I use daily disposable contact lenses as my eyes never tolerated monthly or weekly lenses. I have tried a few different brands -- Focus Dailies AquaComfort for quite some time, and then Acuvue TruEye when my eyes were consistently bloodshot with the Dailies. I ran out of TruEye and have attempted reintroducing the Dailies simply due to the expense of TruEye.
1. With the Dailies, my main issue is irritation at the medial aspect of my lens, which seems to cause a rippling effect to the contact. Is that due to the eye becoming bloodshot/irritated -> rippling? or vice versa? or is it related to the shape of my lens and poor fit?
2. With the TruEye, I had no issue with bloodshot eyes or rippling, but the lenses consistently felt loose or mobile on my eye, and in fact one fell out of my eye on one occasion without trauma/cause.
Are both of these issues related to the shape of my lens and I may just not tolerate contacts?
It does sound like an issue with the fit. Daily lenses tend to come in a one size fit all design and may not suit everyone. It may be worth trying other daily lenses to see if the fit can be improved. Ask your practitioner if you can try some other designs. Among the Specsavers range you could try Easyvision daily Umere or Clearus.
