We don't provide that kind of service. JCH MD
Hello,
I want to order contacts online. My OD Cylinder is -4.00 but the drop box shows -3.75 and -4.25. There is no option for -4.00. So which do I choose?

Thank you for your kind advise and attention. My passion is running long distance. I felt frustrated that I can no longer run long distance. Running long distance has given inner piece and comfort. It also help regulate my blood pressure as I have high blood pressure ( 140/90 ). Unfortunately with retina, one cannot predict or feel if the retina is under pressure, unlike the muscle where we can feel the ache after running few hours which give you signal to slow down or to stop running, but with retina, we don't know if it is about to worn or torn or detached, or is there ? How to define strenuous exercise ? I read somewhere that an exercise is considered strenuous if the heart beat is above 70 % of ( 220 - age ). Thank you for your kind attention.
I have answered this question before either in a previous post or in a message you sent to me.
