Hi Sophielee, please don't worry but do either see your GP or an optician about your dry eye. It's important to get expert advice on this. I've been on artificial tears for nearly 30 years - Viscotears, Hylo Forte, Clinitas & now Optive Plus & I'm currently seeing an Ophthalmologist after referral from my optician as the dryness has worsened markedly since BSO. It's important that any eye drops used daily long term don't contain preservative.
The tears are produced by the lachrymal glands but the Meibomian glands (in the eyelids) also produce an oily layer that protects the tear film & prevents it evaporating too quickly. If the Meibomian glands are not working well then relief from artificial tears may also be only fleeting. MGD (Meibomian gland dysfunction) is fairly common as we age. The oils the glands produce tend to thicken & clog the outlets close to the lash line. An Ophthalmologist can examine you & test to see how well the various glands are working & prescribe appropriate treatment.
As Annie said, the Blephasol range can help to keep the lids clean. This has been recommended by my Ophthalmologist along with use of a heated eye mask twice daily to liquify the oils, followed by a massage technique to express them. If you Google MGD there are online videos about it.
There's some evidence that counter-intuitively, the oestrogen in HRT may make dry eyes worse & androgen deficiency may be behind dry eye & Meibomian gland dysfunction, but the relationship with sex hormones seems to be very complex. There was a study showing that women with DES on oestrogen-only HRT fared worse than those on combi oestrogen-progestogen, but surprisingly perhaps, that women on no HRT fared better than either of the other groups. Unfortunately I can't find the link! If there is a link between declining androgen levels & the development of DES then the finding about combi HRT makes some sense - if the progestogen was one of the more androgenic kinds. There's an interesting (but rather long) link here for anyone technically minded!
https://onlinelibrary.wiley.com/doi/full/10.1111/cxo.12147I'm currently trialling testosterone in hope it will help my dry eye condition among other things, but have also been referred for investigation for Sjogren's which causes systemic dryness.
Please do get it checked out.
