Contact lenses.

[n00kie]

It would be desirable still or even for time to mention or touch this subject. I wear lenses a year, in current of this time it was necessary to change lenses 4 times. neodnorkatno it was necessary to consult at experts on lenses, but all of them as repeat one, that lenses " are a product ecologically pure or clean, not putting or rendering harm, long in the wearing, completely replacing glasses or spots " .ja certainly I understand, that they need to shake out more money from buyers but while niodnogo the fair person from this area to meet it was not possible. With ophthalmologists razgovr in general always kratok since they have small predstvlenie about lenses. You, how not interested expert, can tell or say about collateral influences of lenses on eyes? It is necessary to do or make what intervals in wearing lenses, we shall tell or say in a half-year passing on glasses or spots?
And more one question, not in a subject certainly, but in view of my laziness to open other subject, there and then: at me-5, glasses or spots it is necessary to wear a myopia exactly-5 or all to resort to sparing conditions at-4.75?
