Doctor insights on:
Plastic lenses: These are eyeglass lenses made of a plastic which will bend light more than the usual plastic . Because of this, a thinner lens is possible and has the advantage, being plastic, of being lightweight although somewhat susceptible to scratching.
Lighter, etc.: Plastic lenses are a comfort especially in high power needs for eyeglasses as they are lighter in weight for a given power. They are, however, less durable and can scratch in normal use. These factors can be eweighted in the udee
Yes: These are high index eyeglass lense materials which allow a thinner eyeglass and for a given power of lens, are lighter than glass or ordinary plastics. This is helpful to the nose which would otherwise have to support a heavier lense.
Yes but not special: Featherwate is a name used by lenscrafter's for a line of their lenses made from polycarbonate. This is a common material used in eyeglass fabrication. It is the most shatter resistant material available. Lenscrafter's offers it with optional features like anti-glare. Their website has more details. Similar options are available at most retailers.
Disadvantages: Disadvantages: may still need glasses, may need a Yag laser after implant; risk of high pressure after surgery usually unrelated to a well placed implant; other general risks of surgery are rare/very rare: risk of infection, loss of vision, loss of eye, death. lFull answer: Cataract Surgery Options at eyedoc2020.blogspot.comSee 1 more doctor answer
Depends: There are many different types of contact lenses. The best depends on your particular eyes and how you plan to wear them. Your eye doctor can give you the best recommendation.
Most any ...: It is always nice to get the thinnest lenses possible as long as they are impact resistant such as polycarbonate. Once the prescription gets above -4.00 or so it can make a big difference in how the lenses appear.
Observe vision: Under (or the wrong) correction in contact lenses or eyeglass lenses, will be determined by comparing your vision at the extremes of distance with someone likely to have normal vision. If they can see things well that you cannot, then you might have the wrong power. Go to your ophthalmologist to measure this and get the right prescription.
Uncertain ?: I'm not entirely sure of your question but if you happen to be asking what causes the lens of the eye to dislocate, then the following are causes of ectopic lentiis: Marfan syndrome Homocystinuria Weill-Marchesani syndrome Sulfite oxidase deficiency Hyperlysinemia Ehlers-Danlos syndrome Crouzon disease Refsum syndrome Kniest syndrome & others.
What was your Q?: Can we have the first half of your question? This seems like part of a continued thought we need to know more about?
Ask the prescriber: i would sk whoever fit the lenses as to the best way to care for them. If they were bought over the internet I would be very hesitant about wearing them. If not fit or worn properly they could cause damage to your eyes and vision.
Contact lenses: There are several possible reasons why your contacts often tear. The first may be how you're handling them when you remove them. Also, if your eyes tend to be dry, it may help to instill a rewetting drop in your eyes before removing the lenses. In addition, there are certain brands of contacts which tend to tear more easily. Try a different brand of lenses. Talk to your eye doctor about this.See 1 more doctor answer
Sometimes: Spectacles can usually provide very precise improvement of vision. But some circumstances will improve better with contacts. These include the condition keratoconus, and also diseases of the corneal surface as well as very high degrees of refractive power needs. Contacts of course have their convenience and cosmetic effects although glasses in the right hands can be a fashion statement.
