Have you ever bought top of the range High Index Lenses but still ended up with an unsightly pair of glasses with lenses that either stick out at the edge or are very thick in the centre? If you are short sighted and have a strong minus prescription your lenses will be thicker at the edges than in the centre. It is the opposite for those of you who are long sighted and have a strong plus prescription, your lenses are thicker at the centre.
Most people do not realise that when you have a strong or complex prescription as well as choosing the correct high index lenses, it is just as important to select the right type of frame. This way you will you end up with a pair of glasses that you will be proud to wear.
Here are a few simple tips that will help you choose the right type of frame:
The Right Frame makes all the difference
- Choose a fully rimmed frame. Rimless or semi rimless frames leave either part or all of the lens exposed, making it easy to see exactly how thick your lenses actually are. A fully rimmed frame covers all of the lens and therefore helps to disguise the edge thickness.
- Try to choose a Plastic frame rather than a metal one. Plastic frames have thicker rims which help to disguise the edge thickness better.
- The most important factor is to choose a frame with a smaller lens diameter. If have a strong minus prescription your lenses will be thicker at the edges than in the centre. Choosing a frame with a smaller lens diameter will reduce the total surface area of the lens and make the edges thinner. If have a strong plus prescription your lenses are thicker at the centre, so a frame with a smaller lens diameter allows us to make a smaller blank which will reduce the centre thickness of the lens.
- Simply choosing a frame that is a few mm smaller will have a dramatic effect on how your glasses will look. Not only will they cut down the edge thickness if you are short sighted but will also reduce the centre thickness for those of you who are long sighted.
- Whilst choosing a frame with a small lens diameter is important, you still need to ensure that it fits you comfortably. The ideal lens diameter for most women is between 47- 49mm and between 50 – 52mm for most men. Check your existing frame to see what size it is. They are usually displayed on the inside arm or across the nose bridge e.g. 49-17-135 ( where 49 refers to the lens diameter, 17 refers to the nose bridge and 135 refers to the arm length).
