Colored lenses sold online or in stores without a prescription may be bad for your eyes- their origin, sanitization process, contents, and sizing are often unknown. It's not legal to sell contact lenses without a prescription in the US for the protection of consumers. Prescription lenses with color still "breathe" less than clear lenses and are less comfortable if the paint is sprayed on the front surface. My preferred are Air Optix Colors because they allow the highest oxygen transmission to the eye and sandwich the pigmented layer in the middle of the lens- for a smooth, comfortable surface. I hope this helps!

There are literally dozens of drops to treat dry eyes AND itch is often a symptom of allergy- for which there are antihistamine and mast cell stabilizing drops as well! I recommend you see a doctor to determine which drops are best for the type of dry eye or allergic response you're experiencing. It takes a microscope and diagnostic dyes, meibography or special imaging to answer this question.

An oculoplastic surgeon would evaluate this and start with a CT scan to
answer your question regarding orbital reconstruction.

Yes, and sunglasses are always recommended to prevent skin cancer of the eyelids, growths (like pinguecula or ptyergium) on the eye, cataracts, and macular degeneration- besides improving your comfort and safety.

It sounds like you need to be examined by a doctor with a microscope- including the underside of your eyelids.

Your prescription is minimal. If the glasses make it worse, I would return to the prescriber for a recheck.

No.
