Need help with contact lenses?
I have been wearing Cooper Vision Encore Premium contacts lenses for 5 years now. The script has always been at -2.25 for both eyes. A while ago, I switched from the Cooper Vision lenses to the new Air Optix Aqua lenses but the script is exactly the same.
Since I switchd brands, I feel dizzy when wearing the Air Optix. So my question is.. even though the script is the same, can switching the brand of lenses make a difference in vision?
It may take a while for your eyes to get used to the new contacts but if doesn't get better by next week stop wearing them and see an contact specialist.
