Spectacles

How quickly can you make up my spectacles?

As we assemble our spectacles in our own workshop, they may take as little as 1 hour to make up. Certain specialised jobs require extra care and may take a little longer. Lenses and frames that need to be ordered from the manufacturers may delay the process, but our Dispenser will advise you of the likely timescale before we proceed.

How thick will my spectacle lenses be?

This depends on your prescription, the type of lenses you choose and the frame style. Generally, the higher the prescription the thicker the lens will be. Use of high index materials, reduction in lens diameter and choosing a frame with a full rim around the lens are all methods of keeping the lens thickness to a minimum. Ultra thin 1.74 index plastic lenses are now available to bring the thickness of plastic lenses more in line with the thinner glass lenses. Our HBD dispensers will be happy to advise you on the best frame and lens choices to suit your prescription.

What are the advantages of plastic over glass lenses?

Plastic lenses are lighter and have 3x the impact resistance of glass lenses. Glass lenses are generally thinner, are more durable to scratches and have slightly higher light transmission than standard plastic lenses.

What are photochromic lenses?

These are lenses, both in glass and plastic, which change from a relatively clear state to dark sunglass tint when exposed to sunlight and UV radiation. Typical brand types of these lenses are Reactolite and Transitions.

What are polarised lenses?

These are specialised tinted lenses that eliminate reflected light from surfaces in addition to direct glare from bright objects. This is very useful for fishermen who have to see through the surface of the water, while having to ignore annoying reflections. They are also of benefit to skiers and sailors. These lenses can be made up with or without your prescription.
