• Cr39 plastic lenses can scratch quite easily if not treated carefully, so a much harder plastic coating is added to the surface to help reduce scratching.
• We do not charge for scratch resistant coating on any lens we supply.

• Applies if your sph and cyl added together is greater -/+ 6.00 or your cyl is greater than -/+ 2.00 or a prism is prescribed

Bifocals £30.00 extra.

Varifocals --- Budget Varifocal £85.00 Extra --- Premium Varifocal £130.00 Extra

A varifocal lens corrects vision at various focal lengths - near, far and intermediate.

Varilux invented varifocals and sometimes these two names can be confused.

However, it is important to remember that not every varifocal is actually a Varilux lens. As well as inventing varifocal technology in the 50s, Varilux has been responsible for many great strides in its development. Today, the period of adjustment to Varilux varifocals is shorter than with other varifocals.

Varilux lenses give you sharp, effortless vision from short to mid to long distance and back again.

All Varilux lenses now bear a tiny laser etched signature to ensure you have the genuine product.

You also receive a 'Certificate of Origin' in the form of a Guarantee Card, and all Varilux lenses are covered by an adaptation guarantee which means your optical supplier will replace the lens with another type of lens in the very unlikely event that you are unhappy with your Varilux lenses.

Our budget varifocal is a Varilux Liberty, made by a leading UK manufacturer who advertise their products regularly on TV

Premium Varifocal £130.00 Extra

The premium varifocal we supply is a Varilux Comfort made by a leading UK manufacturer who advertise their products regularly on TV

All Varilux lenses are covered by an adaptation guarantee which means we will replace the lens with another type of lens in the very unlikely event that you are unhappy with your Varilux lenses.

When ordering varifocals we need to know the Pd measurement and the height of your pupil within your selected frame, this can be obtained by uploading your calibrated image and trying on your selected frame in our click and measure virtual mirror.

• Transition lenses ® have a very thin layer of photochromic material bonded onto the front surface of the lens, thus giving an even density when activated.
• There do exist some other less attractive photochromic lenses that change colour throughout the entire thickness of the lens, they are cheaper to make but give a darker tint in thicker areas of the activated lens and have a patchy appearance.
• We only supply genuine Transitions lenses ® not cheaper poor performance lenses as supplied by some other less scrupulous companies.
• Grey Transitions Lenses ® I would describe as a cooler colour.
