Depending on what caused their blindness and how much damage was caused, yes. Injuries such as detached retinas and conditions like cataracts can cause blindness, but are sometimes reversible through surgery. Diseases like glaucoma can also cause blindness, but be treated with some medications.
Generally, a blind person blinks for the same reason a sighted person blinks. We blink to maintain the moisture in our eyes. They're at the same rate.
Blind children and blind adults who have never been sighted before, are often seen moving their heads back and forth. This is a mannerism that they do because it helps to stimulate them. They don't know that sighted people don't do it because they have never seen it done before.

No... fortunately as we blink so often!
I am not a blind person although I do have some blind friends, so I have some insight into the psychology of the blind. Blind people, much like sighted people, are not all the same, and do not all have the same criteria for dating. Some blind people would be quite happy to date someone who is ugly but friendly and who has shared interests (for example, science fiction fans often like to date or marry other science fiction fans). But appearance can still matter. A blind person may wish to have children, and if so, he or she would normally prefer that his or her children will be good looking. So the appearance of a spouse, which will be part of the genetic inheritance of the children, will still matter, even if the blind person never actually sees that appearance. How would a blind person know what is ugly, and what isn't? I don't think they would care too much since they can't tell who is attractive, and who isn't.
Well as people think bats are blind because they often bump into people they acually see better than people. As people thinking bats were blind for many years people used the phrase even after science proofed bats weren't blind! They told it to people who were clumsy or needed glasses!
it is presumed that homers dissabillity is that he might be blind but people often said that poets where blind anyway
Unlike humans, cats have more effecient tear glands and ducts. Also, they need to see much more when they're hunting, and so they don't blink. They blink about every five minutes.
Having first had a blind schnauzer puppy (that died at 4 mos.), then a sighted schnauzer puppy, I can tell you my observation of the behavioral differences between the two. All puppies are different, but if you suspect yours is blind, it might be helpful to compare him to these two puppies.Our sighted puppy climbs over and around obstacles; our blind puppy would stop and give up.Our blind puppy bumped his head on the wall and on furniture often; our sighted puppy does this rarely.Our sighted puppy runs to his bed to nap, no matter if it has been moved; our blind puppy would lie on the hard floor unless placed in his bed.In a large space, our blind puppy walked in circles; our sighted puppy sees things of interests and heads straight for them.Our blind puppy walked with his nose to the ground, smelling as he went along; our sighted puppy looks straight forward.Our sighted puppy looks at us in the face; our blind puppy looked at us at our legs or torsos.Our blind puppy would sit or lie down in seemingly random positions, often facing the wall; our sighted puppy positions himself to see the goings-on.Our blind puppy would stumble upon his toys then play with them briefly; our sighted puppy finds his toys, picks them up, carries them around, then invests more time in playing with them.Our blind puppy walked along the sides of the hallway; our sighted puppy walks in the middle.Our sighted puppy actively explores all parts of our apartment; our blind puppy appeared to get lost behind the couch, under the bed, etc.Our sighted puppy looks directly at objects, even if they are motionless; our blind puppy appeared to look at general areas when sound came from them.Our blind puppy engaged people and other dogs by standing still, barking, bowing and touching them with his front paws; our sighted puppy walks up the them and examines them visually.Our blind puppy would often try to engage people or dogs after they had already left; our sighted puppy follows them or watches them leave.Our blind puppy would step unknowingly off edges of the vet table, off the top step of stairs, off the couch, etc.; our blind puppy stops at the edge and looks down.Our blind puppy encountered the bottom step of the stairs and acted as if it were a wall. When his front legs were manually placed on the step, he never made an effort to go up, never thinking there was anything beyond that step worth exploring.It may seem hard to believe that a pet owner would not be aware that a puppy is blind. Our puppy was blind since birth, but not diagnosed until 3 months of age. We did, however, suspect he was klutzy, dopey, dumb, retarded, mean, antisocial, aloof, etc. because of his behavior. We were embarrassed of his behavior. Once we found out he was blind, everything made sense. We compensated and accommodated. We told people and interactions went much more smoothly. We were deeply proud of our brave blind puppy and totally devastated when he passed away.Our sighted puppy seems more clingy and emotionally dependent upon us than our blind puppy was. The sighted puppy cries to be picked up; the blind puppy did not.When you know your puppy is blind, you will love him more. Your human instinct to protect those you perceive as weak and vulnerable will kick in.
Well, first their eyes might need to blink more so they don't get dry, or it could be Tourette's Syndrome. They often will shrug too often, get tics, and cough too often. If you are having any of these symptoms you may want to get this checked out. Hope i could help
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
