Product description of Timolol eye drops:

This lessens the quantity of aqueous humor that is formed into the eyeball by the ciliary body. Timolol also blocks beta-receptors present on the blood vessels that supply the ciliary body. This causes the blood vessels to narrow and reduces the inflow of aqueous humor into the eyeball resulting in the lowering of raised intraocular pressure.
