Thin and light plastic and glass lenses

Here you can order high prescription lenses online with powers ranging from -30.00 to +25.00

Thin plastic lenses

You have likely found us because you have a high strength or complex prescription.

We provide a reglazing service to put new thin, aspheric, double-aspheric plastic or glass lenses into your own frame. We can cater for high strength prescriptions ranging from -30.00 to +25.00!

We offer a comprehensive range of premium high index spherical, aspheric and double aspheric (also known as bi-aspheric) from Zeiss, Seiko and Tokai. We also offer Zeiss SV ClearView which are even more precise than a double aspheric because they are manufactured using point-by-point optimisation across the entire lens.

Thin glass lenses

For glass lenses we only offer premium Zeiss single vision (SV) glass range in 1.6, 1.7, 1.8 and 1.9. All Zeiss glass lenses come complete with the Zeiss Super ET anti-reflective coating.

Glass is thinner than plastic, so a 1.6 glass lens will be thinner than a 1.6 plastic lens of the same power despite them being the same index. Glass is also more durable than plastic, but it is heavier.

Buying high prescription glass lenses online is exactly the same as buying high prescription plastic lenses online.

Buying stronger prescription lenses online

Please check that our standard lens reglazing prices are not cheaper. We provide 1.5, 1.53, 1.6 and 1.67 in our standard lens prices. We just offer the same indexes, with the inclusion of 1.7, 1.76 and 1.6, 1.7, 1.8 and 1.9 Glass in a larger range on our specialist aspheric, double aspheric (Bi-aspheric) and glass reglazing services..

Aspheric, double aspheric and bi-aspheric?

Double aspheric and bi-aspheric are the same thing. This means, when the lens is made, both front and back surfaces of the lens are surfaced with an irregular curve, making the lenses even flatter and thinner than a standard aspheric lens. Aspheric lenses are only surfaced on the front surface of the lens.

The high prescription lenses we provide

In-house aspheric

These lenses are conventionally surfaced and come complete with a scratch resistant and anti-reflective coating. They are also UV safe.

Spherical / Aspheric / ClearView

Zeiss spherical lenses are good for lower prescriptions but aspheric are better when it comes to performance for higher prescription powers. Spherical will still be a great lens if you are looking for thinner lenses on a budget.

Aspheric ‘Zeiss AS‘ lenses have a flatter front curvature and are thinner than a spherical lens of the same power.

Zeiss single vision ClearView lenses are made using more precise freeform technology (read more). This gives better clarity and visual performance across the entire lens.

All Zeiss lenses come complete with Zeiss Duravision Platinum UV coating.

Lutina /Bi-aspheric

Ocular diseases are believed to be caused by oxidative stress. Lutein is one of three carotenoid pigments and without a sufficient amount of lutein protecting the macula this can lead to an increased risk of AMD (Age-Related Macular Degeneration). AMD is the most common cause of vision loss in those aged 50+.

Tokai Lutina lenses have the ability to absorb light in the ranges of 400nm – 420nm. This is the range for high energy violet light. By cutting out 94% of this light the Lutina lenses can help to preserve optical health.

All Tokai lenses come with either the NRC (No Reflection Coating) or the PGC clean multi coating which is super-oleophobic and easy to clean.

Double aspheric

Manufactured using Seiko Digital Surfacing.

Sharper and improved clarity across the entire lens. Minimising astigmatic aberrations (great for those with higher cylinder (CYL) powers. Enjoy relaxed vision across a thinner lens, while also benefitting from the reduction in magnification of the eye for those with PLUS (far-sighted/long-sighted) prescriptions.

All Seiko lenses come with the choice of the Seiko SRC (SuperResistantCoat) or SRB (SuperReducedBlue) coatings.

The manufacturing process

Measurement

We use a focimeter to measure the optical centres of your existing lenses.

We mark the lenses at these points and that tells us your exact pupil distance measurement and if the lenses have a fitting height measurement (where the optical centre of the lens is set directly in front of your pupil, rather than on the horizontal centre line of the frame).

lens cutting reglazing glasses online

Set and cut

When the lenses are still in the uncut stage i.e. not cut to the shape of your frame yet, we set the axis of your lenses on a blocker, and we then put the lenses into a lens edger.

We then guide the bevel of the lens to be in the best position for the lens thickness and the curvature of the frame. This is a very important step with high minus lenses.

Fitting

We then fit the lenses to your frame.

With plastic frames, they are heated to allow the lens to slot into the rim easily.

With high minus lenses, this is the stage where an edge chamfer may need to be added, by hand, to give the best aesthetic appearance.

Verify

This is very similar to the first step when we measured your pupil distance.

We put the frame, complete with the newly fitted lenses, back onto the focimeter and check the powers are correct, the pupil distance and fitting heights are correct, that there are no marks on the lenses and that the frame is set up squarely.

The frame then passes inspection and is ready for dispatch.

What is an aspheric lens?

Spherical prescription lenses

Spherical

Spherical lenses are the standard lenses used in prescription glasses on standard 1.5 index and 1.6 index. It is when the lenses are 1.67 or above that they are usually aspheric in design by default.

Spherical lens sphere power recommendation: Up to and including -/+3.00.

Aspheric prescription lenses

Aspheric

Double aspheric or bi aspheric (same thing!) lenses will greatly benefit wearers will higher sphere powers and especially those with astigmatism (if you have cylinder values on your prescription). The lenses help to reduce the magnification of the eye for plus powers (far sighted) and reduce minification for minus powers (near/short sighted). When combined with a higher index lens, double / bi aspheric lenses are the best lenses available for improving the cosmetic appearance of your lenses.

Double / bi aspheric lens sphere power recommendation: greater than +/-6.00

Double / Bi Aspheric

Double aspheric or bi aspheric (same thing!) lenses will greatly benefit wearers will higher sphere powers and especially those with astigmatism (if you have cylinder values on your prescription). The lenses help to reduce the magnification of the eye for plus powers (far sighted) and reduce minification for minus powers (near/short sighted). When combined with a higher index lens, double / bi aspheric lenses are the best lenses available for improving the cosmetic appearance of your lenses.

Double / bi aspheric lens sphere power recommendation: greater than +/-6.00

Clearview / Freeform

Where double-aspheric lenses are optimised in two perpendicular meridians, Freeform Single Vision lenses are manufactured using point-by-point optimisation resulting in a very complex lens surface, but one that is very thin and flat while also achieving excellent optics.

FAQ for high prescription lenses

Most frequent questions and answers

Absolutely. This is actually what we recommend to do because this way we can measure the pupil distance and fitting height measurements from your existing lenses.

Yes. The glass lenses we supply are by Zeiss. We provide 1.6, 1.7, 1.8 and 1.9 index glass.

This is possible with high prescription lenses, however we will still need you to send an older frame to us so we can measure your pupil distance from the old lenses – this does not have to be an existing prescription.

If you do not own a pair of glasses, and you require high prescription lenses, we would recommend that your first pair of frame and lenses be purchased from your local independent optician. This is because we need a very accurate PD measurement. If you do not have any glasses to send to us, we do not have anything to measure from.

The sphere power on your prescription is the main thing to look at.

Our recommendations:

Spherical – Up to and including +/-3.00
Aspheric – From +/-3.00 to +/-6.00
Double aspheric/Freeform – +/-6.00or higher
