If both you and your spouse have terrible eyesights and wear glasses, does that mean your children will inherit this bad gene?

According to research that I found, "if both your parents are nearsighted, then you have about a 1 in 3 chance of being nearsighted too. If only 1 of your parents is nearsighted, then you have a 1 in 5 chance of being nearsighted. If neither of your parents is nearsighted, then you have less than a 1 in 40 chance." To summarize, it would appear that there's a good chance that genetics has something to do with eyesight. http://genetics.thetech.org/ask/ask73
