Design

      My design is glasses in which lenses would be suitable for several sight powers, so you won't need to change lenses for a while, even if you sight power changes. One pair of glasses can be suitable only for 30 different sight powers. Otherwise the lens would be too thick.

      Here are two examples of how can glasses look.

So, glasses can be any shape, color and material. The price will depend on design the glasses. 

I've also completed a research on different types of lenses.

·       Polycarbonate lenses. These eyeglass lenses are impact-resistant and are a good choice for people who regularly participate in sports, work in an environment in which their eyeglasses may be easily scratched or broken, and for children who may easily drop and scratch their eyeglasses. Polycarbonate lenses also provide ultraviolet protection.

·       Trivex lenses. These lenses are made from a newer plastic with similar characteristics of polycarbonate lenses. They are lightweight, thin, and impact-resistant and may result in bettervision correction than the polycarbonate lenses for some people.

·       High index plastic lenses. Designed for people who require strongprescriptions, these eyeglass lenses are lighter and thinner than the standard, thick "coke bottle" lenses that may otherwise be needed.

·       Aspheric lenses. These eyeglass lenses are unlike typical lenses, which are spherical in shape. Aspheric lenses are made up of differing degrees of curvature over its surface, which allows the lens to be thinner and flatter than other lenses. This also creates an eyeglass lens with a much larger usable portion than the standard lens.

·       Photochromic lenses. Made from either glass or plastic, these eyeglasses change from clear to tinted when exposed to sunlight. This eliminates the need for prescription sunglasses. These eyeglass lenses may not darken in a car because the windshield could block the ultraviolet rays from the sun.

·       Polarized sunglasses. Light reflected from water or a flat surface can cause unwanted glare. Polarized lenses reduce glare and are useful for sports and driving. These lenses may cause the liquid crystal displays on the dashboard of cars to appear invisible.

Child Friendly Syringe - Rabbit

My task was to create a child friendly syringe. I thought of a rabbit because they are fury and cute. When children are afraid of needles, nurses could give them a toy, so children would be distracted from a needle. I made a syringe like a carrot,so the child would think it's also a toy.

For head and legs I used spheres and half spheres shapes. For nose I used pyramid shape and for mouth - round roof shape. I found bunny ears shapes in extras. And terrain in generated shapes.

For a carrot I used cone and half sphere shapes. Greens are originally a tree shape in generated shapes. For needle I used a sphere.
