Winter is coming, is your ok mirror still ok?
Due to the rigid "physique" of orthokeratology lenses, which are OK lenses, if they encounter cold weather or brute force rubbing, they are prone to "fragmentation**".
This winter, how to keep your own "golden" OK mirror?How to avoid the occurrence of "broken mirrors"?Let's check out a copy of "OK Mirror Safe Winter Cheats".
Why are OK mirrors particularly fragile in winter?
First of all, it is related to the material, orthokeratology lens is a hard lens, the production of a polymer polymer material, in order to ensure the oxygen permeability of wearing the lens at night, silicon elements that can increase oxygen permeability are added, and the weakness of silicon is "brittle". Therefore, the nursing action must be gentle!
Secondly, it has to do with thickness. At present, the thickness of the OK mirror on the market is mostly 015-0.24mm (about 5 hairs in diameter). It is followed by temperature. In a low temperature environment, the lens becomes brittle when it is cold, and the dexterity of the fingers becomes poor, resulting in a high incidence of fragmentation.
OK mirror how to prevent splinters
Remove the lens to prevent splintering.
01 When there are cracks or scratches on the lens, make sure that the lens is fully lubricated before taking the lens, and take the lens from the suction rod to slide out from the side, and do not use the suction stick to take the lens vertically.
02 Storage, washing, and anti-fragmentation.
Pay attention to the amount of care solution in the storage box: the amount of care solution, pour it into 2 3 of the box.
Pay attention to the method of cleaning the lenses: when cleaning, you should put the concave side up in the palm of your hand, bend the palm slightly, and rub the lens with your index finger in a radial shape for 20 seconds, and do not reverse rub or rub the lens upside down to avoid the lens being broken due to uneven force.
03 Shatterproof lenses when dropped.
When the lenses fall to the ground or under the table, first sit still and ask the people around you not to move around at will, make sure that there are no lenses under your feet, and then look for them slowly and carefully.
When you find the lens, first look at which side of the lens is up. If the concave side is facing up, the finger is dipped in water and gently glued;If the convex side is facing up, you can't press it with your fingers, just use the suction stick gently.
Special attention should be paid to winter care lenses, as the temperature drops, some children may be lazy when cleaning lenses, resulting in lenses not being cleaned. There are also cases where the temperature is too low and the fingers become inflexible, increasing the risk of chips. VIP Ophthalmology summarizes a few winter care and shatterproof guidelines for orthokeratology lenses.
Winter care tips
Moisturize the eye area. When wearing contact lenses, tear quality is a crucial indicator of safety and comfort. However, the dry and cold environment of winter makes the tear film unstable, leading to dry eye symptoms and a decrease in the comfort of wearing contact lenses.
Care Tips: Blink: By opening and closing the upper and lower eyelids, the tears are evenly spread on the surface of the cornea, keeping the eyes moist for more than 15 minutes.
Hot compress: Using a hot towel of 40 to 60 for the eye can promote blood circulation, improve the blockage of meibomian glands, reduce tear evaporation, and thus play a role in moisturizing the ocular surface.
Artificial tears supplementation: When the eyes are dry, drop artificial tears without preservatives to keep them moist.
Increase air humidity: Use an indoor humidifier to improve the moisture of the ocular surface.
Keep your hands clean and soft.
In winter, the dexterity of the fingers is reduced, which makes the lens uneven and prone to fragmentation when caring for and scrubbing the lens, and the dry skin of the finger belly does not achieve the best cleaning effect on the lens.
Care Tips: Warm hands: In addition to washing your hands, keep them soft and wash your hands with warm water before treatment, which will reduce scratches on the surface of the lenses and prevent your fingers from becoming less sensitive.
Trim your nails: Trim your nails smoothly so that you don't scratch your lenses when you wash them.
Lens care. Although OK lenses have a certain resistance to deformation, they are also fragile products, and if the degree of deformation exceeds the tolerance range of the lens, the lenses will break, so special care is required when caring for them.
Care Tips: Storage at room temperature: Lenses, care solution, and rinsing solution should be stored at room temperature, and the temperature should not be too low.
Cleaning temperature: In autumn and winter, the temperature difference between indoor and outdoor is large, and the state of hot and cold is not friendly to the lens, so do not clean the lens immediately when the temperature changes suddenly, you can clean it after adapting to the indoor temperature, and try to control the water temperature between 10 and 20.
The suction stick and lens case are cleaned and replaced regularly.
OK lenses need to be cleaned every day, but the suction stick case is easy to be overlooked, so that it becomes a "dead end" for cleaning. In order to ensure eye health, be sure to do the following!
Care Tips: Case: When storing lenses, lenses can also become contaminated, and it is recommended to replace them every three months. In order to prevent the lenses from breaking when they are taken at low temperatures, try to keep the case containing the lenses at 10-20 degrees.
Suction stick: The suction stick is everyone's right-hand man for daily removal and wearing, and it needs to be cleaned in time after using the suction stick after each lens removal, and it is recommended that the maximum replacement time should not exceed 3 months!
