Single vision, bifocal or progressive: which lens is yours

Three kinds of lens, three ways of seeing near and far. How to work out which one suits your day.

Most people under 40 need only single-vision lenses. The whole lens carries one prescription, for distance or for reading, and it is the simplest and cheapest choice. Single-vision lenses start at ₹1,200 a pair at Nazar.

After 40, the eye’s lens stiffens and near work gets harder. If you already wear glasses for distance, you now need two prescriptions. A bifocal puts the reading part in a small window at the bottom of the lens, with a visible line. It is sturdy and easy to get used to, but the jump between distance and near can feel sudden, and middle distance, such as a computer screen, is not covered well.

A progressive lens changes power smoothly from top to bottom, with no line. You look straight ahead for the road, slightly down for the laptop and further down for your phone. Progressives start at ₹6,500 and take one to two weeks to get used to. They suit people who move between distances all day, such as teachers, shopkeepers and office workers.

Some people choose two pairs instead: single-vision for driving and a separate pair for reading. That costs less than one progressive pair and works well if you do not switch often. Our optometrist will ask how you spend your day before recommending one, and you can try sample lenses in the testing room.
