How lenses protect your eyes?

The world is a beautiful place, but is that so without your eyes? Surely not. They say, “Beauty lies in the eyes of the beholder”, but what if the beholder lost their eyes?

It’s only when we look from a blind person’s perspective that we understand the actual value of having healthy eyes. Sadly, some people are born blind or with weak eyes, but for most, there are ways to maintain the quality of sight. To discuss this topic, firstly, let’s have a look at why it happens.

Why and when do the eyes weaken?
Oftentimes, older people have vision problems, and the situation is quite apparent. They might have macular degeneration, diabetic retinopathy, glaucoma, cataract, and/or various other issues.

But sometimes, especially in modern times, low vision issues are seen at a very young age. Technology has made our lives more comfortable, but on the other hand, it also has leveled up the setbacks as well. We might enjoy watching movies on our laptop or are stuck to games on a smartphone for long hours, but one thing we don’t notice often is it negatively impacts our eye health.

Moreover, UV rays coming out from the sun is another common reason behind the poor eye health these days.

But how do we tackle this? Well, read on to know.

What to exactly do to maintain the quality of your eyes?
Primarily, regular exercises and better nutrition are the ways to maintain the quality of one’s eyes. However, if that doesn’t work for someone, use of corrective lenses can.

How lenses protect our eyes?
Enhanced exposure of eyes to bright light and reflection makes it much more difficult to see outdoors. In that case, we need to make use of lenses to protect our eyes.

If one wants to understand how lenses protect our eyes, they first need to understand the basic functioning of our eyes. Our eyes include a retina that is a layer of cells that reacts to light. Whenever we watch anything, a reaction is performed, and the signals are sent to the brain, which further translates into the activities you are viewing.

These light rays ideally focus on the surface of the retina for perfectly visioned people, but when it finds any interruptions in between, the image starts altering-- It might shrink or blur somehow.

That’s where eyeglasses come in.

Eyeglass lenses are generally curved pieces of glass-like mermaid tears that work to bend light rays as they approach your eyes. These lenses only help the rays in focusing on your retina rather than behind or in front of it.

Based on where the rays fall, there are two types of lenses used to correct the position of the rays: convex and concave. In convex lenses, the curve is outward-facing, i.e., it’s for nearsighted people. In concave lenses, the curve is inwards-facing, i.e., it’s for farsighted individuals. That’s everything about the vision and lenses.

Wrap up:
Either concave, convex, on in some cases, bipolar, lenses help people maintain healthy vision. Of course, technology has given this to us, but healthy eating and exercise should still be one’s priority to maintain eye quality.
