There is a difference between 1.67 and 1.74 high index lens.
Shopping for eyeglasses can be difficult.Unless you are an expert, you don't know what to choose in order to maximize your opportunities and get exactly what you need.Too often, you choose an option that isn't ideal for your needs and wants.
That is true when it comes to high index glasses.The concept can be hard to understand for people not used to it.There are a number of distinctions you need to know in order to find a pair that matches your needs.
How do you pick?Where do you start?The difference between 1.67 and 1.74 is one of the most basic differences within this category.This article will take a closer look at that difference before going into the reasons you might want to pick one option over the other.
The materials for lens never stop evolving.We have come a long way from the thick glass that defined vision enhancement options.New technologies allow for more distinction, clearing your vision even on strong prescriptions without acting as an impediment or fashion faux pas.
The high index lens is an example.The function of a lens is to bend the light as it passes through the glass.It corrects the vision that requires prescriptions.The light needs to be bent if the prescription is strong.
Mostlens are not equally thick across the spectrum.If you are nearsighted, they are thinner in the center and thicker on the edges.If you are farsighted, your lens will be thinner on the edges and thicker in the center.
There are a number of problems.Your glasses need to keep getting thicker as your prescription strength increases.That is not the case with regular glasses.High index alternatives are designed to keep the thickness to a minimum.The light can be evenly thick on both the edges and the center regardless of whether you are near or farsighted.
Many people who wear glasses choose high index lens as their prescriptions get stronger.It helps you keep your glasses light and thin.People with strong prescriptions who don't want to show off their failing eyesight are more likely to buy glasses with this lens type.
Your options are not done yet.Not every option in this area is created equal.Far from it.As you pick the perfect pair of prescription glasses, you can choose from various indexes.
The index ranges from 1.5 to 1.74 for any type of eye-wear.A standard plastic is about 1.5.The difference to regular eye-wear is minute, though high-index options start at 1.53.The thinner the lens, the stronger it is with the strongest prescriptions.
The latter is simply thinner and lighter than the former.The thinner the lens, the higher the refraction index.
There is a basic definition of the difference between the two options, so it is time to look into the reasons you should choose one or the other.1.67 high index lens is a common choice in many scenarios.
If your prescription is still at medium level, choose a 1.67 level.The prescription should be between -6.00 and -8.00 diopters.As you evaluate your next pair of glasses, you will begin to think about thickness.There are high index options that are relevant.
You don't need the highest index yet.It would cost a lot of money to choose it, and the return isn't necessarily there.For your needs at this level, 1.67 refraction index glasses offer a great mix of price, durability, and convenience.
A middle-aged female who wants to dress professionally in an executive-level job might find this option appealing.She might no longer be served well by regular plastic glasses because they are becoming heavy and uncomfortable.The high index glasses at the 1.67 offer the right amount of durability, thinness and light weight without breaking the bank.
It is possible that 1.67 index glasses no longer work for you.They will use their utility at some point, but are significantly more expensive than plastic or regular glass options.It is time to look at other alternatives that can do a better job while maintaining both fashion and function utility.
When your diopter level goes beyond -8.00, most eye care professionals recommend looking at this option.High index glasses may no longer be able to do the trick.It is possible that you will suffer from a lack of comfort, distortion around the edges of your lens, or glasses that just do not look the part anymore.
The more relevant 1.74 refraction index enters the equation here.It is the highest you can go.You minimize the problems you might experience with weight or thickness in the process.You get a pair of glasses for strong prescriptions.
Imagine a professional getting a promotion to CEO.Her eyesight is getting worse.She needs to look professional at the first board meeting.The 1.74 high index lens is the perfect choice for her.The added cost comes with utility, style, and function advantages.
Whether 1.67 or 1.74 works better for you is only the beginning.What type of lens additions and improvements you need to maximize their utility should be your next consideration.
Anti-reflective coating is an example.High index lens block more light than regular plastic or glass alternatives.They might need more help to reduce the reflection on your glasses.Even in a glaring sun, the anti-reflective coating ensures you can see clearly.
High index materials can be added to most lens options.If you have a higher index, you can get your progressive lens.You can still benefit from the light weight and lack of thickness that high index lens can provide, as you minimize the negative effects of bifocals and turn your regular glasses into sunglasses.
There are many benefits to choosing this type of lens.You have to go through the process the right way to realize them.You can't just buy the first pair of glasses online and hope for the best.The process needs to be more strategic.
You need to get an updated prescription from your eye doctor.If you don't have it, you might not know if you need high index glasses.It makes sense to ask the professional what they recommend for you.It can help you make the tough decision of choosing 1.67 over 1.74 or vice versa.
The context should be considered next.Some add-on choices are already discussed, but they are not the only ones.It's important to understand how you can enhance your lens for maximum utility before you buy them.
The frame is part of the context.It never hurts to double-check that high index lens fit in most frames.Before you buy a specific frame, make sure it fits the lens you need for optimum vision and comfort.
