Progressive Lenses: Pros & Cons, and What to Expecthttps://vieweyes.com/wp-content/themes/corpus/images/empty/thumbnail.jpg150150jometry1jometry1https://secure.gravatar.com/avatar/7486e1f60e2e06f25469185dfc318e41?s=96&d=mm&r=g
When shopping for prescription eyewear you will be presented with a selection of various lenses. These are Single Vision, Bi-Focal, Tri-Focal, and Progressive. Single Vision Lenses come in one strength. Bi-Focal and Tri-Focal come in two and three strengths respectively. Bi-Focal and Tri-Focal have a very clear cut between strengths known as “line”. While this cut might work, it has become out of fashion. Here is were Progressive Additional Lenses (PAL), also known as Progressive or No-Line lenses come into the equation. These lenses come in variable strength without the line making them more sleek and fashionable than its older variants.
No line Bifocal Progressive Lenses
What are progressives?
Progressive lenses are specifically made for patients that require corrective lenses for both distant and nearby objects. To put it simply, if you want one pair of glasses and don’t want a line, progressives are your best option.
Pros
Progressives solve many of the issues and inconveniences of having multiple glasses, or Bi-Focal lenses. No need to switch between glasses, there is no distracting line, and they look much more modern and sleek.
1. One pair of Glasses
Let’s be honest, nobody wants to carry an extra pair of glasses and having to switch between distance and reading. Think of it this way, your smartphone is a phone, a calculator, a map, among other things. Progressives are the smartphone of lenses, combining reading, and distance in a nice sleek package.
2. No line
Nobody likes lines. Lines are boring, lines are ugly. You don’t see people standing in line at the grocery store praising the fact that they have to stand for minutes waiting to pay for their groceries. While progressive lenses might not get rid of the line at the DMV or the grocery store, they do get rid of the line in your lenses. One less line to worry about.
3. Modern look
You probably wear your glasses everywhere so looking fashionable all the time is very important. You don’t have to settle just because you need multiple powers. While we at View Optical Eyeglasses Store aren’t fashion experts, we do know that progressives are way cooler than Bi-Focal.
Cons
Nothing is perfect, and that includes Progressive Lenses. You may notice distortion at the edges of your lens, it might take a few days to get comfortable wearing your glasses, and they tend to cost more.
1. Distortions on the edges
Hold your horses, we love progressive lenses but there are some things to need to keep in mind. To be able to go from one strength to another without a line some sacrifices have to be made. Distortion on the edges are a real thing. While they might be distracting at first, once you get used to your new pair of Progressive Lenses, you will not notice them.
2. Need to train your eyes
Something we see at our store almost every day is patients who can’t read from their progressive lenses properly. This is a common issue when you get a new pair of Progressives. Unlike glasses with a line, you can’t pin-point the perfect place to read from, it takes a few days for your eyes to find the perfect spot for reading. Think of it muscle memory but for your eyes.
3. Higher cost
Technology comes at a price. Progressive Lenses are more expensive to manufacture so they come at a premium compared to Bi-Focal lenses. Nevertheless, the convenience and simplicity of having one pair of eyeglasses is something our patients feel is worth it.
Are progressive lenses for me?
We at View Optical Eyeglasses Store in Fremont, love our progressive lenses. Our technicians at our state of the art optical laboratory are huge fans. But we understand Progressive Lenses are not the right choice for everyone. Some patients may have problems adjusting to their progressive lenses which sometimes can be solved readjusting the strength of of their lens. For patients that work in front of their computer we recommend our Computer Progressive Lenses, which are stronger for intermediate distance.
Takeaway
Progressive lenses can seem a bit complicated to use at first, but once you master them you will love them. Remember, you will need to pick the right material for your glasses, so read our Eyeglass Lenses Materials Guide to learn more. Next time you visit your Eye Care Specialist ask about progressive lenses to make sure if they are right for you. If you are located in or around Fremont, California you can book an appointment with our Independent Optometrist.

How to Wear Contact Lenseshttps://vieweyes.com/wp-content/uploads/2015/06/colored-contact-lenses-600x400.jpg600400jometry1jometry1https://secure.gravatar.com/avatar/7486e1f60e2e06f25469185dfc318e41?s=96&d=mm&r=g
Nervous? Don’t be. Putting contact lenses in and taking them out is easier than you might think. It may take a few days for your eyes to get used to the feeling of wearing lenses. If you’re having trouble don’t force it, give yourself plenty of time to get comfortable. There’s no rush, you can always try again tomorrow.
Daily Disposable Contact Lenses
Care
Daily disposable contacts are inserted on the eye every morning and thrown away every night, so you don’t need care solutions.
Lifestyle
One and done is an easy care routine for many first-time wearers or people with active lifestyles.
2-Week Contact Lenses
Care
Simply clean daily and store in lens solution overnight to maintain safety and cleanliness.
Lifestyle
2-week contacts require basic care and upkeep, but also enable you to have one pair for a longer period of time than just a day.
Monthly Contact Lenses
Care
Basic care and upkeep—storing and cleaning in lens solution overnight—allows you to keep them for an extended period of time.
Lifestyle
Because you’ll have these longer, they require some amount of responsibility to keep them clean.
How long will it take for the contacts to feel normal?
This varies for everyone. If you feel like it has been too long, the best way to find out why you’re uncomfortable, and what you can do about it, is to talk to your eye doctor.
Should the contact move around after I put it in?
With proper fitting, contacts should stay in place almost all the time. Even on that rare occasion when a contact lens moves out of place, it usually stays on your eye until you can move it back.
Is it okay if my vision is still blurry after putting in my contacts?
Many things can adversely affect your vision. It could be as simple as dry eyes, poor-fitting lenses, or an out-of-date prescription. It could also be a sign of a more serious problem not related to your contacts. You should always talk to your eye doctor about any issues you are having with your vision or your contact lenses.
Polycarbonate vs. Trivex Eyeglasseshttps://vieweyes.com/wp-content/uploads/2015/06/safety-glasses-x.jpg450300jometry1jometry1https://secure.gravatar.com/avatar/7486e1f60e2e06f25469185dfc318e41?s=96&d=mm&r=g
When Eye Safty is a concern, polycarbonate or Trivex lenses usually are the best choice for your eyeglasses, sunglasses and sports eyewear.
Both polycarbonate and Trivex lenses are thinner and lighter than regular plastic lenses. They also offer 100 percent protection from the sun’s harmful UV light and are up to 10 times more impact-resistant than plastic or glass lenses.
This combination of lightweight comfort, UV protection and impact resistance also makes these lenses an excellent choice for children’s glasses and safety glasses.
Polycarbonate Lenses
polycarbonate lenses have become the standard for safety glasses, sports goggles and children’s eyewear. Because they are less likely to fracture than regular plastic lenses, polycarbonate lenses also are a good choice for rimless eyewear designs where the lenses are attached to the frame components with drill mountings.
Light weight (Up to 20% lighter and thinner than plastic CR-39)
Impact-resistant lenses. (up to 10 times more impact-resistant )
UV Protection (100% UV Protection So if you chose Polycarbonate Lenses, don’t pay for UV coating )
Trivex Lenses
Thickness. Polycarbonate has a higher index of refraction than Trivex (1.58 vs. 1.53), so polycarbonate lenses are about 10 percent thinner than Trivex lenses.
Weight. Trivex has a lower specific gravity than polycarbonate, making Trivex lenses about 10 percent lighter than polycarbonate lenses.
Optical clarity (central). Trivex lenses have less internal stress and may produce sharper central vision than polycarbonate lenses.
Optical clarity (peripheral). Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses.
Impact resistance. Polycarbonate and Trivex lenses have comparable impact resistance.
UV protection. Polycarbonate and Trivex lenses both block 100 percent of the sun’s UV rays without the need for special UV-blocking lens coatings.
Availability. Polycarbonate lenses are available in a wider variety of lens designs ( progressive lenses and other multifocals) than Trivex lenses.
