We want to dispel the myths and tell you everything you need to know about prescription sunglasses and glasses. If this article helps you out and you want to do a touch of shopping, check out our prescription glasses and prescription sunglasses collection. Everything below has been written to help you make a fully informed decision before you buy your next pair of prescription sunglasses or glasses. 

Choosing the Right Lenses for Your Prescription Sunglasses or Glasses

There are also day-to-day problems caused by some visual impairments that can be solved by choosing the right lenses. Always make sure your prescription is entirely up to date before you buy a pair of prescription sunglasses online. Your prescription can change over time and you might require a slight adjustment before your next pair of prescription lenses.

You may also benefit from enhanced reading glasses, which are designed to work at two different reading distances, allowing you to look through one part of the lenses when you’re reading a book, for example, and another part of the lens when you have to look at something a little further away, such as a tablet or computer screen. There is also the option of getting varifocal lenses, which are like enhanced reading glasses, although they combine two much more distinct distances into one lens. One part of the lens could help you read, and another part could help you see things at a medium distance.

If lenses are listed as ‘single vision’ online, it means that they have only one prescription. Almost all prescription sunglasses will have single-vision lenses. Think long and hard about what you use your prescription sunglasses for most. If you drive a lot and you need a prescription to help you with medium and long distances, then make sure your sunglasses match this prescription. If you use your sunglasses mainly for reading when you’re on holiday, then make sure they help you with short distances.

Choosing the Right Lens Material for Your Prescription Sunglasses or Glasses

Depending on the prescription glasses or sunglasses you choose, your lenses might be made from a different material. Understanding the pros and cons of the different materials will help you understand whether or not the glasses or sunglasses are right for you. Out of all the materials, glass has superior refractive properties and, for this reason, it is usually considered the best choice for prescription lenses. However, glass is also known to crack and shatter if its knocked or put under strain. For this reason, glass isn’t always the best material when you need a tougher pair of sunglasses or glasses, perhaps for when you’re playing sport, for example.

If you’re choosing a material other than glass, then it will either be plastic, Trivex, or polycarbonate. All three of these materials can be engineered in a way that gives them a high index (meaning they can be made thinner and will function as prescription lenses). These three materials are all tougher and more resistant to cracks and scratches than glass is. Out of these three alternatives, Trivex is the strongest, so if you’re choosing prescription glasses or sunglasses with thin lenses or a semi-rimless or rimless style, then you’re best to go for a model that offers Trivex lenses. 

Choosing Between the Different Lens Coatings on Prescription Sunglasses and Glasses

It’s common for lenses on designer sunglasses and glasses to come with a scratch-resistant coating, but you shouldn’t assume that this is the case. When ordering your prescription glasses online, read the product description to find out everything you need to know about the lens coating. If you’re ordering from a reputable company, they should have a product description, or at least a bullet-point list of the glasses’ or sunglasses’ features. However, if the products are brand new, it may just take them a few weeks to write up all of the product descriptions. If you have any questions, you should email or phone the company. You can contact Red Hot Sunglasses on our enquiry page or call us on 0191 466 1118.

All authentic, designer sunglasses will come with a complete UV protective coating, but it’s always worth checking in the description. If anything about the wording confuses you when it comes to the sunglasses UV protection, then get in touch with the vender. Many prescription glasses also come with a coating that protects the wearer from UV rays. They do this without darkening the lenses. Some materials, such as Trivex and polycarbonate automatically filter out UV rays and do not require the additional protective coating.

Oleophobic coating resists oil and thus makes your lenses anti-smudge and resistant to dirt. An oleophobic coating is especially useful if your lenses have an anti-reflective coating, as an anti-reflective coating can make smudges and blemishes especially noticeable. So combining the two coatings together is ideal. So, opting for a combination of coatings is often the best way to ensure your lenses work for you. 

Choosing the Right Frames for Your Prescription Sunglasses and Glasses

The best thing about buying prescription glasses and sunglasses online is the amount of choice you get and the fact that you can buy sunglasses from the top designers at heavily discounted prices. So, choosing frames should be an enjoyable experience for online shoppers. However, you need make sure the frames match your style and that they serve your purposes. Not all frames were created equal, and knowing the differences and what you should be looking for might make all the difference when it’s time for you to buy your next pair of prescription glasses or sunglasses online.

When it comes to shape, it’s important to find a pair of sunglasses that matches your face shape. We’re working on a comprehensive guide that helps people figure out what style of frames suits their face best, and we’ll put the link in here once it is ready. In the meantime, it’s a good rule of thumb to remember to balance out your face with an opposing shape: if you have an angular, square, or rectangular face, then round and curved rims (such as Aviators) are idea for you. And if you have a round or oval face, then angled square and rectangular rims will suit you best.

When it comes to the frame’s material, look out for large frames, as they will require much thinner, more expensive lenses. So this usually factors into the glasses’ or sunglasses’ final cost. It’s also worth watching out for rimless and semi-rimless frames (such as Clubmasters) if your prescription is over +5.00, as these lenses will be so thin that they may be in danger of developing cracks or other damage. It’s also a good idea to ask your optometrist if they think there are any frame shapes you should avoid due to your prescription. 

And that’s all of the advice we have for you in this article. We hope you’ve learned a few things and that you feel better prepared for buying prescription glasses and sunglasses online.
