There are lens implants, which give focus at all distances. There are limitations and you should consult with your surgeon about them.

A bifocal lens only allows you to have two vision distances (near and far) while progressive lenses give you all your range of vision from distance, intermediate and near in a smooth progression. Most people like the newer technology of the progressive because it allows for more natural vision and cosmetically they look nicer because there is no line. The upside to standard lined bifocals is that the peripheral vision is sometimes better.

The ReZOOM and ReSTOR multifocal lens implants have been proven safe and effective by ophthalmologists for thousands of eyes worldwide. It is usually performed with small incision techniques that don’t require stitches. Once in place, the ReZOOM or ReSTOR multifocal lens implant allows you to see objects at all distances. This procedure makes it possible for most people to greatly reduce or eliminate the need for bifocals or reading glasses.

In addition to a correction for nearsightedness, farsightedness, and/or astigmatism, a bifocal contains an addition for near vision. There are two focal powers.

The lens is the part of the eye that helps focus light on the retina. The retina is the eye's light-sensitive layer that sends visual signals to the brain. In a normal eye, light passes through the lens and gets focused on the retina. To help produce a sharp image, the lens must remain clear.

A lens implant (intraocular lens or IOL) is a man-made, clear plastic lens approximately 6 mm in diameter which is placed inside the eye at the time the cataract is removed. It replaces the natural lens and remains permanently within the eye. The lens has small spring-like arms called haptics that prevent the lens from moving out of place.

We only offer the service of reglazing your old frames with varifocal or bifocal lenses if you have theses lenses already fitted in your frames. We can provide this service only because we can glaze the new lenses into your old frames by using your old lens setting.

Yes we do (at an additional cost of ?20). Only if your optician has recommended bifocal lenses should you order them from us. Please ask your optician to make out your prescription assuming your glasses are worn 12-13mm from the eye (ie the back vertex distance)

The standard size is D28 - these are 28mm wide 'D' shaped segments that are positioned 3mm below the centre of the lens vertically and they are centred on your pupillary distance horizontally. Should you require them to be positioned further up then please state this on your order. D35 bifocal lenses (slightly wider) and Executive bifocals (these stretch across the full width of the lens) can also be ordered. If you would like either of these options then please just email us for a quote at

Yes. Your Optician will let you know if you are suitable for Bifocal (BF) Lenses. SpeckyFourEyes® recommends that you ask your Optician to make out a prescription for your glasses assuming that they are worn 12-13mm from the eye (the BVD or Back Vertex Distance).

We offer both single vision lenses and bifocals. We only supply bifocals to customers whose optician has recommended them. To all others, our standard single vision lenses will be suitable.

Implants are made of commercially and medically pure Titanium. This is the same metal that has been successfully used in hip implants for many years. It is inert and is not known to cause any type of rejection phenomenon. Dental implants have an 85-95% success rate.

Your dentist will make sure that the implants won’t show during all normal movements of the mouth and lips. You will need to be able to see them, so that you can clean them properly.
