Cloudy Crystalline Lens – the Cataract!

sim-cataractCataracts are one of the leading causes of blindness in the world. Cataracts are formed when the natural crystalline lens in the eye becomes clouded or opaque. Cataracts can be removed surgically once they become significant enough. Cataract progression can be minimized by wearing sunglasses to block harmful UV light from entering the eye. Nutrition has also been found to play a role in minimizing cataract progression. Many studies have shown that the vitamins C and E are helpful in delaying cataract formation. Studies have also shown that the daily intake of the carotenoid antioxidants lutein and zeaxanthin, the only carotenoids found in the lens, can be beneficial as well. These nutrients can be obtained through a healthy diet of fruits and vegetables, or through vitamin supplementation. Many eye doctors carry supplements in potencies stronger than that which can be obtained over-the-counter, as these nutrients have also been found to benefit the area of the retina called the macula.

Can a glasses prescription be used to get contact lenses?

vision wearOur patients sometimes ask us if a they can use their glasses prescription to purchase contact lenses. The short answer is no and if you see an eyecare professional that is using a glasses prescription for contact lenses, we strongly recommend that you RUN as fast as you can out of that office. A competent eyecare professional understands that taking shortcut can result in permanent vision loss for his/her patient. That said, there are several reasons why a glasses prescription cannot be used for contact lenses.

First, the strength of glasses and contact lenses are often different. This is because contact lenses sit closer to the eye and therefore don’t have to be as strong in near-sighted patients, and must be stronger in far-sighted patients. Also any amount of astigmatism is corrected in glasses, whereas astigmatism is only corrected precisely once it reaches a certain level in contact lenses, otherwise the near-sighted or far-sighted power is adjusted to account for this small amount of astigmatism.

Second, and most importantly, is that contact lenses must be matched to the measurements of the cornea that were obtained in the contact lens fitting. On a contact lens prescription the curvature and diameter of the contact lens are specified. The precise brand and material of contact lens must also be specified on the contact lens prescription. This is because all brands of contact lenses will fit, feel, and behave differently on the eye.

Most of our patients are unaware that contact lenses are a regulated medical device. Make you have a reputable eyecare professional perform a contact lens evaluation and fit. This process should take at least 2 visits to make sure that the contact lenses prescribed are right for your eye. Equally as important is to make sure you follow the doctors instructions as to how long you can wear the prescribed contact lenses and what type of solutions to use. Remember, your sense of sight is so important. Don’t risk damaging one of your most precious senses. See an professional and follow the instructions. Anyone is willing to sell you contact lenses without a proper contact lens prescription  is putting their profits ahead of your health.

What is a Pinguecula?

A pinguecula is an area of degeneration of the deep conjunctival layers.  In other words, it is an area of disrupted tissue on the white part of one’s eye.  Usually located at the 3- or 9-oclock position near the cornea the tissue may appear slightly yellowed or red due to an increase of blood vessels in the area.  The tissue may be raised or flat.  Pingueculas arise from over exposure to UV light or chronic irritation of the tissue caused by dust or wind.  It is important to protect one’s eyes from such elements with sun or safety glasses depending on the environment.  If the tissue is continually subjected to irritation it can expand into the cornea and cause dryness, discomfort and eventually decreased vision.  Once this occurs surgery is often needed to remove the tissue.  It is important for people of all ages to protect their eyes from sun light and other irritants to prevent pingueculas from forming.

What is astigmatism?

Understanding AstigmatismA lot of our patients ask us what astigmatism is. We find that most think it is a disease or growth in the eye. It is actually just a refractive condition similar to near-sightedness or far-sightedness. It is caused when the cornea or lens of the eye is not perfectly spherical like a baseball, but instead has two curvatures like a football. The curvature is one of the main things to give power to the cornea or lens. Therefore if they have two different curvatures, they have two different powers, and they bend light rays to two different points in the back of the eye. This causes distortion or blur. This can be accommodated for by prescribing glasses or contact lenses with two different curvatures to counteract that of the eye. What to learn more?

Reasons you should not sleep while wearing your contact lenses!

Traditionally there have been two main reasons why sleeping in contact lenses can be dangerous. The first is that the cornea becomes starved of oxygen and new blood vessels will grow into the cornea. The blood vessels are not transparent like the cornea and will block your vision. With the arrival of the newer silicone based contact lenses that are oxygen permeable, this problem has been greatly minimized. However the other reason for not sleeping in contact lenses still exists. That is that metabolic waste products from the cells of the cornea get trapped under the contact lens while sleeping and cause an inflammatory reaction. This can lead to infections, ulcers, and scarring, all of which can lead to permanent vision loss.

You only have two eyes… vision is so important. Don’t risk harm to one of you most important senses. If you are interested in special contact lenses which are approved for overnight wear, please give us a call.

Do you ever have blood in the whites of your eyes?

Often patients will come into the optometrist’s office in a panic because they awoke with the white of their eye completely bloody. While looking very serious, this is actually no more serious than a bruise. This is called a subconjunctival hemorrhage, and is due to a broken blood vessel lying between the white of the eye and the clear conjunctiva that lies over top of it. These blood vessels can often break due to getting bumped in the eye, or more commonly from anything that temporarily spikes your blood pressure. These are commonly seen in people who have coughing fits, a history of vomiting, or any kind of straining, whether it be due to heavy lifting, pushing during child birth, or straining using the bathroom.The bloody appearance usually has very few other symptoms. There is typically no pain, discharge, or change in vision. The blood will be reabsorbed by the body in approximately a week. Because other more serious conditions can cause redness in the eye, it is always best to see your eye doctor with any new onset of redness.

Sleeping with Contact Lenses

Many people want a contact lens in which they can sleep overnight for multiple nights. There are even some contact lenses that are FDA approved for 30 days of continuous wear. These contact lenses gained this FDA approval because they are very permeable to oxygen and let the cornea “breathe”. However, sleeping in contact lenses, whether it be traditional contact lenses or the newer breathable ones, still greatly increases the risk of eye infections. These eye infections, besides being uncomfortable, can be potentially vision threatening. They can lead to corneal ulcers, which have the potential to permanently scar the cornea. This can lead to permanent decrease in visual acuity or blindness. To greatly minimize this risk, it is recommended that all contact lenses be removed and disinfected nightly. As always, at the first sign of any redness, pain, or change in vision, it is advised that your contact lenses should be removed immediately and you should contact your eye doctor.

Changing Eye Color

I have seen a number of patients over the past few weeks who have noticed their dark brown eyes turning a whitish blue color. This is known as Arcus Senilis. The change in color is due to a build of lipids and cholesterol in the corneas stroma. The deposits usually form in a ring like shape around the outer edge of the cornea which lies on top of the iris, or colored part of the eye. This whitish blue ring covers the iris’s natural color. The appearance of this ring can be an indication of hypercholesterolemia if occurring at a young age but can also be seen in some patients over 60 who have normal lipid levels. If you begin to notices changes in the appearance of your eye color it is best to follow up with your optometrist for a full evaulation.

Multifocal Contact Lenses

For contact lens wearers over the age of forty, an excellent option for vision correction is multifocal contact lenses. One has to go into a multifocal fitting with the right expectations, however. Unlike a glasses multifocal which has distinct areas for distance and near, a multifocal contact lens blends distance and near simultaneously.This results in very good vision, however it will not be as good as distance only contact lenses or glasses. Many people will get some glare and haloes with nighttime driving. Also a pair of readers may be necessary for very small print, especially in low lighting.
