What Do Pinhole Glasses Do?
Pinhole glasses are often used by eye doctors who use them as a diagnostic tool to quickly check for vision impairments. Of course, pinhole glasses are sometimes used to treat nearsightedness or astigmatism. Pinhole glasses are also used in conjunction with an occluder, an instrument used to cover one of your eyes while you read an eye chart. The occluder is solid, while the pinhole glasses have a number of tiny pinholes. So, the doctor often uses it to check the potential of your vision.
Pinhole glasses are often used to check corneal distortion and cataracts. A cataract evaluation includes focusing light in the eye to check if vision capability behind the cataract makes it worth performing surgery.

The best frame is the one that suits you.
You can choose the full-frame, because the edge of the lens is relatively thick, which can block the thickness of the edge, so it is suitable for high myopia to choose. They can choose a smaller frame. The size of the eyeglass frame should match the pupil distance so that the edge thickness of the lens is thinner and they are more comfortable to wear. The size of the frame should be proportional to the size of the face. The upper edge of the frame should not be higher than the eyebrow and the eyebrow should not be visible in the lenses. The shape of the frame should match the face shape and skin tone to meet aesthetic requirements. Everyone's face size is different, so the smaller the frame is, the better, based on what fits you and what you like.
Just like an eyebrow, the big feature of the eyebrow frame is that the lines are relatively smooth, with curved radian like women's eyebrows, ergonomic, which can effectively reduce the pressure on the face of the glasses frame. And the design of the eyebrow line frame is beautiful and delicate, smooth and free, bringing you a cool visual experience.
The effects of night blindness on driving
As we age, our pupils will be narrow little by little, so they can't dilate as quickly. The smaller the pupil, the less light reaches the retina, making it harder and harder for the retina to see at night. This is called night blindness, and it's a condition that makes it difficult for your eyes to adjust from bright light to dim light. This makes driving at night especially stressful in your 50s, 60s, and beyond.
