Does Glaucoma Affect Nearsightedness Or Farsightedness
It doesn't: The eye color is determined by the pigmentation of the iris. The intraocular lens is placed behind the iris after removal of the cloudy lens (cataract). When you are looking at (or through) the lens, you are seeing the pupil of the eye, which appears dark. Some types of lens implants can cause some reflections or glistening appearance, but they do not change eye color. ...Read moreSee 3 more doctor answers
Sometimes: The focus of the eye is greatly affected by the lens - diseases such as cataract and presbyopia can dramatically affect the focus. Sometimes corneal scarring may induce astigmatism and keratoconous may cause irregular astigmatism requiring contact lenses to treat. ...Read moreSee 2 more doctor answers
It does not cause it: Just like within the body there are many parts, although one organ, the eye is very similar with many parts as well. Where floaters occur in the eye is separate from the area where the effects of glaucoma occur, which is the optic nerve. Floaters are typically black spots that appear real like gnats in front of you. Vision loss from glaucoma is like dark patches in vision that don't go away. ...Read moreSee 2 more doctor answers

Vision changes: Many ways, but fluctuating sugars can even blur vision just due to osmotic changes in the lens from sugar byproducts. Retinal hemorrhage and edema can also decrease vision. Cataracts form faster. Regular eye exams are key to preventing vision loss. ...Read moreSee 4 more doctor answers
Not at all: Glasses are like crutches - their job is not to heal you, only to help you with what you've got. The eye's prescription is essentially a product of its shape; glasses correct the prescription caused by the eye's shape, but do not cause the eye's shape to change for the better or for the worse. In young children there is a possibility of worsening vision from not using glasses, however. ...Read moreSee 1 more doctor answer
Need more correction: Hyperopia can be compensated by accomodation of your natural lens when you are younger. As you age this becomes less effective and by age 52 is lost. This means that you may need increasing lens power through the 30's for distance vision and by age 40 will need extra help (bifocals) at near. ...Read more
Refractive error: These are the names of different refractive errors. For clear vision, light must be focused by the eye onto the retina. Myopia, or nearsightedness, is when the eye focuses light in front of the retina. Hyperopia, or farsightedness, is when the eye focuses light behind the retina. Astigmatism is when light does not come to one focal point but is spread over a range. ...Read moreSee 2 more doctor answers
A little bit: The motion of the iris against the underlying fibers that support the lens (zonules) rubs off the pigment from the back of the iris which is the basis for pigmentary dispersion. A little bit comes off with everyday normal use and it can be accelerated with athletic pursuits. As long as your ophthalmologist feels that the internal eye pressure is not being increased, this is ok. ...Read more
Depends on severity: The child with cataract needs to be examined by the pediatric ophthalmologist. Congenital cataract is one of the cause of ambylopia. The best option for majority of the congenital cataract is cataract surgery and vision correction very early to avoid ambylopia. Visual development is very crucial in the early childhood. The child needs clear media to see and develop his/her visual pathway. ...Read moreSee 1 more doctor answer
