Bimat eye drops are used to treat hypotrichosis, short, weak eyelashes. Bimat increases the length, thickness and enhances the color of eyelashes. These substances are also used to lower intraocular pressure in patients with a diagnosis of glaucoma. By reducing the pressure, the risk of blindness is significantly decreased.
These drops gained immense popularity, demonstrating an incredibly fast and always noticeable result since its application. This innovative means will allow you to give your eyelashes an ideal look, strength and health, in whatever serious condition they are before the moment of its application. It is safe and effective providing amazing results.
This means is prescribed to reduce eye pressure. Its active ingredient is synthetic prostaglandin bimatoprost – an unsaturated fatty acid, similar in its properties to hormones. Getting into the eye, drops help maintain the balance of the flow and outflow of eye fluid. It is a violation of this balance that leads to an increase in pressure, due to which the blood supply to the eye is impaired and the load on the optic nerve increases.
Bimatoprost reduces IOP in humans by increasing the outflow of aqueous humor through the trabecular meshwork and uveoscleral outflow. IOP reduction begins about 4 hours after the first use. The maximum effect is achieved after about 8–12 hours. The effect lasts for at least 24 hours.
