P.R.
I've worn contacts for about 25 years, both soft and hard. I've had trouble with dryness and with allergies to some brands of soft contact lenses, often getting conjuntivitis. I needed lenses I could replace often but the cost seemed too high.
I tried hard (gas permeable) lenses for a while; they are smaller than regular contact lenses and use a gel like cleaner. I did Ok with them but costwise, they can be really expensive if you lose one. I found that if I got stressed, they would just pop out as well.
After talking with my eye doctor (an opthamologist and eye doctor), he suggested Acuvue 2 disposable lenses. He explained that they do not need to be used as marketed (wearing them all the time and then throwing them out after a couple of days) as this was a marketing gimmick that makes these inexpensive but less durable lenses more profitable for the manufacturer.
What he suggested is that I use the Acuvue 2 lenses the same way as regular soft contact lenses - taking the pair out each night, cleaning them with Renu cleaner, and letting them soak overnight. If you do this, the Acuvue 2 lenses last you about 2-3 months per pair, pretty much until they tear. They are extremely comfortable, you'll forget you're wearing them.
With these lenses, you do not need to use the protein-dissolving tablets for deep cleaning as you replace the lenses a lot more often.
I have since checked with two other ophtamologists and they agreed that it was Ok to do this.
Another great tip - get the contact lens prescription from your eye doctor (make sure it's an ophtamologist, not an optician from an optic who is not as well trained and whose exam would not be as thorough). Then, head over to Costco - you can get one or more boxes (6 lenses each) for a fraction of the price and, if over time you find these work for you, you can stock up and get back $20 rebate. Costco also sells 2-pack Renu for a fraction of the price.
Even if you buy the Acuvue 2 at retail - Walgreens sells a box of 6 for $22, the cost per lens is still less than $4. If you got through 4-6 pairs per year, that still only about a $44/ year investment for the lenses (if worn daily wear, not extended).
You can also ask your doctor for your prescription for eyeglasses when you have your eye exam done for lenses - it's good to have as a backup. You can find a great selection of designer styles at Costco with thin scratch-resistant lenses, and they'll cost about half of what a regular optic such as Lenscrafters or Pearl Vision charges.
