Therapeutic spectacle lenses are most often used by school aged children, university students or people working in offices that are measured to have a degree of visual stress or inefficiency.
These lenses are not to be confused with compensating lenses which are typically what people think of when they think ‘glasses’.
That is, compensating lenses reduce blur whereas therapeutic spectacle lenses are used to reduce symptoms such as sore eyes or headaches or intermittent blur that may result from visual inefficiency conditions such as convergence excess, convergence insufficiency, accommodative excess or accommodative insufficiency.
The most effect means of prescribing involves a type of multifocal lens, this allowing the therapeutic benefit at near to be achieved whilst not interrupting a person’s distance vision. It is important that children usually be prescribed this type of lens to best function in the classroom.
