What Are Varifocal Glasses?
Varifocal glasses, also known as varifocals, varifocal lenses, PALs, or progressive lenses, have a gradual change in strength from the top of the lens to the bottom with multiple focal points in between. This allows you to see all distances and focus points through just one lens. Varifocal lenses are typically used when you have two prescriptions, one for distance and one for reading.
There are three regions of a varifocal lens which are distant zone, intermediate zone and, near/reading zone. Usually, the upper portion of the varifocal lens is the distant zone and the bottom portion of the varifocal lens is the near or reading zone.
One of the benefits of varifocal glasses is that you do not need to prepare 2 separate pairs of glasses or need to switch between frames for different vision needs.
The nose pad is very important.
It could be that the nose pad is too hard. You can replace it with a non-marked soft nose pad. It is recommended to choose a thin and long or broad-leaved nose pad, moderate hardness, which can effectively disperse the force of the nose, with stable support, bringing comfortable wearing. It avoids a soft nose pad on the bridge of the nose because of sweating or a long time to wear left indentation. Eyeglass frame nose pads are in direct contact with the bridge of the nose, and too hard nose pads can damage the skin around the bridge of the nose. Therefore, try to choose a silica gel nose pad and other soft materials. The first one is that the silicone has good softness and will not damage the skin. The other is that it can fit perfectly with the bridge of the nose without foreign body feeling.
