Close-up lenses: with them we can see clearly at distances between 33 and 45 cm. They are usually designed for specific tasks such as reading and sewing. They do not allow good vision at other distances.
Bifocal lenses: through this type of lens we can see well both from afar and up close, but not the intermediate distances (distance from the computer). It is an option that is already in disuse especially due to the fact that they are not very aesthetic.
Occupational lenses: these are lenses through which we can see perfectly clear intermediate distances and close distances. They are specially designed for people who work for long hours in front of the computer and with documents in near vision.
Progressive: it is the most versatile solution. They are lenses that have several focuses of vision (multi-focal) in the same lens, thus progressively passing from the distance to the intermediate distance, and from this to the near distance. This type of lens allows clear vision at all distances. There are also progressive contact lenses, with the same visual advantages.
Surgical correction: it is not a solution that is performed in optical centers. Corneal laser surgery and multifocal intraocular lens transplantation stand out.
