What Type of Lens Should Be in Your Glasses?

If you’re thinking about new glasses, you’re probably thinking about frames. Choosing the style of frame is an important part of choosing glasses, but which lens you put in those frames shouldn’t be an afterthought. The right lens can help you see better and can be customized to fit your prescription and your lifestyle. 

Lens Materials

Glasses have evolved from being, well, glass into high-tech options for every eye. Most lenses are now made out of plastic or polycarbonate that is more durable and lighter weight. These modern lenses make glasses more comfortable and fashionable for every prescription.

Polycarbonate is an extremely lightweight and durable lens material. It is more durable than glass and plastic lenses and is even used on the windshields of spacecraft. Polycarbonate lenses have the added benefits of providing 100% UV protection and are scratch-resistant. 

Lenses made from polycarbonate are a great option for kids or for anyone who is tough on their glasses. Polycarbonate lenses are also a good choice if you like to look of rimless glasses, due to their impact resistance.  


High-index lenses are another option for your lens material. They are a lighter and thinner material option, making them more comfortable and more attractive, especially for stronger prescriptions.

If you have a strong prescription, high-index lenses will be more comfortable and less bulky than traditional lenses. High-index lenses also help eliminate the magnifying effect sometimes caused by high prescriptions because they allow the lens to be thinner and flatter while still correcting your vision.

Lens Types

Vision doesn’t fit into two categories, so your lenses shouldn’t either. There are varied eye types that aren’t simply nearsighted or farsighted and there are different lens types to match. If you have a complex prescription, there are lens types available that will correct your vision and keep you seeing clearly at every distance. 


Aspheric lenses are flatter than conventional spheric lenses, creating a dramatically slimmer lens. They have the added benefits of fitting closer to the face and creating a better field of view by improving peripheral vision.  

Especially if you have a strong prescription, aspheric lenses can improve your vision and the appearance of your glasses. Aspheric lenses reduce the magnification effect commonly associated with glasses with a strong correction. 


Bifocals are the most common multifocal lens and they contain two prescriptions. In a bifocal lens, the upper half of the lens corrects your distance vision and the lower half corrects your near vision. Bifocal lenses are often prescribed as you age to correct presbyopia and to help you see clearly whether you’re reading or driving. 

Trifocals are similar to bifocals, except they contain three prescriptions instead of two. The third prescription helps improve your mid-range vision, allowing you to see objects within an arm’s reach, like computer screens, better.


Progressive lenses work similarly to trifocal lenses in that they contain three prescriptions, but instead of having different sections for different prescriptions the lens fades gradually from distance vision to near vision. Also known as no-line multifocal lenses, progressive lenses look the same as single-vision lenses. They help you see clearly at all distances without the telltale “bifocal” lines.

Glasses with progressive lenses work well for those who have a complex prescription but don’t like the look of multifocal lenses. Progressive lenses reduce the ageing effect of multifocal lenses without compromising your vision. We carry progressive lenses from Zeiss, one of the most well-known lens companies in the world. If you have presbyopia or a complex prescription, Zeiss progressive lenses are a great option for you.

Lens Finishes

There is a huge variety of lens options available to customize your glasses beyond your prescription. Different lens options can help improve your vision no matter what life throws at you and can even provide a performance edge. There are lens options for every lifestyle, whether you spend most of your time in front of a computer, you’re outside a lot, or a mix of both. 

Blue Light

Blue light is a short-wave, high energy light wave that is emitted by many digital devices like computers, tablets, and phones. Our eyes do not naturally block blue light very well, making blue light a source of various vision problems. 

Blue light can cause digital eye strain, insomnia, and even macular degeneration over time. If you’re suffering from any of these issues, blue light filtering glasses can be especially beneficial. Blue light filtering lenses can reduce the effects of screen time and irritation caused by blue light. We’re happy to help you chose the right blue light lens for your eyes. We also carry a variety of specialty lenses from Zeiss that are custom-made to ease digital eye strain caused by digital devices and time spent in front of a computer


Anti-glare or anti-reflective lenses can improve the look and feel of almost every pair of glasses. Lenses with an anti-glare coating help improve contrast and clarity to help you see better, making them great for driving and night vision. They also help reduce halo effect and other reflections to help improve your vision.

Anti-glare lenses also improve the look of your glasses by reducing glare. No glare means people will be able to see your eyes behind your glasses more clearly, both in real life and in photographs. 


Photochromic lenses adapt based on the lighting of the environment you’re in. Depending on the level of UV and HEV light, photochromic lenses will adjust from clear to tinted. This means you get clear lenses when you’re inside and tinted sunglass lenses when you’re outside without having to switch frames. 

Photochromic lenses can eliminate the need for sunglasses, making them a great choice for anyone who moves from inside to outside often or anyone who appreciates the convenience of not having to switch from glasses to sunglasses. 


Polarized lenses are a type of sunglass lens that come with a multitude of benefits. A special chemical is applied to the lens which blocks certain light molecules from passing through. As a result, your vision will be crisper and clearer. 

Sunglasses with polarized lenses provide clearer vision with enhanced details and better colour vision. They’re recommended for anyone who spends a lot of time outside, especially in harsh light conditions on or near bodies of water. Polarized lenses reduce glare and eye strain, making time in the sun more comfortable. We offer polarized lenses from Maui Jim, a brand known for their superior polarized sunglass lenses. Wherever you find yourself outside, Maui Jim has a specialized sunglass lens for you.
