Is your optician recommending varifocal lenses in your glasses, or are you wondering what they are? Varifocal lenses work by offering a gradual change in lens strength from the top to the bottom of the lens. There is no specific area of lens strength and the zones are progressive. The lack of a dividing line make varifocals look better visually and also remove the need to have several pairs of glasses.
When you have varifocals you need to look through them differently to standard lenses, depending on what you want to look at. If you are looking at something close-up you need to look through the bottom of the lens. If you want to look at something far away you look through the top of the lens. With practice you can vary where you look depending on the distance of the object you want to focus on.
When you first have your varifocal glasses you might have a few problems. This is very normal and happens to most people. The more you wear them and practice, the easier it will get. You will quickly get used to them.
Common Problems With Varifocals
Varifocals can cause problems when you try to focus on what you need to look at. Losing focus can cause dizziness and headaches, especially with tasks that need quick changes in near and middle distance focus like going up or down the stairs. Another common problem is experiencing a swimming feeling when you are walking. This is caused when you are aware of distortions in your peripheral vision and the reading part of the lens being at the bottom part of the glasses. To avoid this you need to try and not look down when you are walking along. Another issue is the need to move your head more often to see certain objects better. This can take some practice but it will improve over time.
How Long Does It Take to Adjust to Wearing Varifocals?
Everyone is different and it may take you anything from a couple of days to a few weeks to get used to your varifocals. Any new glasses can take time to settle down and with varifocals the brain needs to adjust to the new way you see things. It is really important to keep wearing your varifocal glasses even if you find it difficult. Your eyes and your brain will adjust if you give them the chance. Ask your optician for help if you continue to struggle. 98% of those with varifocal glasses adapt to wearing them quite easily.
