What are Progressive Lenses?
Progressive lenses, also known as multifocal lenses, help people see objects that are up close, in the middle distance, and far away. If you have trouble reading a road sign, get headaches whilst doing computer work, or find yourself squinting at your phone, progressive lenses may provide a solution.
They work by combining several prescriptions into one lens, so you don’t need to swap between glasses to see different distances. Progressive lenses are a common form of vision correction for people who have age related eye deterioration, often starting when they enter into their 40s and beyond. They are also an increasingly popular form of vision correction to help control shortsightedness amongst school aged children.

What are progressive lenses
Progressive lenses (also known as no-line bifocals) are multifocal lenses. They are designed to help people who have trouble with both near and far vision, as well as intermediate vision. Progressive lenses combine the three prescriptions that you need to treat these vision problems, all within the one lens.
At Oscar Wylee, we offer a range of lenses, including progressive lenses, so you can check your texts (close-up work), do your computer work (middle-distance work) and drive to the shops (far distance work), all with the same pair of glasses. We also have a range of lens indexes available, including high index lenses , so you can pick how thick your lenses are.
Progressive lenses vs bifocal and trifocal lenses
Progressive lenses are unique from other bifocal or trifocal lenses as they do not have a visible line separating each prescription or lens power. A bifocal lens for example has two prescriptions to assist with near and far vision, separated by a visible line. Similarly, a trifocal lens has three prescriptions, and two corresponding lines to separate each prescription. The transition from each prescription within a bifocal or trifocal lens is distinct.
Progressive lenses do not have this visible line nor are they broken up into these rigid sections. Instead, the prescriptions in a progressive lens are blended together, allowing for a smooth transition when switching between far and near vision.
Single vision lenses vs progressive lenses
Unlike progressive lenses, a single vision lens has just one prescription. This means that if you have trouble seeing things in the distance (nearsightedness) or close up (farsightedness), you will need two pairs of glasses, as there is only one prescription per single vision lens. An example of a single vision lens is our Oscar Wylee reading glasses. These glasses have one prescription over the whole lens, for near work only.
How do progressive lenses work?
Progressive lenses aim to correct both nearsightedness and farsightedness, whilst also helping with middle distance vision issues. They do so by combining three prescriptions into one lens. The top of the lens is powered to help you view long distances clearly. The middle of the lens helps you to see at an intermediate distance, and the bottom section helps you to see close up.
The progressive lens is designed without a visible line separating each prescription. This means that there is a gradual shift in the strength of the lens. You can write a text on your phone, then glance up at the television, and the change in distance vision will be smooth.
The pros and cons of progressive lenses
Everyone’s eyes are different, so the corrective glasses that we need to help with vision issues will vary from person to person. This is especially applicable in the case of progressive lenses. Whilst these lenses are revered by some, for others they are too hard to get used to and end up being the wrong choice. It is important to assess the pros and cons of progressive lenses, and talk through your decision with your Oscar Wylee optometrist and dispenser, before deciding to purchase.
Benefits of progressive lenses
Progressive lenses have a range of benefits from vision correction to convenience considerations. Progressive lenses are effective in treating a wide range of eye conditions, including far and nearsightedness. They can also help those with astigmatism. Progressive lenses are effective in treating presbyopia, an age related condition in which the eye struggles to focus on objects, specifically close objects.Source: Good Vision for Life.
Another major benefit of progressive lenses is their convenience. With three prescriptions all on the one lens, you do not need to switch between several pairs of glasses.
Progressive lenses disadvantages
A major disadvantage with a progressive lens is how hard they can be to adjust to. One of the main reasons for this is what’s referred to as “soft focus”. Through the central corridor of the lenses, starting from the top (distance prescription) running through to the bottom (near prescription) is where you will get the best vision. The further away you look from this corridor, the more distortions, or soft focus, you will notice. The wider this corridor, the larger the area of clear vision and the easier it is to adapt to.
Other common problems
Nausea and headaches are some of the most common problems people face when first using progressive lenses. Dizziness may also occur along with blurred vision. Whilst most find their vision eventually adapts, many people will have increased difficulty adjusting to progressive lenses. For these people, progressive lenses may not be the right choice.
