| The market for ophthalmic lenses represents: |
|
 between 9 and 9.5 billion euros. |
| between 850 and 950 million lenses each year. |
| a 90% renewal rate. |
| a periodicity of 3 years. |
|
|
| Each year, the corrective lens market grows by an average of |
|
| 0 to +2% in terms of volume |
| +3 to 4% in terms of value |
|
| |
A low lens adoption rate and the substitution between products of different generations make ophthalmic optics a promising sector.
Another source of growth is the ageing population. As of 45 years of age, all individuals start to show signs of presbyopia (difficulty adjusting) and require reading glasses.
