I'm not sure but hard lenses, at least the ones I remember, are more permeable in terms of oxygen being allowed to pass through than soft lenses. however, hard lenses are more susceptible to being dislodged by any slight physical knocks to the facial area. this is not a good thing if you're wearing it for the purposes of sports. if so, soft lenses would be a much better idea.
also, if you had to custom make disposables, I would think $400 is reasonable. that was the approximate amount I had to pay for a 13 month supply (12 month paid, 1 month "sample"). again, it has been a while (about four years now) since I last paid for contacts so I might be a bit rusty in the pricing department.
