Multifocal lenses have made everyday life much easier for people over forty. Bifocals were invented sometime in the 1700s, but trifocals and eventually progressive lenses were later created to give wearers even more functionality. The options are great, but making the choice can be difficult!

If you need multifocal lenses to provide you more than one power, progressive lenses may be a perfect fit. They have many benefits and can work in almost any setting.

Here are some things to consider for your progressive lenses.

How Progressive Lenses Work
Progressive lenses are called “progressive” because they gradually change from one magnification to a stronger one at the bottom of the lens. They progress from a distance vision prescription to an intermediate and then a near-field one. This means that the wearer can look up to the horizon in the upper portion of the lens and see distances clearly, use the middle of the lens to look around their intermediate space, and view reading materials and close up objects through the bottom of the lens. This use of progressive lenses becomes second nature after some adjustment.

Are Progressive Lenses Better than Bifocals?
Many people prefer progressive lenses over bifocals for two reasons. First, bifocals only have two prescription powers. They usually address a farther distance and a close-up reading view. Either an intermediate distance or a certain distance will not be completely clear. Second, some people are distracted by the “image jump” that they see when looking through bifocals. This is caused by the abrupt line where the inset meets the rest of the lens. Some people love bifocals and see no added benefits from progressive lenses, but most people like the versatility of progressive lenses.

Additional Benefits of Modern Progressive Lenses
Multifocal lenses that are not progressive sometimes don’t fit well within a certain frame size. Because lenses have to be cut to fit the frame, the reading portion can end up too big or too small compared to the lens size. Short corridor progressive lenses address this by scaling the reading zones into a more compact area. This means wearers still have their pick of frames and eyeglass shapes.

In addition, specialty progressive eyewear exists to meet certain needs. Computer eyewear can be a great option for people who work at a desktop setting. These lenses do not need the addition of a distance vision section. This means that they allow more room for a close distance focus, and then the rest of the lens is created for the intermediate field. With a computer screen sitting at arm’s length, reading materials up close, and walls at an intermediate distance, these lenses help maximize the eyewear for indoor occupational settings.

Nobody will notice! Some people believe there is a stigma with bifocals because they perceive them as glasses only for senior citizens. Many people even put off getting multifocal lenses because they don’t want to admit that they need them. Progressive lenses help this issue for some people because there is not a visible line like with bifocals. It is unusual for someone to notice that the wearer has progressive lenses unlike the ability to see bifocal lines.

If you have any questions about how progressive lenses can help your eyes see as clearly and comfortably as possible, speak with an optician. There are many options and we can help you narrow down the possibilities so you can make an informed decision.

Eyeglass lens options have grown incredibly in the last several decades. Whereas early eyeglass lenses were made from glass, advancements in lens materials have made them safer, thinner, lighter, and featuring benefits that early inventors never could have imagined!

Glass lenses revolutionized so many aspects of life for people of that time. Glass can provide crisp, clear views, but it is heavy and breakable. It was not uncommon for lenses to break on impact, which could cause someone to lose sight or lose the eye entirely. For that reason, glass is rarely used for eyeglasses today.

In the 1940s, plastic lenses were introduced. Armorlite Lens Company created a lightweight plastic lens made of plastic polymer. It was light, weighing about half as much as a glass lens, and was inexpensive. These plastic lenses were a hit, and are still a common option for eyeglasses today.

Polycarbonate lenses were introduced in the 1970s. Polycarbonate is a highly durable polymer that is impact-resistant, but can scratch. For this reason, the lenses are recommended for children and used in most eyeglasses, but have the addition of a hard coating to deliver greater scratch resistance.

High-index lenses are another lens option that many people aren’t aware of when they begin shopping for eyeglasses. High-index plastic materials make lenses thinner and lighter for people who have a strong prescription. Instead of thick lenses that used to give people fewer options for lenses and make their eyes look distorted from the front, high-index lenses can pack a stronger prescription into a thinner space. This opens more frame options and takes the weight off of your glasses if you have a high prescription!

In addition to lens materials, there are a number of other features that you can add to your lenses for various functionality. For instance, anti-reflective or non-glare treatments are one of the most common upgrades. Often they give added scratch-resistance as well as cutting glares and giving a clearer view of your eyes from the front. Tints are another option you can add to your lenses. For sunglasses, wearers might choose around an 85% tint, but lighter options exist, too. Many lenses can be tinted gray, brown, or yellow. Fashion tints come in rose, blue, green, or even more possibilities. Polarization is a great addition for sunglass lenses, too, because it filters the bright glares that can be uncomfortable, even with sunglass tints.

If you have any questions about the best lenses for your eyes, speak with an optician. They are trained in eyecare products and can assist you with these choices, as well as helping you pick frames that look great on you!
