Ophthalmologists and contact specialists constantly answer all sorts of questions related to wearing contact lenses. In this article we will present the most popular questions and answers to them.
- Is it possible to sleep in contact lenses?
- Indeed, you can sleep in some contact lenses, but not all are designed for this.
Depending on their oxygen permeability, contact lenses are divided into three categories: day wear, which must be removed at night, flexible wear, which can be left on for one or two nights, and extended wear, which can be worn for up to 30 nights in a row (for example, and Pure Vision). But no matter what lenses you wear, there is still a chance of developing microbial keratitis if you do not remove them at night. Therefore, you should wear flexible or extended-wear contact lenses with extreme caution, and regularly see your ophthalmologist.
- Why do you need to replace contact lenses on time if everything feels fine?
- Everything may feel fine, but timely replacement of contact lenses is the key to eye comfort and health.
After the expiration date, deposits from tears, hands, and the environment begin to accumulate on the lenses. They can damage the surface of the lens, cause eye irritation, visual disturbances, and lead to eye health problems.
- What to do if you lost one contact lens? Can I buy contact lenses individually?
- That is why contact lenses are sold in packages. Firstly
, the contact lens may get lost. Secondly, You don’t have to rewear your lenses when their wearing period ends and you haven’t bought a new pair yet. Third, the price per pack is often slightly more expensive than for two contact lenses. So why pay more? Fourth, the manufacturers themselves strongly recommend purchasing contact lenses in packages - lenses packaged at the factory are less susceptible to external influences than when the package is printed. In addition, all information about the lenses (material, moisture content, expiration date, batch number, etc.) is indicated on the box, and not on the blister.
Besides, You should always have contact lenses and glasses in stock.
If there is eye irritation, if you have a cold or an infectious disease (which means there is a lot of protein in tears and contact lenses will quickly become unusable), then you need to use glasses or daily lenses.
- If I have different vision in my right and left eyes, what should I do?
- In this case, you need to buy two packs of contact lenses with different diopters
for each eye. The advantage is that two packages will last you twice as long.
- Is the prescription for glasses suitable for the correct selection of contact lenses?
- No, the prescription for glasses is not suitable
Therefore, it is necessary to consult an eye doctor to write an appropriate prescription for contact lenses.
- What to do if your vision is not good enough even with contact lenses?
- Insufficient vision in contact lenses can have many causes.
This could be due to dry eyes, poorly fitted lenses or lenses purchased using an outdated prescription. It may also be a sign of more serious problems not related to contact lenses. If you have any vision problems, you should consult an ophthalmologist.
- Is it true that daily contact lenses are more expensive than longer-wear contact lenses?
- lenses will cost more than 2 contact lenses. However, they do not require any care, unlike, for which care you usually need to purchase.
So the difference in cost of wearing these two types of contact lenses becomes less significant. And if you consider that they are the safest, since various contaminants and bacteria do not have time to deposit on them, then it becomes clear why this type of contact lenses is becoming more and more common in the world.
- What is more important: oxygen permeability or moisture content of a contact lens?
- Oxygen permeability is definitely more important
However, if you have a sensitive cornea, then moisture content will be of great importance.
- How to combine Visine and contact lenses?
-
Many people are interested in how Visine and lenses are combined. If you wear contact lenses, you should remove them before instilling Visine and put them back on only after 15-20 minutes.
No drops, except special ones, should be instilled into eyes with contact lenses on, as this leads to more or less damage to the lenses.
- Is it possible to wear contact lenses during an exacerbation of the herpes virus?
- Wearing contact lenses for herpes is possible only during the period of remission, that is, the absence of signs of the disease, as well as in the absence of signs of colds.
To avoid additional infection with herpes, it is better to use.
Almost everything is suitable for disinfecting contact lenses during the period of remission of ocular herpes. Contact lenses that have “survived” the onset of an exacerbation of ophthalmoherpes should be replaced.
- Which lenses are the best? (question from most clients)
- There are no better or worse lenses, there are lenses for different purposes and different both in terms of wearing time and other parameters
, and precisely thanks to the existing diversity in the contact correction market, Today, everyone can choose the contact lenses that suit them.
Several questions for people who wear contact lenses for vision correction and received the best answer
Answer from Ashan Ashan[guru]
Well, there are contact lenses for both 3 months and six months
There is no way they can fall out of your eyes unless you rub them yourself.
a couple of hours is possible, I don’t recommend more (they must be constantly moistened when blinking, otherwise they will dry out)
The ambient temperature does not affect the lenses (if they are on your eyes)
It is not recommended to wear lenses during acute respiratory viral infections or other infectious diseases, because lenses, due to their structure, absorb anything and everything, including germs, etc., then inflammation may occur. Smoking while wearing lenses is also not recommended.
If there is a temporary increase in temperature, then it’s okay
if it falls on the floor, pick it up and rinse it with lens solution (it must be disinfectant)
Answer from Evgenia Unichenko[active]
The doctor said to wash only with a solution. Do not use water. The lens will absorb bleach.
Answer from Christina Chris[guru]
need to be changed every month because they seem to wear out, the image over time is not as clear as at the beginning. They cannot fall out of the eye due to a strong fall or sneezing; on the contrary, at first, until you learn how to put them on and take them off, there will be difficulties. You can sleep for a couple of hours without removing the lenses, but you will feel your eyes burning and discomfort.
There is no need to wear clothes when you have a cold, because at this time the body is very sensitive to viruses and bacteria, and you can catch an infection in your eyes. Air temperature -15 and below cannot affect the lenses. If the lens falls somewhere on the floor or some other dirty place, you are unlikely to find it, and if you do find it, it is better not to use it, you will get an infection.
In general, the thing is very convenient, at first there may be difficulties, but after about half a month or a month you won’t even feel it))) Doesn’t depend on age))
Answer from Alexey Dubin[active]
Ahhh, so many problems) I wore for about 7 years, living my life to the fullest, and they only fell out when I accidentally hit my eye with my finger/fist, directly touching the lens. Somehow I fell asleep in one-day shorts in my outfit - they dried out, fell out, but they were denser, not for sleeping (but more oxygen-permeable), in the others they never fell out, I dived, my eyes flooded with water because I didn’t close them tightly, I blinked - normal.
When I’m sick, I sit at home wearing glasses, like an intellectual in a robe, where to go, always wearing lenses, but daily ones and the norm
But it’s better not to pick it up from the floor, I disdain to put on one-day clothes from a sterile blister (but with -5 I have to), I don’t know how you put them in the solution and put them on))).
Answer from Elena[guru]
Our accountant's daughter was very fond of lenses and was careless about the rules for their use. I got keratitis (inflammation of the cornea of the eye) with fever and pain in the eyes - I was taken to the hospital by ambulance. So be careful with lenses.
Answer from Natasha Usenko[active]
Because they have a limited shelf life, there are lenses for three months, there are for a month, there are even daily ones. I once lost it because I rubbed my eye very hard, but when I sneeze and fall, I think not, because when a person sneezes, he closes his eyes. I was sleeping, this is not advisable, but nothing criminal happened to me or my lenses. I think not, because you can wear lenses in winter. Microbes that get into the eye cannot escape because the lens is in the way, which can cause discomfort and further illness. If you're at home, it's better to take it off, it definitely won't do any harm. I’ve had it fall several times, just rinse it well, if possible under the tap, but with low pressure, otherwise God forbid you’ll wash it off.
Answer from Jenny[guru]
1. Because they are made of thin polymer that breaks down. There are coarser lenses with a replacement period of 3 months and 6. There are also thin ones - their period is a day.
2. No, firstly, when you sneeze, you instinctively close your eyes, and the diameter of the lens is large (here in front of me - 14.2 mm) and it goes behind the eyelid, so you can hold it.
3. Yes, of course it is harmful - the presence of a lens increases the pressure in the eyeball. But taking a nap on the bus is sacred!! !
4. The lenses are glued to the eye - and they are as warm as the eye. Even at -35 (Checked).
5. There is a general weakening of the body and impaired lacrimation due to a runny nose and general stress. And in general - it’s tempting to sleep - and then see point 3. Although they wear it.
6. It can be bad even at a temperature of 36.6 - it’s a matter of the state of the body.
7. Rinse, there are special solutions. You store them as you wish and clean them from protein deposits. You will have 2 more buckets with special equipment. They fall on my mirror all the time. Got wet - and in front.
Answer from "Only girls in jazz!!!"[guru]
Lenses tend to get dirty, so they are replaced. They can fall out when swimming, diving, in the shower, when washing. Theoretically they can fall out from sneezing, but in practice I have not had such cases. You can sleep all night. I haven’t noticed the effect of temperature on the lenses, I wear them in cold and hot weather, also during flu, acute respiratory infections, ARVI, I don’t bother too much with it. If you fall, pick it up, clean it, you can continue wearing it.
Contact lenses are an excellent alternative to corrective glasses. There are many reasons for this. They are invisible when worn, comfortable, and provide clear and contrasting vision.
However, some people worry that the optical product may get lost in the eye. Of course, such a problem, although quite rare, is still not excluded. How to avoid unpleasant consequences and what to do if the lens is lost?
Contact correction means are a purely individual thing, which should be selected by a qualified specialist taking into account your individual parameters. Patients often ask ophthalmologists the question: can it get lost in the eye? What to do in such a situation, do I need to buy additional funds? As a rule, if the selection was carried out in a hospital, clinic or private ophthalmology office, then the optical products prescribed by a specialist are not felt when worn and do not cause discomfort. When put on, they are located at the level of the pupil and should not move when blinking and other movements of the visual organs. However, due to the fact that the eyeball is spherical in shape, the possibility that the product may move behind the eyelid cannot be completely ruled out. Why is this happening?
Common Causes
The main problem that some users face today is incorrect selection. This often happens to those who neglect the recommendations of the attending physician or completely refuse to visit him. If the base curvature was chosen incorrectly, the product will not fit tightly, which can lead to its further loss. In addition, how comfortable the correction device will be located largely depends on the material used in production.
For example, hydrogel optical products, characterized by a high moisture content, may not immediately take the required position and are more at risk of loss than others. In this regard, silicone hydrogel lenses for the eyes are considered more practical, which, according to ophthalmologists and users themselves, are much easier to handle and usually do not cause such problems. Another challenge that beginners may encounter is maintaining proper donning technique. The fact is that when you bring the correction agent to the organs of vision, a protective reflex may be triggered, consisting of rapid blinking. Because of this, it may not have time to take the required position on the cornea and, as a result, get lost.
What to do if the lens is lost in the eye?
If before going to bed, having decided to remove optical products, you find that you cannot find one of them, you should make sure that it is really missing. Contact optics are thin and transparent, and therefore are not always noticeable.
If, after correctly performing these manipulations, you think that the lens is lost, then you should drip your eyes with special moisturizing drops, which you can order in our online contact lens store. Repeated instillation will allow you to remove the product from under the eyelid. The fact is that the liquid will allow it to “float” out, after which it will not be difficult to detect it. According to contactologists, it is much more convenient to ask another person to do this. If it is not possible to remove the product in this way, you should consult an ophthalmologist. Moreover, the sooner you do this, the better for your health, since a foreign body can lead to the development of conjunctivitis - inflammation of the mucous membrane.
Sometimes there are cases when the lens may fall out. And then the question arises, what to do and whether it can be used further.
Such situations must be treated very carefully, because it may happen that you can lose them, for example, if you remove them over the sink and forgot to plug the drain hole in advance. If you do not take care of this in advance, you may well find yourself in a situation where the lenses end up in the pipes, which was hardly part of your plans.
Sometimes it can be quite difficult to find a fallen lens, because it falls completely silently, and is also very small, so it can easily fall into any gap. Well, it’s worth mentioning separately about the color of the lenses, because if they are colored, then you are, one might say, lucky, since they are much easier to find than colorless ones.
If you look for your lens for a long time, then over time it may wrinkle and dry out, so even if you find it, it is not a fact that you will be able to identify it, mistaking it for some kind of garbage.
So what to do if you do find it? Handle it very carefully as it becomes very brittle when dried and can crack easily. The fallen lens should be carefully lifted using a piece of paper, after placing it under it. After you have safely lifted it, you have two options for what to do, depending on what kind of vision correction you are using - daily contact lenses or scheduled replacement lenses. In the first case, of course, they should be thrown out immediately and replaced with the next batch. If you use contact lenses for a month or a quarter, then place them in a special container with solution overnight. If the next day the lens has not acquired its shape and has not become elastic, it cannot be replaced and will also have to be thrown away. Also, do not forget that before you insert the lens into your eye, you should thoroughly rinse it with a special solution. If you feel any discomfort after putting it on, this most likely means that it was damaged and will also have to be thrown away and replaced with a new one. The fact is that after a fall, damage and small scratches could form on it, which cause discomfort when using it.
In such cases, the ideal solution is to use daily contact lenses. As the name suggests, this vision correction device needs to be worn for a limited period of time - only one day. Agree that this is very convenient - every morning you just need to put on a new sterile lens, and at the end of the day you just take it off and throw it away. And as mentioned above, even if you accidentally drop it, you can always just throw it away and get a new one without resorting to additional manipulations with the solution.
Many people now choose instead of the usual glasses comfortable and discreet soft contact lenses that make your appearance beautiful and natural, allow you to move easily and feel very comfortable.
However, when wearing these products sometimes Unforeseen situations arise, for which you need to be prepared.
One of these problems Although it doesn't happen often, it can be very scary- the impossibility of removing it from the eye, because it “hid somewhere”, “fell” behind the eyelid. The problem is actually solvable, and nothing terrible will happen!
When the lens can roll behind the eyeball
The lens can move inward and get “lost” in the eye for several reasons:
- The human eye is spherical in shape, so if you rub too hard eyes, the product may slip from its “home” place and move, clasping the eyeball in the place where you moved it.
- This happens if Go to bed in lenses that not intended for long-term wearing.
During sleep, the eyeballs rise up while the eyelids are lowered, respectively, the lens fits tightly to the upper eyelid. Contact(clutch) intensifies with the conjunctiva because the eye doesn't blink, no air access, A the amount of moisture decreases. Thus, the optics sticks into the eye, especially if even the slightest inflammatory processes are present. When a person wakes up and assumes a vertical position, it moves upward along with the opening of the eyelid.
- Under unfavorable circumstances, if the eyes dry out a lot, the lens appears "lost" because it is stronger sticks to mucous membranes cornea and is more difficult to detect in the eye.
- She “runs away” behind the eyelid if incorrectly installed, namely reversed side out, or damaged its surface (torn and changed shape).
Photo 1. A visual representation of the lens in the correct position for installation and inside out.
In most cases, the lenses are “hidden” under top eyelid, where you need to look for them. Under lower They get into the eyelid if they stick together and fold in half during dressing. In this case, the lens falls under the lower eyelash row, but it is clearly visible and removing it is not difficult.
Attention! If contact optics installed correctly, it fits well and stays snug without getting tight throughout the day no discomfort.
Can a foreign body get stuck in the eye and stay there?
The first thing you need to do when you find yourself in a similar situation is calm down. You can be absolutely sure that nothing won't fall into the eye socket.
Important! The nature of the human eye is very wise: over time, our eye, akin to the ocean, takes out all kinds of garbage, and is capable of self-purification. Therefore, sooner or later you will extract it.
Everyone knows from the school anatomy course that the eyeball securely attached in the eye socket, it surrounded by superior, inferior, oblique, and intrinsic and extrinsic muscles, thanks to which it moves. The muscles are attached directly to the eyeball and are securely fixed by fibrous connective tissues, which will not allow optical devices to penetrate into the depths. Therefore, the lens can be found only on the convex part — cornea.
How to remove a lens from under the upper eyelid: 4 ways to remove the optics
Having made sure that the lens is difficult to remove due to dry mucous membranes, we take attempts to extract it.
- First you need to apply eye drops several times moisturizing drops and do it carefully movement eyeball right-left, up-down, and circular. A large amount of liquid will help return the lens to its original place and remove the product from the eye.
- Method two. After dripping the eye, lightly grab the skin of the upper eyelid of the closed eye in the place of the greatest depression in the orbit thumb and forefinger fingers, do it slowly gentle movements fingertips along the eyeball from top to bottom. Opening my eyes, blink frequently. Repeat the procedure several times.
- If this doesn't help, prepare mirror and good lighting, which will help you see where exactly the culprit of your troubles “sits”. Tilt your head back as high as possible, so that the chin takes a horizontal position. Lift the eyelid by the upper eyelashes and try to see the location of the lens. (For best results, apply moisturizing drops and continue to blink frequently).
If you can't move it, try pick up its edge with special tweezers or clean finger(but this advice is applicable if you are sure that you are absolutely calm, sober and the vision of the other eye allows you to see what is happening). A misaligned lens can usually be easily removed in the usual manner. After this, it is better to instill any available drops for preventive purposes. anti-inflammatory eye drops.
Photo 2. A woman carefully removes a contact lens from her eye using her index finger and thumb.
- And the last one, the most extreme way. Prepare deep clean bowl small sizes with chilled boiled water(a glass and a half is enough). Place it on the table and lower your face so that the eye is immersed in water.
Relax and imagine that you are swimming in the sea or lake (after all, it’s not so scary when splashes get into your eyes, or we look underwater, diving and swimming). Open and close your eyes in the water, often blink, you can slightly move the upper eyelid with your index finger. The lens can easily slip off.
The only problem The method is to avoid throwing out the water with the child, that is be able to catch optics of water. If you are unable to catch it with your hands, use a strainer and carefully pass the liquid through it. Place the found lens in the solution, and rinse your eyes with running water or chamomile decoction.
