Lenstore is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lenstore rather than just read about it. In short: Lenstore is a British online optical retailer, specialising in contact lenses and eye care products. History Lenstore was founded on 3 January 2008 by Oxford graduate, Mitesh Patel.

Key takeaways

Lenstore belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lenstore to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lenstore from memory before moving on to harder problems.

Reference excerpt

Lenstore is a British online optical retailer, specialising in contact lenses and eye care products.

History Lenstore was founded on 3 January 2008 by Oxford graduate, Mitesh Patel. The website went live on 11 June 2008 and by 2012 the company had entered the Sunday Times Fast Track 100 in 10th place. Lenstore had served over 100,000 customers by 2013, despite not being the only online-only lens and glasses retailer in the UK. This growth was aided by a desire in the UK to buy lenses cheaper, and not just from high street opticians. Guides were subsequently created to help UK customers identify the correct lens to purchase online (as high street opticians would often rebrand lenses). In late 2013, the start-up was acquired by GrandVision. This saw Lenstore become a sister company to UK high-street optician Vision Express, allowing the company to offer customers face-to-face eye care. A version of the Lenstore website was launched in Germany in 2016.

In the media In April 2018 Lenstore & Nikon created the world's first gigapixel timelapse, with London as the subject. The 7.3 gigapixel timelapse was taken from the top of Canary Wharf using a Nikon D850 camera and a Nikon AF-S NIKKOR 300mm lens. In 2019 Lenstore teamed up with charity Colour Blindness Awareness UK to highlight the plight of people with colour blindness by showcasing how they see the world. The campaign highlighted 3 different types of colour blindness including Tritanopia, Protanopia and Deuteranopia.

Worked examples

Example 1 — a first encounter with Lenstore

Start with the simplest possible case. Write down what Lenstore claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lenstore before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lenstore ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lenstore

In research: Lenstore appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lenstore in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lenstore is common in secondary-school and first-year university syllabi. It links to neighbouring topics British companies established in 2008, British opticians, Companies based in the London Borough of Merton, so understanding it makes those chapters shorter.
In everyday life: Look for Lenstore outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
