I'm a 20 year old female with fair skin. I recently used about a pea-size amount of 0.05% generic Retin-A on my undereyes, crow's feet area and eyelids nightly for about 3-4 weeks. Whenever I went out/drove, I used SPF 15 on the eye area, and usually sunglasses too. When I stayed at home, I had no SPF and the eye skin was exposed to soft sunlight from windows. I don't use sunscreen on the eyes now and wear sunglasses that wrap around my glasses. Have I permanently damaged my eye skin? Thanks!
Sunlight from Windows Causing Unprotected Eye Skin Damage?

You can get sunburns through glass windows
UVA light can penetrate through glass windows, so need to make sure to protect your skin even if you are driving or inside, but near windows. Make sure to choose a sunscreen or moisturizer with sunscreen that contain UVA blockers. Ingredients to look for include: avobenzone with octocrylne, mexoryl (trade name Ecamsule), zinc oxide, or titanium dioxide. While topical retinoids, such as tretinoin, can help improve the appearance of fine lines and wrinkles in the long term, you must be careful when you use them because they can make you more sensitive to the sun!
Retinoids and the sun.
There are two kinds of ultraviolet radiation that affect the skin: UVB and UVA. UVB (the one that causes sunburn) does not generally pass through glass whereas UVA (the one that causes skin wrinkles) does so with relative ease. The amount of UVA that passes through depends on the type of glass and coatings. Although skin treated with retinoids can be more sun sensitive, your use of retinoids is minimizing any damage caused by the UVA passing through the glass.
