Dry eye disorder is often caused by androgen deficiency (restored by increasing testosterone)

[cs3000]

Androgens play a major role in keeping healthy eye & skin moisture,

TLDR;
Combined esterified estrogen and methyltestosterone treatment for dry eye syndrome in postmenopausal women - PubMed
(testosterone mainly, in this study the estrogen likely wasnt necessary and probably hindering) "Ten (91%) of 11 patients reported improvement in dry eye symptoms while receiving treatment. For these 10, relief occurred after an average of 4.1 months of treatment (SD 3.2, range, 1-9 months)."

e.g dry eye disorder is common post menopause when hormones drop

replacing hormones post menopause restores skin moisture , but
https://pubmed.ncbi.nlm.nih.gov/11451620/

replacing estrogen post menopause often isnt effective for helping dry eye disorder and may even worsen it ,
([Sex Hormones and Their Effects on Ocular Disorders and Pathophysiology: Current Aspects and Our Experience]
"The role of estrogen is not yet fully understood, but several in vitro animal and human studies show that estrogens decrease the secretion of the sebaceous glands, inhibit lipogenesis, and promote inflammation of the ocular surface"(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8949880/))

Higher E2 and lower luteinizing hormone (LH) were associated with worsening of dry eye symptoms (ρ = 0.34 p = 0.03, ρ = −0.49 p = 0.001). Reduction in LH and increase in progesterone (P4) were associated with increased ocular pain (ρ = 0.45, p = 0.004 and ρ = 0.39, p = 0.01). Dry eye symptoms were predicted by LH and tear break up

, even though low estrogen is correlated with dry eye disorder.
because testosterone levels also drop in menopause, and the low estrogen is a sign of low testosterone / androgens too

Sometimes progesterone helps probably by countering estrogens effects, so combo may be best

On a clinical level, in fact, there is an alteration in the functioning of the meibomian glands and an increase in the risk of DED in all cases in which there is a reduction in circulating androgens, a dysfunction or insensitivity of the androgen receptors, or anti-androgen therapy
Meibomian glands provide key components to the tear film that help maintain a healthy ocular surface. When meibomian glands function correctly, the lipids secreted reduce ocular surface water evaporation and prevent dry eye

some men get vision problems paired with dry eyes and skin issues as they get older and its largely because of this testosterone/androgen drop (in both genders)

so in many cases the cure is replacing the lacking androgens / fixing the lack. e.g Hypothyroidism might also play a role here, as enough thyroid hormone needed to stimulate STaR protein for testosterone synthesis

on the other side, in some cases tipping over to androgen excess can cause a blockage. something to be aware of, if taking high amounts and trying to fix eye issues which should only need a return to normal levels

Cool stuff. Poorly functioning eye muscle that stretches the crystal in the eye is the cause of poor vision. Muscles degenerate as testosterone falls.
