I didn't want to hijack the recent thread on astigmatism, but thought I'd share my hard won experience of contacts for cricket, in case it might be of use to somebody.
Although in day-to-day use glasses give me better vision than contacts, I found the advantage off-set by misting, sweat dripping on the lenses, and them slipping at the least convenient moment.
When I switched to contacts, they would dry out in the sun and wind, leaving me with blurred vision and desperately blinking as 5 3/4 ounces of high velocity leather flew straight at my delicate parts. So, I reasoned that what I needed was lenses with a high water content to counteract the drying. What followed was trial after trial of each manufacturer's version of 'moist' lenses - which are becoming more and more popular, as (I believe) they allow more oxygen to reach the surface of your eye and are therefore healthier. Eventually I met an enlightened, cricketing, Saffer optician [oxymoron?]. He opened my eyes, and I have seen the light! What I needed was low water content, as there was less evaporation and my de-hydrated eyes didn't have to work so hard to compensate for the loss of moisture. I eventually settled on CooperVision TruEye, and I haven't looked back since; as it were.
The only other thing to say is that, as I have moderate astigmatism in both eyes (which is what brought me to the previous topic), I find that I need to wear them, at the very least, from when I first get up on the morning of a game, so that my brain can make the adjustment from glasses. It is certainly hopeless if I put them in just before a game, and is preferable to have worn them the day before.
I hope this helps you (and my Panamanian held investments in CooperVision).
