Meanwhile many eye problems due to rosacea, especially watery eyes and red eyes. Rosacea has several styles, phymatous rosacea and ocular rosacea are two of them. Both of this two styles do harmful to our eyes deeply, my brother-in-law added, ocular rosacea ranks first. People who have ocular rosacea may feel sensitivity to light, even eye itching and burning, what's worse, blurry vision and loss of vision can occur gradually. So you'd better accept a medical treatment and avoid factors which affect rosacea. It is said that sun exposure, emotional stress and hot weather can make your rosacea much worse.
