ENVELOPE VS POSTCARD. It is traditional to provide an envelope for your guests to send their reply back to you. In todayâs day, some brides will opt to have a postcard style response card. The postcard style saves on paper (no envelope needed) and will save on postage (you will be able to use a postcard stamp).
For other patients, it's the frame, not the lens that's causing the problem. If the earpiece is too tight or presses on the temple, or over and behind the ear, this can irritate nerves and lead to headaches. Having the frame resized or earpieces adjusted might solve this problem.
The lens acts by focusing light rays onto the retina. However, before the light rays hit the retina, it will first go through the posterior chamber and the vitreous humor, which makes a clear, jelly-like substance that helps retain the shape of eye. The 5 th and innermost layer of the eye is the retina. It has a total of 10 layers that have light sensitive cells which include rods and cones. These light sensitive cells create signals that travel down the optic nerve and to the back of the brain for further understanding of what we are seeing.
