What happens to my eyeglass lenses overtime?

I buy replacement eyeglass lenses from an online company using my old frames and 1.67 Super Thin High-Index Lenses. After about a year of use the lenses suddenly get splotchy and clouded. I use only a soft cotton cloth (an old t-shirt) to clean them. It's not scratched. I don't get any anti glare or scratch resistant coatings applied when purchasing a new pair. I've used 2 different companies with the same result.
Am I doing something wrong or is one year the life expectancy of 1.67 Super Thin High-Index Lenses?
