You see through the cornea, which is the transparent part of your eye that covers its front portion. It’s responsible for refracting or bending light. The cornea is ordinarily round, but its structure is sometimes not strong enough to hold this shape. In some people, the normal pressure inside their eyes makes their cornea bulge like a cone. This eye condition is known as keratoconus, also referred to as conical cornea. Keratoconus will not make you go blind. But the changes to your cornea will make it difficult for your eyes to focus without prescription eyewear.
Diabetic retinopathy is a complication from having diabetes. It damages the blood vessels in your retina, causing vision problems that could eventually lead to blindness. Sadly, it is difficult to know when diabetic retinopathy is creeping in because it has zero symptoms. It also does not cause any vision problems until it gets to the advanced stage.
Blue light is present in sunlight, indoor lighting, and electronic gadgets. According to the American Academy of Ophthalmology, the extended use of computers and electronic gadgets results in sleep deprivation, AMD (age-related macular degeneration), and CVS (computer vision syndrome). Statistics show that 90 percent of computer users report having symptoms such as dry eyes, sore eyes, and headaches. This shows a clear connection between blue light and several health issues. That is why there are available interventions, such as blue light lenses. If you want to understand how blue light lenses protect your eyes and more, here’s what you should know.

Here is why you should protect your eyes from UV rays.
This clouding of the eye’s lens, known as a cataract, causes blurred or cloudy vision and other vision problems. In some cases, it can even lead to blindness. People with cataracts often say that their sight is like looking through a waterfall. The word “cataracts” comes from the term for “large waterfall.” It often takes several years for cataracts to distort light rays or prevent light from reaching the light-sensitive retina.
Eyeglasses have long been upgraded from merely being a tool to correct vision problems. Thanks to the influence of social media, the use of glasses has taken on an aesthetic purpose to enhance your signature look.

Nevertheless, you can still arrive at the best option so long as you understand your physiology and what your eyes need.
Scleral contact lenses are large-diameter contact lenses that do not make contact with the entire surface of the eye but instead vault over the majority of it, only touching down on the sclera, which is the white part of the eye. The gap that is beneath plays an important role in the suitability of these lenses for those patients who can’t wear regular varieties.
