• Is it hard to get vision insurance if you already have glasses?

  No, it is not like that. If people wearing glasses can't apply for vision insurance, there is no point for it. Vision insurance only covers the cost of an annual eye exam and glasses/contacts out over the course of a years premiums. They wont even ask you whats the problem with your eyes when you apply for it.

• Are there extended wear contacts for astigmatism?

  Yes. There are a wide variety of contact lenses available for astigmatism, including hard, soft and extended wear. You can go to your nearby optical store to ask. But extended contacts are not always safe to wear although they are designed for long time wearing.

• Why does eating carrots improve night vision?

  Rhodopsin is important in color detection. Light-sensitive, purple-red organic pigment contained in the rod cells of the retina that allows the eye to see in black and white in dim light. It is composed of opsin, a protein, linked to retinal, a conjugated molecule (see conjugation) formed from vitamin A. So eating carrots which are high in vitamin A can help improve night vision. source? http://wiki.answers.com/Q/How_do_our_eyes_see_color#ixzz1vUUWr0S5

• What is the ophthalmoscope used for in an eye exam?

  Ophthalmoscopy is done as part of a routine physical or complete eye examination. It is used to detect and evaluate symptoms of retinal detachment or eye diseases such as glaucoma. In patients with headaches, the finding of swollen optic discs, or papilledema, on ophthalmoscopy is a key sign, as this indicates raised intracranial pressure (ICP) which could be due to hydrocephalus, benign intracranial hypertension (aka pseudotumor cerebri) or brain tumor, amongst other conditions. Cupped optic discs are seen in glaucoma. In patients with diabetes mellitus, regular ophthalmoscopic eye examinations (once every 6 months to 1 year) are important to screen for diabetic retinopathy as visual loss due to diabetes can be prevented by retinal laser treatment if retinopathy is spotted early.

• How long does it take to get used to hard lens?

  It does feel uncomfortable when you first wear hard contacts. You can try to increase the wearing time like 15 or 30 mimutes or day by day, but don't make big jumps, then you should wear them longer.

• Are color blind people able to see at night?

  Yes, color blind people can still see things at night. the lack of color vision should not effect the ability to see in the dark. But the world in their eyes is gray.

• What are the risks of wearing Extended Contacts?

  Although extended contacts are designed for long time wearing, it is still not always safe to wear them. Extended contacts still need to be cleaned regularly and if not, the opportunity for growth of bacteria would increase, which can endanger the health of the eye.

• Is it normal for astigmatism contact lenses harder in the middle than the outsides?

  YES, it is just that type. Lenses for astigmatism ( toric lenses) are all like that. I think they are more easy to wear than regular soft contacts as they are harder in the middle part.
