What do you suggest if my eyes seem to have become lighter in shade is this possible?

Changing eye color: Eye color depends on the concentration of pigment granules. Eyes tend to change color as we age.Slight color changes are a normal and harmless part of the aging process, but dramatic changes may indicate an underlying health problem. Ocular diseases which can cause color change are Horner's Syndrome, pigmentary glaucoma and Fuch's heterochromic iridocyclitis. As with most diseases, they are best caught early, as damage is most often irreversible. A visit to the eye doctor is recommended.
