If you are a myopic person and want to buy contact lens online.You must know these before buying contact lens online.
Friends long-term used of computer are not suitable to wear contact lenses
The researchers said that contact lenses that commonly used are manufactured by the polymer material, although they are various different brands of materials, but the experiment showed that all of the contact lenses under radiation exposure by the computer will break down gradually degenerate , making the variation of the original material molecules, the decomposition of small molecules, and some will reach the lens through the lymphatic circulation, and the combination of the lens of the repair tissue, resulting in a new polymer.
Generally speaking, a small amount of polymer is expelled from the eye to the ocular surface, and eventually gum. But the output is more time, more than the size of the polymer discharge hole size, this time, the debris will accumulate within the eye in the crystal body, giving rise to cataract.
Experts Call for the ones wearing contact lenses and often using computer, must put off the contact lenses when having a rest, and have sufficient time for the eyes discharge of waste, if not so, it is easy to suffer from cataracts.
The appropriate time for wearing:
The normal reaction of wearing by the beginning :
Slight dry feeling, photophobia, transient blurred near vision, foreign body sensation, visual zoom in or out
The above is normal, after a period of adjustment period, one or two weeks will disappear naturally. Spectacles worn by the beginning of the week, and if the symptoms continued to increase, then you'd better remove the contact lens immediately.
Knowledge of contact lens UV
UV contact lenses through the increase of chemical raw material monomer in the UV absorption material, can block 99% of harmful ultraviolet B and 80% of the ultraviolet A, ultraviolet rays enter the eye through the cornea, causing major eye damage, such as cataract, snow blindness, etc. . Close to the hidden eye lens, eliminating the light leakage around the mirror frame, non-staining clear need for indoor and outdoor occasions. But the mirror does not cover hidden around the eye tissues, transparent lens does not relieve summer on the strong glare and winter snow, so the serious pollution in the outdoor season and the ultraviolet region, we advocate coupled with UV protection to wear sunglasses or sun Sports transparent protective goggles. Compared with the normal function of contact lenses, multi-layer anti-UV protective contact lenses to prevent eye damage caused by UV, health and safety more secure.

Notes for contact lenses used outdoor, I want to remind you:
Contact lenses have the two biggest enemies - cold and dirty, here are some simple tips to deal with them.
◎ Outdoor activities usually dirty, dust and other small particles when mixed in between the contact lens and eye, because the friction generated by eye movement pain is a very disturbing thing - this will cause friction or even permanent eye disease. So, when you really need to touch or remove the contact lenses when the eye, make sure your fingers are clean, wash hands with soap if no conditions, should at least carry the water to rinse them several fingers come into contact with the eye . When there is no water, that the use of contact lens care solution rinse fingers stronger than the direct eye contact.
◎ camping in the outdoors, in order to avoid wearing contact lenses when the loss of picking the best approach is to support your elbows on the moisture mat or sleeping bag, and then take off or wear contact lenses, so do not even contact lenses fell off, and fell in moisture-proof pad or sleeping bag fall to the ground than on Shanghao find much, but also much cleaner than the ground.
◎ must remember to prepare luggage before departure time, take care solution bottle filled with travel, if careless forget to bring one o'clock, after boiling the water in clean containers after cooling to temporarily replace the care solution.
