Careprost 0.03% is an ophthalmic solution used to lower the pressure built within the eye and is known as intraocular pressure (IOP). Careprost is used to treat glaucoma that is caused when fluid (aqueous humor) is build up in the eye. The increase in IOP can lead to the optic nerve fibres which may cause a gradual loss of sight. Careprost 0.03% can increase the drainage of aqueous fluid out of the eye causing a decrease in IOP and preventing loss of sight. These eyelash growth products also help in treating ocular hypertension to lower IOP. They also help in treating hypotrichosis that can be possibly caused due to abnormal eyelash growth. So, they help the consumer to grow longer and thicker eyelashes.
