Medical Forum / General / Vision / June 2006Weak prescription - contacts suitable?
Hi all, I have a fairly weak prescription, but at the same time find my glasses help when driving, particularly at night. It is: L: -0.25 Cyl -0.75 Axis 172 R: -0.25 Cyl -0.5 Axis 30 Is this too weak to be considered for contact lenses? Also are toric lenses as effective on lower powered cylinders like this? Or would I be better off with a higher power Sphere to compensate? Again at these low powers is a CL prescription likely to be roughly the same as glasses or in general does the power increase/decrease for C/lenses compared to glasses? Thanks for any advice Steve > Is this too weak to be considered for contact lenses? > Also are toric lenses as effective on lower powered cylinders like this? > Or would I be better off with a higher power Sphere to compensate? People with your prescription sometimes try contacts and decide it isn't worthwhile. In a nutshell they say their vision "isn't bad enough". Both your myopia and your astigmatism are "borderline". Ask your practitioner to train you with a pair of -050 sphere lenses, to see if you tolerate contacts at all. Sphere contacts will be ~80% as good as glasses during the day, and you could wear glasses for night driving, or get toric lenses for the right eye. -MT > Hi all, > [quoted text clipped - 17 lines] > > Steve Are there any CLs available for a Cyl. of -.25? The lowest I found was -.50. thanks >> Is this too weak to be considered for contact lenses? >> Also are toric lenses as effective on lower powered cylinders like this?
