Generally, any lens can fit into any frame. However, opticians must take into consideration the prescription they are working with as this will help them to determine how thick or thin the lenses can be.
It will also help them to determine the design of the lens they will need to use. opticians will then have to consider the design of the frame, is it rimless? Semi-rimless? Full rim or inline glazed frames? All of this will help them to advise what material lens they need to use, as some lenses have elastic-like properties and therefore would be better suited to rimless glasses for example. Some stronger prescriptions may need high-index thin lenses to achieve the best results.
How will you use the glasses?
Opticians would also need to consider how the wearer will be using their glasses, so in the case of needing glasses for distance and near-vision work, they would need to bear in mind the working area so they can then advise on the correct bifocal, varifocal or occupational lenses.
In cases of working with mild prescriptions, lenses may need to be manufactured individually, to thicken them up so they can be glazed securely into the frame.
Different types of lenses
There are also different lenses which can help enhance the look and performance of the glasses too. From reflection free lenses to transition lenses which are photosensitive so change colour to protect your eye from UV and brightness.
A number of independent practices will offer a variety of options on lens technology from standard lenses to lenses that can give you HD vision. From fashion frames, traditional styles, children’s frames, specialist frames, sports frames and safety glasses.
