Hi Jialat,

I just went for an eye check and got my glasses changed. My new powers are:

L -4.75/-1.00/35
R -4.75/-0.75/155

It was suggested that I get contact lenses of the power below:

L -4.50/-0.75/40
R -4.50/-0.75/160

My old contact lenses (Acuvue Moist for Astig) are of this powers:

L -4.75/-0.75/60
R -4.75/-0.75/160

Question:
1) Can I still use my old contact lenses?
2) I don't use contacts very often, they make me dizzy and it is uncomfortable. What is causing this? has it got to do with the power or the type of lenses?

TIA!

Are you an optometrist? Do you sell contacts lenses? How much do you sell?
