Independent Lens Specialists
As an independent practice, Costspex is not tied to any single lens supplier, and that independence works directly in your favour. Rather than being limited to one manufacturer’s catalogue, we are free to source from across the market, which means we can always find the best value lenses for your particular needs. We work with some of the biggest lens suppliers in the world, alongside a carefully chosen range of independent and local labs, giving us genuine flexibility on quality, price and turnaround.
It also means we can be honest with you about your options, because we have no reason to push one product over another. Our team trials our main lens catalogue and upgrades themselves, so when they recommend something, it comes from real first-hand experience rather than a sales script. That combination of choice, value and honest guidance is at the heart of how we work.

Understanding Your Lens Options
Prescription lenses come in several types, and the right one for you depends on how your eyes work and how you spend your day. Single vision lenses correct for one distance, making them ideal if you need help with either near or distance vision alone. Bifocal lenses combine two prescriptions in a single lens, usually distance at the top and near vision at the bottom, with a visible dividing line between them.
Varifocal lenses, sometimes called progressive lenses, blend multiple prescriptions seamlessly from top to bottom with no visible line, giving clear vision at distance, intermediate and near as your eyes move down the lens. There are also dedicated options such as reading lenses and lenses designed for intermediate tasks like computer work. If you are unsure which type suits you best, our team will talk you through the choices in plain language and help you decide, with no pressure and no hard sell.

Lens Coatings and Upgrades
Beyond the basic prescription, a few well-chosen upgrades can make a real difference to how your lenses look, feel and perform. Anti-reflection coatings cut glare from screens, headlights and overhead lighting, which makes them especially useful for driving and computer work, and they also help your lenses look clearer in photographs. Scratch-resistant coatings add a layer of durability to keep your lenses looking newer for longer, while ultraviolet protection helps shield your eyes from harmful UV rays.
If you have a stronger prescription, thinner and lighter lens materials can make your glasses far more comfortable and less obtrusive to wear. Photochromic lenses, which darken automatically in sunlight and clear again indoors, offer the convenience of glasses and sunglasses in a single pair. Because our team trials these upgrades ourselves, we can give you genuine first-hand advice on which are worth it for your needs, rather than simply selling you extras you may not require.

Frequently Asked Questions
Below are answers to some of the questions we are asked most often about prescription lenses. If there is anything else you would like to know, our team is always happy to help.
We can supply lenses to suit almost any prescription, including single vision for one distance, bifocals that combine two prescriptions in a single lens, and varifocals that blend distance, intermediate and near vision with no visible dividing line. There are also options designed for specific tasks, such as reading or computer work. Because we are independent and not tied to a single supplier, we are free to source from a wide range of manufacturers and labs, so we can match the right type of lens to the way you actually use your eyes.
The best lenses for you depend on your prescription, your lifestyle and how you spend your day, from driving and screen work to reading and hobbies. Our team will take the time to understand your needs and explain the options in plain language, so you can make an informed choice without any pressure. As our staff trial our main lens catalogue and upgrades themselves, the advice you receive comes from genuine first-hand experience rather than a sales script.
For many people, yes. Anti-reflection coatings reduce glare from screens and headlights, scratch-resistant coatings help your lenses last longer, and ultraviolet protection helps shield your eyes from harmful UV. If you have a stronger prescription, thinner and lighter materials can make your glasses far more comfortable to wear. We will only ever recommend the upgrades that genuinely suit your needs and budget, because there is no hard sell here, just honest guidance.
Yes, we will need a current, in-date prescription to make sure your lenses are glazed correctly. If your prescription has expired or you are not sure whether it is still valid, we can carry out a comprehensive eye test at our Durham practice and provide an up-to-date prescription for you. This makes sure your new lenses are as accurate and comfortable as possible.
In many cases, yes. If you have frames you are happy with, our reglaze service lets you keep them while we fit new lenses, whether you are updating your prescription or replacing scratched or worn lenses. We always check the condition of the frame first to make sure a reglaze is possible, as the work is carried out at your own risk.
Once you have chosen the right lenses for your prescription, there are plenty of ways to make the most of them at Costspex. If you are looking for new frames to pair with your lenses, you can browse our full range of prescription glasses or explore our designer frames for something with a recognised name. If you would like your lenses tinted, we can turn any complete pair into prescription sunglasses for just £10 extra, making it an affordable way to get a dedicated pair for sunny days. If your prescription has expired and you need it updating before we can glaze your lenses, our eye test service covers everything you need, with NHS eye tests available for those who are eligible. And if you already have frames you love, our reglaze service lets you keep them while we fit your new lenses, starting from just £35. Our team will always help you find the right combination of frames and lenses to suit your needs and your budget.
