help you to hide your eyes from onlookers.

STMUSE offer various of reflective coating comes in blue, silver, gold and amber, and so on. They look so radiant.

Water-Repellant Coating

Water-repellant coatings keep water droplets, dirt, and smudges off your lenses, which helps to maintain their cleanliness and reduces the need for you to clean them regularly.

If you live in a rainy area, work, or live around water sources, we recommend you choose this lens coating to keep your lenses as clear as possible!

UV Protective Coating

With repeated exposure to the sun over time, UV radiation can damage eyes. By deflecting harmful UV rays from the sun before they can damage your eyes, this invisible UV protective coating works like sunscreen for your eyes.

It is the reason why UV protective coating is so important for everyone.

Digital Screen Protection Coating

In modern society, we nearly spend our every hour on looking at various screens — people check their smartphones every 8 minutes on average, 52 percent of people put in 8 hours to work with a computer, 75 percent of people watch TV for 2 hours. So, eliminate sleeps, our vision always vulnerable to blue light.

To help protect your eyes from damage, we offer digital screen protection coating. Both of these lenses are designed to protect your eyes against the blue-violet light emitted by digital screens, and are also designed to be scratch-resistant, UV-protective, and anti-reflective.

As mentioned above, the biggest source of potential harm from digital screens is blue light, which can be found in just about everything from sunshine to computer screens, can be damaging to our eyes after excessive exposure.That’s why you feel discomfort after using the screens for a long period of time.“Long-term heavy use” — that is, using a screen over 3 hours a day. This can contribute to eye dryness and fatigue, an inability to maintain focus, headaches, and long-term wear on your vision.

Overusing mobile phones is detrimental to physical health for watching mobiles or screens for a long stretch definitely impairs one's eyesight. Especially for kids, they are at greater risk for long-term damage than adults.Health authorities in Britain, France, Germany and Russia have all issued warnings to against allowing small children to use cellphones for extended periods, if at all.

Therefore, for children and adults, they all need Blue blockers lens.
