Blue light glasses are popular for good reason. We spend a huge portion of our days looking at screens people check their smartphones every 6.5 minutes on average, and 55.5 percent of employed Americans work with a computer every day.We rely on our digital devices,and our connectivity is not going anywhere anytime soon. In the past four years alone, the number of smartphone owners has increased by 82 percent,and this number is still on the rise. However, this increased connectivity comes with risks especially to our eyesight.

The biggest source of potential harm from digital screens is blue light. This part of the visual spectrum is a short- wavelength light, which can be found in just about everything from sunshine to computer screens. Unlike blue- turquoise light, which is healthy and beneficial for us, blue-violet light, such as the high-energy visible light from backlit screens and artificial lighting, can be damaging to our eyes after excessive exposure.

Up to 75 percent of computer users experience discomfort after using their screens for a long period of time, and considering what looking at screens does to our eyes, its not surprising. Extended use of digital devices makes our eyes work harder, requiring them to constantly maintain focus.

Youve found the perfect frames, but you now have to choose your lenses. You might be wondering what the different types of lenses for glasses are. Finding the right lenses for you is just as important as getting frames that fit your face and lifestyle.

So, what are the different types of lenses for glasses?

What Are Multifocal Eyeglass Lenses

If you’re in your mid-40s or older, you probably have glasses with multifocal lenses, like bifocals or trifocals. These have two or more prescriptions to correct your vision. In the past, you could spot this type of lens by the line between the two sections. But todayâs products often look seamless.

Bifocals. The most common type of multifocal. The lens is split into two sections. The upper part helps with distance vision. The lower half is for near vision. Theyâre usually prescribed for people over 40 who canât focus well anymore. Thatâs due to presbyopia, an age-related change that affects your eye’s lens.

Trifocals. These are bifocals with a third section. It sits above the bifocal portion of the lens. You look through it to see objects within arm’s reach, like a computer screen.

There are also progressive lenses, which have no line, and start with your distance prescription at the top and progressively move toward your full reading prescription at the very bottom.

If you have questions about which type is right for you, talk to your eye doctor. They can help you choose the one that best fits your lifestyle and vision needs.

Figuring Out What Looks Good On You

Choosing sunglasses isnt all about sun protection and visual performance, of course. You also want your shades to flatter you. A good place to start is determining the shape of your face from there, you can get a sense of which styles do and dont work for you.

  • A square-shaped face is about as wide as it is long, with a pronounced jawline. If this describes you, your best bet are sunglasses with rounded frames, or frames with a slight curve aviators, for example to soften the angles.

  • If your face is round, its also about as wide as it is long, only with a more rounded jawline. To give yourself some angles, consider square or rectangular frame shapes, but avoid oversized frames that can add too much width. Aviator frames, with their slight curve, may also be a great choice for you.

  • A heart-shaped face is like a triangle, with a broader forehead and narrower chin. If this is your face shape, you can minimize the width of the top part of your face with rounder frames, or classic Ray-Ban Wayfarer sunglasses.

  • An oval face is slightly longer than it is wide. The good news if this describes you: Just about any style of frame can work, so try aviators, Wayfarers, wraparounds or any geometric shape that suits your personality.

  • If your face is long and narrow, its oblong-shaped. Consider oversized frames, rectangular Wayfarers, aviators and bold shapes just avoid very narrow or small lenses that may emphasize the narrowness of your face.

  • Polycarbonate lenses, on the other hand, were introduced in the 1970s. It is lighter than regular plastic lenses and is an excellent material for sports eyewear, kids glasses, and safety glasses.
  • Trivex lenses, introduced in 2001, are a good substitute for polycarbonate lenses because of their impact resistance characteristics and much lighter weight of about 10%. Trivex lenses also produce sharper vision compared to polycarbonate lenses.
  • High-index plastic lenses refract light more proficiently than glass or plastic lenses. This material has a higher index of refraction which produces thinner glasses. This material is beneficial for a higher prescription for nearsightedness, farsightedness, or astigmatism.

If you choose designer frames and aspheric, high-index progressive lenses with AR coating, the cost can be high. It’s not unusual for the cost of eyeglasses of this type to exceed $800 or more.

    Bifocal

    See a line in the lens? Then it is a bifocal. Originally invented by Benjamin Franklin, bifocals include two different areas of vision correction divided by a distinct line that sits horizontally across the lens. The top portion of the lens is used for distance and the bottom portion is for close vision.

    Progressive

    Known as no-line bifocals, progressive lenses are a perfect marriage of form and function. With no lines across the lens, others wont even know youre wearing a multi-focal lens. They provide a graduated range of vision that varies from seeing distance on the top to reading on the bottom. This is often the best lens for vision correction at all distances.

    Trifocals

    With trifocal lenses, you get three focal points in one lens. The lens powers start with close vision at the bottom of the lens, mid-vision through the middle and distance through the top. While still preferred by some, trifocals are becoming less common with more people opting for seamless, progressive lenses.
