Bifocals

Bifocal lenses contain two distinct prescriptions within a single lens. The upper portion is for distance vision. For driving, watching television, or viewing anything more than arm's length away. The lower segment (the D28 reading zone) is for near vision tasks such as reading books, menus, or smartphone screens.

Your eyes naturally learn to direct their gaze through the appropriate zone depending on the task.

Most new bifocal wearers adjust within a few days to a few weeks of consistent use. During adaptation you will learn to tilt your gaze, looking through the upper zone for distance and glancing slightly down for reading.

Common initial challenges include navigating stairs and judging distances when looking at the ground. Wearing your bifocal glasses consistently every day is the single most effective way to speed up the adjustment. If you genuinely cannot adapt, Direct Sight offers a free lens exchange within our 30 day return period.

Yes, bifocal glasses are safe for driving and widely used on UK roads.

The upper distance-correction zone provides a clear, unobstructed view of the road ahead. Always ensure your prescription is current before driving with any new glasses.

When you buy bifocals online from a reputable UK optical retailer like Direct Sight. You receive the same quality D28 bifocal prescription lenses as those sold on the high street. But at a significantly lower price.

Our lenses are manufactured to the same optical standards. Our £35.00 price point reflects lower overheads rather than lower quality. Our 365 day guarantee and free lens exchange policy underlines our confidence in the prescription bifocal glasses we supply.

To order bifocal glasses online you will need a valid prescription from an eye test that you have had within the past 2 years.  The prescription may include a sphere, cylinder and axis values.  You will need to provide these value where present along with your reading or near add value.  You will also need your pd value, the distance between your pupils.

Bifocal glasses can be used for computer work, though you may need to experiment with monitor positioning. The reading segment is optimised for close near-vision distances (typically 35 to 40cm). So you may need to raise your monitor or adjust your seating so the screen falls comfortably within the lower reading zone. However, intermediate vision is not their intended correction use.

For extended screen time a dedicated pair of computer glasses or progressive lenses are more suitable.

Yes, bifocal prescription glasses are typically more affordable than varifocal lenses in the UK. Varifocals require a more complex, bespoke manufacturing process with a graduated multi-zone design, which increases production costs.

At Direct Sight, our bifocal and varifocal lenses are competitively priced. With the D28 bifocal lenses start from just £35, compared to entry-level varifocals that start at £45. For wearers who only need distance and near correction (without an intermediate zone), bifocal glasses online represent outstanding value.
