Optical correction using glasses or contact lenses is the most common treatment; other approaches include orthokeratology, and refractive surgery. [68]: 21–26 Medications (mostly atropine) and vision therapy can be effective in addressing the various forms of pseudomyopia. Compensating for myopia using a corrective lens

[1] Early on there are often no symptoms. [1] Over time, however, some people experience a gradual worsening of vision that may ...
If is a root system, the Dynkin diagram for the dual root system is obtained from the Dynkin diagram of by keeping all the same vertices and edges, but reversing the directions of all arrows. Thus, we can see from their Dynkin diagrams that B n {\displaystyle B_{n}} and C n {\displaystyle C_{n}} are dual to each other.
