We need to get your bifocal or varifocal lenses right, this is how it works *

When you order bifoclas or varifocals we send the frames out to you before making your prescription lenses. You will use the frames to take some important measurments. Next, you'll send back your frames free of charge so that we can produce your perfect prescription lenses. We know some other websites don't do this, but we think it's important to get your glasses right. Any questions, please do contact us!

Add transitions lenses? *

Transition lenses are the lenses that darken in the sunlight and lighten in softer light or the dark. They offer both style and convenience, and can help protect your eyes from UV. Our lenses use genuine Transitions technology.

XTRActive Transition lenses - work in direct sunlight + work behind glass + when driving (+£80.00)

Regular Transition lenses - work in direct sunlight (+£65.00)

No thanks

What colour transitions lenses would you like? *

Brown

Grey

Would you like to add Blue Shield Technology? *

Blue shield technology includes a blue light blocker to reduce exposure to potentially harmful light from extended periods using electronic devices like phones, tablets and laptops. It also includes an anti-reflective coating to reduce glare and increase the amount of visible light passing through the lens. Plus toughened surfaces reduce the amount and effect of scratches.

Yes - Add Blue Shield Technology (+£25.00)

TGM4: ultra-thin 1.74 index lenses + anti-scratch coatings + anti-reflection coatings + UV 400 protection (+£65.00)

Want to add UV 400 protection? *

UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.

Yes add UV 400 protection (+£15.00)

All new for 2020, the Advanced Quantum PAR Meter provides accurate and cost-effective measurement for all light sources used to grow plants.  The PHOTOBIO by Phantom Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis in plants, which is important for horticultural studies and monitoring plant physiology. 

The Advanced light meter comes complete with a remote sensor, two connection cables, the main unit and easy to replace AAA batteries. The PAR meter can store up to 99 measurements for easy reference. 

• Portable PAR meter with highly accurate remote quantum sensor
• Measures photosynthetically active radiation (PAR) from 400 to 700 nm
• Simple and easy to use
• Record up to 99 readings
• Includes short coiled and long straight connection cables
• Fully portable handheld light meter
• Measures up to 10,000 in units of micro-mol per meter squared per second (umol/m2/s) which is also called Photosynthetic Photon Flux Density (PPFD)
• Tethers to computers via USB cable for easy data logging
• Proprietary Quantum Sensor
• Ultra-low power consumption with built-in low battery indicator
• Proprietary data logging software
• Response curve is almost constant (versus Gaussian for digital meters) which yields a much higher accuracy independent of wavelength being measured- great for measuring LED light correctly
