Could gene changes have any phenotypal (sic?) affect, at least theoretically, on something such as a person's eyecolor? How about on their offspring's?

Gene therapy inserts the correct gene into your organism (usually by being put into a virus that has been modified in order to be safe). That gene produces the protein that your gene can't produce, so it "eliminates" the sickness. But the DNA in your cells doesn't change. The correct gene just corrects the defective one that you possess. And since the genetic material remains the same, the improvement is temporary, for as long as you follow the therapy and it can't be transferred to offsprings.

DNA is a constant factor in the genetic molecules an individual.. it's like a blueprint or thumbprint.
Gene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, and hereditary diseases in particular. Gene therapy typically aims to supplement a defective mutant allele with a functional one. Although the technology is still in its infancy, it has been used with some success.
In the 1980s, advances in molecular biology had already enabled human genes to be sequenced and cloned. Scientists looking for methods of easily producing proteins — such as insulin, the protein deficient in diabetes mellitus type 1 — investigated introducing human genes to bacterial DNA. The modified bacteria then produce the corresponding protein, which can be harvested and injected in people who cannot produce it naturally.
It's possible to change DNA via genetic enginering. This involves manipulation of genes. That's why this field is very controversial
Because of the vrarious ethical issues involved. All experimentations are squashed even before they are started. So the future of this right now remains to be seen.

gene therapy is usually related to correcting disease caused by mutation in genes.
genetic engineering is used to alter dna for the purpose of changing something about the organism (example: eyecolor)

it all depends on the persons genotypic ratio. for example if a heterozygous domimant mates with a heterozygous ressesive the offspring will have all dominant traits but his/her child will be able to have a ressesive traited baby. ex. Eyecolor BB mates with bb the offspring will have Bb then the next time this person mates you can have BB,Bb,bb.

Not with any present day science or medicine.
The idea has been submitted by various science fiction writers.

You can't change the natural pattern of dna. However, you can change the chances of genes.

many environmental effects get groomed in genotypic? for off-springs
